Description
Technical field
Present invention relates in general to optical transceiver.More specifically, the present invention relates to such optical transceiver, it can be configured to carry out the customization record of operation information by the input from host computing system.
Background technology
Calculating and networking technology have changed our world.Along with the amount of information that spreads through the internet increases, it is more important that high-speed transfer becomes.Many high speed data transmission networks rely on optical transceiver and similar equipment to come the transmission and the reception of the convenient digital signal of implementing with the form of light signal on optical fiber.Thereby can in huge various high-speed applications, see optical-fiber network at moderate as small-sized Local Area Network as Internet backbone.
Usually, the data in such network send and realize such as laser or light-emitting diode (LED) by optical transmitting set (being also referred to as electrical to optical converter).When electric current passed through, electrical to optical converter was luminous, and the light intensity that is sent is the function of current magnitude.Data Receiving realizes by optical receiver (being also referred to as optical-electrical converter) that normally an example of optical receiver is a photodiode.Optical-electrical converter receives light and produces electric current, and the value of the electric current of generation is the function of the light intensity of reception.
Optical transceiver also uses various other elements to come assist control light to transmit and receive parts and handles various data and other signal.For example, such optical transceiver generally includes the driver (for example, being called as " laser driver " when being used for the driving laser signal) that is configured to the operation of control optical transmitting set in response to various control inputs.Optical transceiver comprises also that usually the special parameter that is configured to the data-signal that receives with respect to optical receiver carries out the amplifier (for example, often being called as " post amplifier ") of various operations.The operation of control circuit (hereinafter referred to as " controller ") control laser driver and post amplifier.
The operation of optical transceiver is easy to be subjected to the influence of its running environment and its other operational factor.A tangible example is a laser bias current.If transmitter bias current is drifted about up or down, can expect that the luminous intensity that reflector produced will change.The luminous power of emission and the luminous power of reception also are important operational factors.The mains voltage level that offers optical transceiver also influences its performance.
In addition, temperature can change the operation characteristic of optical transceiver self.Particularly, one degree centigrade of the every change of temperature, the wavelength output of laser may be drifted about about 0.3 nanometer (nm) to about 0.6 nanometer (nm).Because laser produces heat at run duration, this can have remarkable influence to the operation of laser.Wavelength change can cause crosstalking, and mixes in the next emission of the situation of crosstalking and another emission.In addition, the wavelength of the variation that is caused by the laser temperature that changes may cause different optical fiber attenuations.Therefore, the temperature of laser and wavelength have tremendous influence to the true(-)running of optical transceiver.
The high temperature of optical transceiver self may cause laser not only but also also have temporary or even the nonvolatil fault of other electronic unit in the optical transceiver.Therefore, the temperature of optical transceiver also is important for the operation of optical transceiver generally.
In order to provide suitable cooling or heating to optical transceiver and/or laser, particularly depend in the optical transceiver of temperature at the performance height, often use thermoelectric (al) cooler (TEC).Such TEC cooler heats according to the sense of current that puts on this TEC cooler and value or cools off.Therefore, the TEC electric current also is important operational factor.
Thereby these different parameters (for example laser bias current, transmitting power, received power, supply voltage, laser wavelength, laser temperature, transceiver temperature and TEC electric current or the like) are important for the operation of optical transceiver.Yet because record may be for why the break down traditional mechanism of the critical event that provides indication of transceiver constantly, after optical transceiver broke down, often being difficult to diagnosis problem was what.For example, if the ceiling temperature rated value of optical transceiver is 85 degrees centigrade, if then the temperature of optical transceiver reaches 110 degrees centigrade, optical transceiver just may break down or permanent damages.Yet, after true the generation, be difficult to find that optical transceiver has stood unsuitable temperature.
Therefore, record is that the mechanism of important incident is favourable for the operation of optical transceiver, thus make these incidents can be when being used to understand the optical transceiver operation afterwards residing situation.

Fig. 1 shows the optical transceiver 100 that can adopt principle of the present invention.Though will describe optical transceiver 100 with certain the level of detail, optical transceiver 100 just is described for explanation, rather than in order to limit the scope of the invention.Principle of the present invention is applicable to 1G, 2G, 4G, 8G, 10G and the optical fiber link of high bandwidth more.In addition, principle of the present invention can realize in light (for example laser) emitter/receiver of any form factor such as XFP, SFP and SFF, without limits.Said that principle of the present invention was not limited to optical transceiver environment fully.
