Described in embodiment do not represent and the consistent all embodiments of the present invention.On the contrary, they be only with it is such as appended
The example of the consistent apparatus and method of some aspects be described in detail in claims, the present invention.
For when the pin on front optical module is more, space-consuming is relatively large, it is impossible to which meeting an OLT host device can
Carry the problem of more kinds of OLT optical modules are required.The embodiments of the invention provide a kind of method of OLT optical modules pin multiplexing,
Device and OLT optical modules, its central principle is：By hard Disable signals, into pin is received all the way with Trigger signal fuseds,
Distinguished by software and realize two kinds of functions of Trigger/Disable, Fig. 2 is OLT optical modules provided in an embodiment of the present invention
The schematic diagram that Trigger signals and hard Disable signal multiplexings pin are connected with OLT host devices, and then utilize the above method
OLT host devices can be made to save signal pin all the way.
Based on above-mentioned principle, method and apparatus provided in an embodiment of the present invention are situated between in detail below in conjunction with accompanying drawing
Continue.Fig. 3 is the schematic flow sheet of the method for the OLT optical module pin multiplexings that the embodiment of the present invention one is provided.As shown in figure 3, should
Method specifically includes following steps：
Step S110：Detect the signal conversion instruction from optical line terminal OLT host device.
Specifically, OLT host devices can be changed by I2C to the Disable/Trigger signals that harden under OLT optical modules
Instruction, informs its signal that will be sent by signal pin to OLT optical modules.Then, OLT optical modules are by detecting above-mentioned letter
Number conversion instruction, to control the function of its signal pin.
Further, the signal conversion instruction that OLT host devices can be issued sends into OLT optical modules default post
The signal conversion instruction that processor in storage, OLT optical modules is stored in the register by reading carries out follow-up signal
Control operation.Wherein, above-mentioned default register can be the reservation register of agreement, such as 8472 protocol devices address 0xA2 skews
Address 0x6F registers, using its bit0 instruction control bit as the hard Disable of Trigger/, such as concurrently set bit0 and put one
When represent that the signal that receives is Trigger signals, when bit0 zero setting represents that the signal received is then hard Disable signals.
Step S120：If the signal conversion instruction includes first state data, by the multiplexing of the OLT optical modules
The signal that pin is received turns off Disable signals as laser firmly.
For example, OLT host devices write-in 0x6F registers are set to zero for the status data of 0x00, i.e. bit0, then it represents that
OLT host devices will be hardened down Disable signals, and the signal for now then receiving the multiplexing pins of OLT optical modules is switched to
Turn off Disable signals firmly as laser to use, i.e., OLT optical modules can be simultaneously by hard Disable signals and soft Disable
Signal is controlled, and the state is named as the first Disable states by the present embodiment.
Fig. 4 is that signal control process when OLT optical modules provided in an embodiment of the present invention are in the first Disable states is shown
It is intended to.As shown in figure 4, specifically including following steps：
Step S121：Detect the level state of the multiplexing pins of the OLT optical modules.
Because the hard Disable signals that OLT optical modules are sent generally control to swash in optical module by low and high level signal
The on off state of light device, if for example, the pin for receiving Disable signals is in high level state, then it represents that laser drives
Circuit will turn off output to the bias current of corresponding laser and modulation electric current, to close laser, on the contrary, then opening laser
Device.
Step S122：If the multiplexing pins are the first level state, swashing in the OLT optical modules is closed in control
Light device.
First level state of multiplexing pins is defined as high level state by the present embodiment, if corresponding current multiplexing is drawn
Pin is high level state, then OLT optical modules control its internal Disable signal outputs pin to be high level, and OLT is stated to close
Laser in optical module.
Step S123：If the multiplexing pins are second electrical level state, according to from the soft of the OLT host devices
Disable signals control the on off state of laser in the OLT optical modules.
According to the definition in step S122, corresponding multiplexing pins are that second electrical level state is then low level state, now
Laser is opening under control of hard Disable signals, and the switch of laser will also pass through by OLT host devices
The control for the soft Disable signals that I2C is issued, it is specific as follows：
1) whether soft Disable signal of the detection from the OLT host devices is to open laser signal.
If 2) the soft Disable signals from the OLT host devices is open laser signal, by Disable
Signal output pin is set to low level signal, to control laser to be in opening.
3) otherwise, then Disable signal output pins are set to high level signal, to close laser, i.e. OLT optical modes
Block does not retransmit descending optical signal.
Step S130：If the signal conversion instruction includes the second status data, by the multiplexing of the OLT optical modules
The signal that pin is received triggers Trigger signals as light signal strength.