Optical transceiver 100 utilizes receiver 101 from optical fiber 110A receiving optical signals.Receiver 101 is by being converted to light signal the effect that the signal of telecommunication plays optical-electrical converter.Receiver 101 offers post amplifier 102 with the signal of telecommunication that obtains.Signal after post amplifier 102 amplifies signal and will amplify offers external host 111, shown in arrow 102A.External host 111 can be any computing system that can communicate by letter with optical transceiver 100.External host 111 can comprise mainframe memory 112, and mainframe memory 112 can be volatibility or source of non-volatile memory.In one embodiment, optical transceiver 100 can be printed circuit board (PCB) or other components/chips in the main frame 111, though this is optional.Optical transceiver 100 also can receive the signal of telecommunication so that be sent on the optical fiber 110B from main frame 111.Particularly, laser driver 103 receives the signal of telecommunication, shown in arrow 103A, and drive reflector 104 (for example laser or light-emitting diode (LED)) with signal, described signal makes reflector 104 will represent the light signal of the information in the signal of telecommunication that is provided by main frame 111 to be transmitted on the optical fiber 110B.Therefore, reflector 104 is as electrical to optical converter.
The behavior of receiver 101, post amplifier 102, laser driver 103 and reflector 104 can dynamically change according to multiple factor.For example, variations in temperature, power fluctuation and feedback each can influence the performance of these parts.Therefore, optical transceiver 100 comprises control module 105, control module 105 can evaluate temperature and voltage condition and other running environment, and from post amplifier 102 (shown in arrow 105A) and laser driver 103 (shown in arrow 105B) reception information.This allows control module 105 to optimize the performance that dynamically changes, and when detection has dropout in addition.
Particularly, control module 105 can be offset these variations by the setting of regulating on post amplifier 102 and/or the laser driver 103 (also shown in arrow 105A and 105B).These are provided with and regulate is very desultory, needs just to carry out when such these adjustings because have only when temperature or voltage or other low frequency change make.Received power is the example of such low frequency change.
For example, simulation part 200A can comprise digital to analog converter, analog to digital converter, high-speed comparator (for example being used for event detection), the reseting generator based on voltage, voltage regulator, voltage reference, clock generator and other analog component.For example, except other potential parts that the ellipsis 211D by level represents, simulation part 200A comprises transducer 211A, 211B, 211C.In these transducers each can be responsible for measuring can be from the measured operational factor of control module 200, for example, and supply voltage and transceiver temperature.Control module also can receive external analog or the digital signal from other parts in the optical transceiver, these external analog or digital signal are indicated other measurement parameter, for example laser bias current, transmitting power, received power, laser wavelength, laser temperature and thermoelectric (al) cooler (TEC) electric current.Many such lines illustrate two outer lines 212A and 212B that are used to receive such external analog signal, although can be arranged.
Internal sensor can produce the analog signal of expression measured value.In addition, the signal that provides of outside also can be an analog signal.In this case, analog signal is converted into digital signal, thereby can be used for the numerical portion 200B of control module 200 so that further handle.Certainly, each analog parameter value can have its analog to digital converter (ADC).Yet, in order to keep chip space, can utilize single ADC, such as illustrated ADC 214, periodically each signal is sampled in the mode of circulation.In this case, each analogue value can be provided for multiplexer 213, and multiplexer 213 is once selected in the described analog signal one in the mode of circulation, so that sampled by ADC 214.Alternatively, multiplexer 213 can be programmed to allow analog signal to be sampled by ADC 214 with any order.
As previously mentioned, the simulation part 200A of control module 200 also can comprise other analog component 215, for example, digital to analog converter, other analog to digital converter, high-speed comparator (for example being used for event detection), reseting generator, voltage regulator, voltage reference, clock generator and other analog component based on voltage.
The numerical portion 200B of control module 200 can comprise timer module 202, and timer module 202 provides numerical portion 200B employed various timing signals.Such timing signal can comprise for example programmable processor clock signal.Timer module 202 also can be used as WatchDog Timer.
Also comprise two general processor 203A and 203B.The instruction of particular, instruction set is followed in processor identification, and general operation that can operative norm, such as displacement, branch, add, subtract, multiplication and division, boolean operation, compare operation or the like.In one embodiment, general processor 203A and 203B are 16 bit processors, and can similarly be constructed.The precision architecture of instruction set is inessential for principle of the present invention, because instruction set can be optimised according to specific hardware environment, and accurate hardware environment is inessential for principle of the present invention.