For example, OLT host devices write-in 0x6F registers are set to one for the status data of 0x01, i.e. bit0, then it represents that
OLT host devices will issue Trigger signals, so, OLT optical modules just can detect the signal that is sent by multiplexing pins Lai
Determine whether that ONU sends upward signal.Specifically, by being provided with Trigger signal edge detections electricity in OLT optical modules
Road, when Trigger signal edge detections electric circuit inspection to trigger signal produces trailing edge (or rising edge), i.e. Trigger letters
Number level state switching when, then OLT optical modules think to have that ONU sends upward signal, will to carry out luminous power sampling accurate
It is standby.
Certainly, the signal conversion instruction in the present embodiment is not limited to only with 0 and 1 two status data of bit0 come table
Show, the form of other register datas position can also be used, furthermore it is also possible to which the status data switched with indication signal combines it
The form of its data.
Further, during the present embodiment gives OLT optical modules entrance reception Trigger signals, light is controlled
The method of laser switch state in module.
Fig. 5 is signal control when OLT optical modules provided in an embodiment of the present invention are in second and the 3rd Disable states
Process schematic.As shown in figure 5, specifically including following steps：
Step S131：Detect the current level state of the multiplexing pins of the OLT optical modules.
Specifically, the signal of the multiplexing pins reception of the OLT optical modules is being triggered into Trigger as light signal strength
Before signal, the current level state of the multiplexing pins of OLT optical modules is detected, if the first level state, then into step
S132, if second electrical level state, then into step S133.
Step S132：If the current level state of the multiplexing pins is the first level state, Trigger is being received
In signal process, the laser in the OLT optical modules is controlled to remain turned-off.
First level state of multiplexing pins is defined as high level state by the present embodiment, if corresponding current multiplexing is drawn
Pin is high level state, then when illustrating to be switched to Trigger states by hard Disable, and OLT host devices, which are in, closes laser behaviour
Make, then control the laser in the OLT optical modules to remain off in Trigger signal process is received, the present embodiment
The state is defined as the 2nd Disable states, i.e., during Trigger signals are received using multiplexing pins, OLT optical modes
Block controls its internal Disable signal outputs pin to be high level state all the time.
Step S133：If the current level state of the multiplexing pins is second electrical level state, Trigger is being received
In signal process, laser in the OLT optical modules is controlled according to the soft Disable signals from the OLT host devices
On off state.
According to the definition in step S132, corresponding multiplexing pins are that second electrical level state is then low level state, and then
If current multiplexing pins are high level state, when illustrating to be switched to Trigger states by hard Disable, OLT host devices
In laser operation is opened, then in Trigger signal process is received, according to the soft Disable from the OLT host devices
Signal controls the on off state of laser in the OLT optical modules, and the state is defined as the 3rd Disable shapes by the present embodiment
The switch of state, i.e. laser is only controlled by soft Disable signals.Wherein, specific control process may be referred to step S120
In, this is no longer going to repeat them for the present embodiment.
As seen from the above-described embodiment, the method for a kind of OLT optical modules pin multiplexing provided in an embodiment of the present invention, according to next
From the signal conversion instruction of optical line terminal OLT host device, OLT optical module pins are switched into the hard Disable signals of reception
State receives Trigger signal conditions, and then realizes that hard Disable and Trigger signals can share pin all the way, compares
The hard Disable and Trigger signals two-way pin control of traditional optical module, the embodiment of the present invention can be saved in hardware design
Save signal pin all the way, so can meet an OLT host device can light carry the demand of polytype module.
Further, the present embodiment is additionally provided before multiplexing pins switch to Trigger states, by detecting that multiplexing is drawn
The current level state of pin is opened the light the control method of state with determining laser, and then realizes that OLT is receiving Trigger signals
During, also realize effective control to laser switch state in OLT optical modules.
During being connected due to OLT optical modules with OLT host devices communications, do not only have the reception of its multiplexing pins and come from
The signal of OLT host devices, believes while OLT host devices can also be handed down to various controls by I2C buses to OLT optical modules
Number, and I2C control signals have highest priority orders, therefore OLT optical modules are performing the switching of multiplexing pins function
During if receiving related I2C control instructions simultaneously, then multiplexing pins function switching process will be interrupted, wait to hold
Go rear I2C control instructions, be further continued for performing the process of multiplexing pins function switching.But above-mentioned multiplexing pins function switching
After process is interrupted, it is easy to the problem of disorderly multiplexing pins function switching, handoff error occur.In view of the above-mentioned problems, this hair
The method that bright embodiment additionally provides another OLT optical modules pin multiplexing.