Internal controller system storage 206 (should not obscure mutually with external persistent memory 106) can be random access storage device (RAM) or nonvolatile memory.The visits that Memory Controller 207 is shared to controller system memory 206 each and host communication interface 204 among processor 203A and the 203B and external apparatus interface 205.In one embodiment, host communication interface 204 comprises serial interface controller 201A, and external apparatus interface 205 comprises serial interface controller 201B.This dual serial interface controller 201A and 201B can utilize two line interfaces such as I
2C or other interface are communicated by letter, as long as described other interface can be discerned by the communication module both sides.A serial interface controller (for example serial interface controller 201B) is a master unit, and another serial interface controller (for example serial interface controller 201A) is from parts.
I/O multiplexer 208 is with each I/O pin multiplexing of controller module 200 each parts in the controller module 200.This makes different parts dynamically to distribute pin according to the existing ruuning situation of controller module 200.Therefore, the input in the controller module 200 output node can be more than pin available on the controller module 200, thereby reduce the footprints of controller module 200.
Described concrete environment with respect to Fig. 1 and Fig. 2, should be appreciated that, this concrete environment just can adopt a kind of in the countless architectures of the principle of the invention.As previously described, principle of the present invention is not to be intended to be restricted to any specific environment.
Therefore, principle of the present invention relates to a kind of optical transceiver, and described optical transceiver records possible record position based on the input from host computing system with the operation information customization, and carries out one or more actions alternatively when record.Customization record allows the user to specify to write down which operation information, records information to what memory location, and run action whether during record.The user sends input from main frame, thereby what logger task indication wants.Optical transceiver responds this input by the logger task of carrying out this input appointment.
With reference to figure 3, the figure shows the flow chart of the method 300 of optical transceiver customization record operation information.This method can be by carrying out about Fig. 1 and the described optical transceiver environment of Fig. 2 or by other environment.At first, the microcode in the optical transceiver executive system memory (action 301).This microcode can be loaded into the system storage from main frame.Alternatively, microcode also can be loaded into the permanent memory from main frame, is loaded in the system storage then.
Microcode can comprise the various inputs of the logger task of wishing from the indication of main frame.For example, described input can be a record type identifier 310, and its sign is wanted the records what operation information.For example, the user may wish a recording light transceiver temperature information, and perhaps the user may wish to write down all operation informations.Alternatively, described input can be a log location identification 311, and its sign stores recorded information into what memory location.The user can wish to record a memory location or a plurality of memory location.In addition, described input also can be an action identifier 312, the action that its sign optical transceiver can be carried out when record.This input of three types can be respectively, with different combinations or be included in the microcode together.For example, the user may wish on whole operational information recordings to two memory location, but do not carry out any action when record.In this case, microcode will comprise record type identifier 310 and log location identification 311, and not comprise action identifier 312.As will be understood, the various combination of described input is producing great flexibility aspect the various logger tasks of control.
With reference to figure 1 and Fig. 2, optical transceiver 100 is carried out the microcode that receives from main frame.Particularly, processor 203A and 203B are loaded into microcode the controller system memory 206 from main frame.Wherein the controller system memory can be RAM, and it also can be processor, register, trigger or other memory device.For example, processor 203A and 203B can load by external host 111 and provide, pass through I
2C interface or other host interface of implementing are sent to the microcode of control module 105.For example, external host memory 112 can comprise the storehouse with different microcode functions.The user can select to move which microcode functions alternately and based on the logger task of hope with external host.Alternatively, processor 203 can load the microcode that has sent to permanent memory 106 in advance from main frame.In addition, external host 111 can be connected to other wide area network of internet or some, thereby allows processor 203 to obtain microcode from long-range source.This connection can realize by any standard the Internet or wan protocol.
Refer again to the method for Fig. 3, performed microcode makes optical transceiver based on the information (action 302) that writes down from the input of main frame reception about the ruuning situation of optical transceiver.As mentioned above, which type of logger task described input sign optical transceiver will carry out.
Refer again to Fig. 1 and Fig. 2, processor 203 is carried out microcode instructions, makes microcode form functional register in system storage 206 or additionally forms functional register.Described functional register have the right to visit optical transceiver for example from ADC 214 or from the various operational factors of outer lines 212A and 212B.
Register determines to write down which optical transceiver parameters based on the customization input from main frame, and described customization input can be corresponding to record type identifier 310, as previously described.External host 111 can be equipped with keyboard or other user interface, and it allows user's indication will write down which operational factor.For example, can indicate all operational factors all will be recorded from the input of main frame.Alternatively, can indicate the fluctuation of having only specific operational factor, for example temperature to be recorded from the input of main frame.
Register also can be instructed to based on result such as current running time of record data.Register also can receive the instruction of the condition that relevant when record data are provided.For example, if permanent memory is full greater than 40%, then record condition can specify all data to be recorded, if perhaps permanent memory 20% is full, then record condition can specify specific operational factor to be recorded.
The operation information that can be recorded can comprise statistical information, for example the sign of the sum of total run time, the average operating time between starting, the error situation that runs into, one or more error situations of running into, the classification of the number of the error situation that runs into being carried out at a plurality of type of errors, number of times that optical transceiver is activated or the like.Operation information also can write down the operational factor of measurement and general Measuring Time simply.Such operational factor can comprise for example laser wavelength approximation, laser temperature measured value, supply voltage measured value, transceiver temperature measured value, laser bias current measured value, thermoelectric (al) cooler (TEC) current measurement value, transmitting power measured value, received power measured value, acceleration measurement, peak accelerator measured value or the like.
Except being configured to write down specific operation information, optical transceiver 100 can also be configured to information stores that some or all the are write down record position to one or more appointments, such as mainframe memory 112, permanent memory 106 be positioned on the transceiver 100 or transceiver 100 beyond any other can the accessed record position.As mentioned above, different memory locations is specified by the customization input that receives from main frame, and described customization input can be corresponding to log location identification 311.For example, can indicate at least some recorded parts to be sent to mainframe memory 112 so that storage from the microcode of main frame 111, thereby allow user capture and the described information of assessment by SDA and scl line or other host communication interface of implementing.In addition, if main frame 111 is connected to internet or other wide area network, the information that then is recorded can utilize the internet of any standard or procotol to be uploaded to remote evaluation center from mainframe memory 112.In this case, if optical transceiver failure takes place, then various entries can be evaluated to determine to cause the possible cause of fault.For example, if write down an incident, it indicates optical transceiver and has experienced the peak accelerator that surpasses 20 times of acceleration of gravity (being represented as " G ' s " usually), can infer that then optical transceiver once fell.
In another embodiment, optical transceiver 100 can be configured at least some recorded parts are sent to transceiver persistent memory 106.If this permanent memory 106 is discrete modules, EEPROM module for example, then permanent memory 106 can be pulled out from optical transceiver 100, to assess its memory content.Alternatively, if optical transceiver has the exterior I/O interface that allows permanent memory 106 to be read, then permanent memory 106 can be evaluated under situation about not being removed from optical transceiver.
In another embodiment, optical transceiver 100 can be configured to all record data are sent to mainframe memory 112 and transceiver permanent memory 106.This will allow from two memory source any one to fetch the data of storage and the data of described storage are assessed, in case and an inefficacy in the memory source, this will create backup.Also control module 105 can be configured to whole record data are sent to mainframe memory 112 and the partial record data are sent to permanent memory 106.For example, permanent memory 106 can be used for for good and all storing the diagnostic message about optical transceiver 100.In case external host 111 is separated with optical transceiver 100, this will allow to analyze the possible cause of optical transceiver failure.As will be appreciated, have many operable record position combinations, the example that provides never is exclusive.
Except the operation information determining to write down with where write down these information, optical transceiver 100 can also be configured to when the information of determining is recorded, based on the action of carrying out one or more appointments from the input corresponding to action identifier 312 of main frame.For example, can indicate when information specific is recorded the self-test diagnostic program that control module 105 is carried out at the type of the information that is recorded from the microcode of main frame 111.For example, if detect unusual laser temperature, then can the recording laser actuator temperature and can carry out the self-test diagnosis of corresponding laser.Like this, can determine wrong or abnormal reason of any correspondence.
The example of the action that another one can be performed is " a microcode section paging "." microcode section paging " is restricted at environment make to need when so the action that externally transmits the microcode section back and forth between the main frame and transceiver.