Fig. 6 is the schematic flow sheet of the method for the OLT optical module pin multiplexings that the embodiment of the present invention two is provided.Such as Fig. 6 institutes
Show that this method specifically includes following steps：
Step S210：Detect the signal conversion instruction from optical line terminal OLT host device.
The present embodiment identifies the testing result to signal conversion instruction using temporary variable data Newstate.Specifically,
If signal switching command OLT host devices will issue Trigger signals, Newstate is designated 1, if on the contrary,
Signal switching command OLT host devices will harden down Disable signals, then Newstate is designated into 0.
Corresponding, OLT optical modules are also with the current state of historical variable data OldState storages multiplexing pins.Specifically
, if the state in reception Trigger semiotic functions of multiplexing pins currently, 1 is designated by OldState, on the contrary,
If the state in the hard Disable semiotic functions of reception of multiplexing pins currently, 0 is designated by OldState.
If the signal conversion instruction includes first state data, step S220 is performed；If the signal conversion instruction
Comprising the second status data, then step S240 is performed.
Step S220：If the signal conversion instruction includes first state data, the OLT optical modules storage is detected
Current status data whether matched with the first state data.
In conjunction with the embodiments one, if signal conversion instruction is set to comprising the status data of first state data, i.e. bit0
Zero, then illustrate that OLT host devices will harden down Disable signals, it is corresponding that Newstate is designated 0, and detect OLT
Whether the current status data OldState of optical module storage is also 0.If OldState is 1, i.e., both are inconsistent, not phase
Match somebody with somebody, then continue executing with step S23O；On the contrary, if OldState is 0, both are consistent, then illustrate that multiplexing pins are currently also located
It is identical with the state that will switch in the state for receiving hard Disable semiotic functions, status switching instruction is then no longer performed,
And then the number of times of state switching can be reduced, it can not only prevent the process that multiplexing pins function switches by I2C control instructions
Interrupt, the problem of handoff error occur, the time of function switching can also be saved, accelerate signal transacting and carry out.
Step S230：If the current status data of the OLT optical modules storage is mismatched with the first state data,
The signal that then multiplexing pins of the OLT optical modules are received is believed by being switched to as Trigger signals as hard Disable
Number.
If both mismatch, illustrate that multiplexing pins are currently at the state for receiving Trigger semiotic functions, then will be multiple
The signal received with pin is entered by being switched to as according to Trigger signal transactings as according to hard Disable signal transactings
Enter the first Disable functional statuses, meanwhile, also OldState is updated to 0 to record current functional status.
Step S240：If the signal conversion instruction includes the second status data, the OLT optical modules storage is detected
Current status data whether matched with second status data.
In conjunction with the embodiments one, if signal conversion instruction is set to comprising the status data of the second status data, i.e. bit0
One, then illustrate that OLT host devices will issue Trigger signals, it is corresponding that Newstate is designated 1, and detect OLT light
Whether the current status data OldState of module storage is also 1.If OldState is 0, i.e., both are inconsistent, not phase
Match somebody with somebody, then continue executing with step S25O；On the contrary, if OldState is 1, both are consistent, then illustrate that multiplexing pins are currently also located
It is identical with the state that will switch in the state for receiving Trigger semiotic functions, then no longer perform status switching instruction.
Step S250：If the current status data of the OLT optical modules storage is mismatched with second status data,
The signal that then multiplexing pins of the OLT optical modules are received is believed by being switched to as hard Disable signals as Trigger
Number.
If both mismatch, illustrate that multiplexing pins are currently at the state for receiving hard Disable semiotic functions, then will
The signal that multiplexing pins are received as according to hard Disable signal transactings by switching to as according to Trigger signal transactings, together
When, also OldState is updated to 1 to record current functional status.
It should be noted that the present embodiment is not limited to current status data and the signal switching that OLT optical modules are stored
Illustrate that both match when the representative status data of instruction is consistent, can also be included with the two or corresponding instruction
The relations such as information illustrate its matching relationship, and this is no longer going to repeat them for the present embodiment.
Further, before signal conversion instruction of the detection from optical line terminal OLT host device, OLT optical modules
After power-up routine startup optimization, the signal acquiescence that the multiplexing pins of the OLT optical modules are received is believed as hard Disable
Number, that is, give tacit consent to its laser after electricity in the first Disable states, module and just enter working condition, and according to follow-up letter
Number conversion instruction switches the function of multiplexing pins.