When specific recording events took place, in response to this recording events, main frame 111 can be instructed to the microcode section is carried out paging.For example, if self-test diagnostic program above-mentioned is too big, to such an extent as to can not reside in controller system memory 206 or the permanent memory 106, then can indicate main frame 111 when information specific is recorded, the microcode section that will carry out the self-test diagnosis by SDA and scl line or other host communication interface sends to control module 105.Control module 105 can be carried out the microcode that receives from main frame 111 then.
Particularly, processor 203 is loaded into microcode the controller system memory 206 from main frame 111.Alternatively, if main frame 111 sends to microcode permanent memory 106 at first, then processor 203 can be loaded into the microcode that is stored in the permanent storage device 106 in the controller system memory 206.Processor 203 is carried out microcode, makes transceiver 100 carry out the diagnosis of appointment.
In case microcode is performed, if making, environment needs like this, then controller system memory 206 can send it back microcode mainframe memory 112.For example, after the self-test diagnostic program is by operation, this program is remained on transceiver 100 memories that will waste preciousness in controller system memory 206 or the permanent memory 106, particularly under the situation that program is only just moved when specific mistake takes place.Transceiver 100 can be configured to discern the end of self-test diagnostic procedure.When recognizing this process end, controller system memory 206 can pass through I
2C interface or other host interface of implementing send to mainframe memory 112 with microcode.Alternatively, main frame 111 can be configured to microcode is sent to mainframe memory 112.This process also can be applied to other microcode.
To a specific embodiment of the present invention be described with reference to the environment described in figure 1 and Fig. 2.Suppose that controller system memory 206 just carrying out microcode, the operating temperature that described microcode is formed between 70 ℃ and 80 ℃ is carried out the transceiver operation function.Utilize the present invention, can be on host computer 111 the designated recorder type identifier, drop to opening entry operational temperature information when being lower than 70 ℃ with convenient operating temperature.With this specific record type identifier together, can designated storage location, such as the specific memory location in the permanent memory 106.Also can specify the action that to carry out, such as the self-test of carrying out temperature controller by host computer 111 corresponding to recording events.This information can be by optical transceiver 100 inputs then.
As previously mentioned, control module simulation part 200A comprises transducer 211, and one of transducer 211 can be a temperature sensor.Suppose that operating temperature drops to below 70 ℃.Temperature sensor will detect this situation and transducer 211 will send to ADC 124 with the analog signal of representation temperature by multiplexer 213.ADC 214 can be digital signal with analog signal conversion and send it to processor 203.
Based on digitlization input from transducer, processor 203 will be determined that operating temperature has dropped to and be lower than 70 ℃ and make that controller 207 continues to receive operational temperature information and record operating temperature by transducer 211, with the position from host computer 111 downloads is original position, and it is stored in the permanent memory.If specified the self-test action, then processor 203 also with run time version to carry out self testing procedure.If obtain indication, then when self testing procedure was finished, host computer 111 just can pass through I
2C interface or other host interface of implementing obtain this information from processor 203.
In certain embodiments, control module 105 can comprise one or more default configurations, and described default configuration indication control module is carried out previously described various writing function, and need not the input of main frame 111.In such embodiments, can when making transceiver 100, determine default configuration.Microcode can be carried out by control module 105, and it causes the specified recording operation of default configuration.If desired, the user also can indicate main frame 111 to change default configuration.
Principle of the present invention provides the many benefits that surpass existing transceiver for optical transceiver.Particularly, the present invention allows end user's control of recording process.For example, the user can select to measure which transceiver parameters based on the microcode that register is carried out, and the information stores that will write down where.This provides flexibility for the user handles the information that is write down.Therefore, the user also can easily assess recorded data.In certain embodiments, can utilize internet or other wide area network to come Long-distance Control recording process and long-range evaluate recorded information.In another embodiment, the user can indicate some recorded informations promptly to store in the mainframe memory to store into again in the transceiver permanent memory.This has produced redundant backup, in case have one fault is arranged in two memories, the backup of described redundancy guarantees that the data of storage are protected.
In addition, the present invention allows the user to specify and carry out one or more actions when information is recorded.For example, in one embodiment, the user can indicate when information specific is recorded, and control module is carried out the self-test diagnostic program at the type that is recorded information.This allows more easily to determine mistake and fundamental cause thereof.In another embodiment, the user can indicate and carry out the outer microcode paging of transceiver.In this way, have only the microcode that more may be used to be loaded onto in the transceiver system memory.This allows to realize a large amount of microcode sections with a spot of transceiver system memory.Therefore, principle of the present invention has showed the marked improvement of art of optical transceivers.
