In order to make the object, technical solutions and advantages of the present invention clearly, describe the present invention below in conjunction with the drawings and specific embodiments.
According to the definition of SFP-MSA association, on communication equipment, a typical optical module comprises transmitting element, receiving element and control unit totally 3 major parts, specifically as shown in Figure 1.
Wherein, as shown in Figure 1, the core of transmitting element is semiconductor laser, and it accounts for whole optical module about 60% power consumption, be very easy to affect by internal temperature, therefore, the control circuit of this part is also the most complicated, and the useful life of semiconductor laser is the shortest, just be equal to the useful life of optical module its useful life, therefore, in the management/control signal group of optical module, specialized designs 2 signals are transmitting element partial service: TX-disable and TX-fault.Here, TX-disable signal closes transmitting element for controlling, and TX-fault is used for when transmitting element part breaks down, by changing this signal condition, to the device management unit alarm in communication equipment.
As for receiving element and control unit, its as shown in Figure 1, all belong to conventional application circuit, job stability is high, and temperature influence is very little, repeats no more here.
Above the structure of optical module is analyzed.
In addition, in optical module, also have a typical signal, i.e. RX-LOS signal, its for represent communication module and do not receive light signal or receive light signal but the power of this light signal lower than the lowest power threshold value of setting.
Based on describing above; in the present invention; only do not use at communication equipment insertion optical module the problem such as such as wastes power resource, security risk brought during this optical module to solve; method provided by the invention makes full use of above-mentioned RX-LOS signal and TX-disable two signals carry out Based Intelligent Control to optical module; during to realize not using this optical module only inserting optical module; close the transmitting element in this optical module, reach and save electric energy and safeguard protection object.
Below method provided by the invention is described:
See the method flow diagram that Fig. 2, Fig. 2 provide for the embodiment of the present invention.In this flow process, need to arrange register in the device management unit periphery of communication equipment, wherein, this register can for the register designed with programmable logic device (CPLD), it can be connected on the local bus of device management unit, specifically optical module connection diagram as shown in Figure 3.
And, as shown in Figure 3, by the TX-disable signal of light module in communication equipment and RX-LOS signal corresponding with any two bits of described register respectively, in such as Fig. 3, TX-disable signal is corresponding with the second bit of register, and RX-LOS signal is corresponding with the first bit of register.In addition, as shown in Figure 3, the data signal line of optical module also communicates with the such as special chip of the correlation unit in communication equipment, and the process of this data signal line similarly to the prior art, repeats no more.
Based on the optical module connection diagram shown in Fig. 3, then as shown in Figure 2, method flow provided by the invention is:
Step 201, when communication device initiated, the bit that the TX-disable signal of device management unit control light module in communication equipment is corresponding is the first state value, to guarantee that the transmitting element of optical module is in closed condition.
Here, the startup of communication equipment can be warm start, also can be cold start-up.
Preferably, in the present invention, this first state value specifically can be 1, so, in this step 201, when communication device initiated, the bit that the TX-disable signal of device management unit control light module in communication equipment is corresponding is 1, to represent that the transmitting element of optical module is in closed condition.
As can be seen from step 201, in the present invention, when communication device initiated, on this communication equipment, the transmitting element of optical module is in closed condition, and this can ensure that optical module is in power saving and safe condition in the starting stage.
Step 202, after communication device initiated, when device management unit detects optical module in place, bit corresponding to the RX-LOS signal of this optical module is read with setpoint frequency, if the bit that RX-LOS signal is corresponding is the second state value, then perform step 203, if bit corresponding to RX-LOS signal is third state value, then perform step 204.
In this step 202, the second state value, third state value are different, and itself and the first above-mentioned state value are without any relation.
In addition, in this step 202, the bit that RX-LOS signal is corresponding is the second state value, then represent optical module do not receive light signal, or receive light signal but the power of this light signal lower than setting lowest power threshold value; And bit corresponding to RX-LOS signal is third state value, then represent the light signal that optical module receives power and is more than or equal to lowest power threshold value.Preferably, in the present invention, the second state value specifically can be 1, and third state value specifically can be 0.
Step 203, the bit maintaining the TX-disable signal of this optical module corresponding is the first state value.The read operation in step 202 can be returned afterwards.
Also namely, the transmitting element continuing to maintain this optical module is in closed condition, ensures that optical module is in power saving and safe condition.
Step 204, the bit revising the TX-disable signal of this optical module corresponding is the 4th state value, to start the transmitting element of this optical module, makes this optical module carry out normal light path connection.The read operation in step 202 can be returned afterwards.
In this step 204, the 4th state value is different from the first above-mentioned state value, but with the second above-mentioned state value, third state value without any relation.
This step 204 performs when the bit that RX-LOS signal is corresponding is third state value, be third state value based on the bit that RX-LOS signal is corresponding, expression optical module receives the light signal that power is more than or equal to lowest power threshold value, therefore, can find out, the present invention only optical module receive power be more than or equal to the light signal of lowest power threshold value time, just can start its transmitting element, carry out normal light path connection, and in other cases, such as when communication device initiated, or optical module does not receive light signal after communication device initiated, or receive light signal, but when the power of this light signal is lower than the lowest power threshold value set, close its transmitting element, this is in starting state compared to the transmitting element continuing to maintain optical module on this communication equipment after prior art on a communications device electricity, obviously power saving is reached, the object of safety.
It should be noted that, in step 203 and step 204 implementation, do not affect optical module and perform following process: optical module detects light signal, if it does not receive light signal, or receive light signal but the power of this light signal lower than setting lowest power threshold value, then arranging bit corresponding to its RX-LOS signal is the second state value, if and receive the light signal that power is more than or equal to lowest power threshold value, then arranging bit corresponding to its RX-LOS signal is third state value.
So far, the flow process shown in Fig. 2 is completed.
In the present invention, when communication equipment normally works, insert an optical module if new in this communication equipment course of normal operation, then perform the flow process shown in Fig. 4:
New flow chart when inserting optical module in the communication device works process provided for the embodiment of the present invention see Fig. 4, Fig. 4.As shown in Figure 4, this flow process comprises the following steps:
Step 401, by the TX-disable signal of this new insertion optical module and RX-LOS signal corresponding with any two idle bit positions of register in communication equipment respectively, and bit corresponding to the TX-disable signal arranging this optical module is the first state value, to guarantee that the transmitting element of optical module is in closed condition.
Step 402, when device management unit has detected that optical module newly inserts, bit corresponding to the RX-LOS signal of this new insertion optical module is read with setpoint frequency, if the bit that the RX-LOS signal of this new insertion optical module is corresponding is the second state value, then perform step 403, if the bit that the RX-LOS signal of this new insertion optical module is corresponding is third state value, then perform step 404.
Step 403, the bit maintaining the TX-disable signal of this new insertion optical module corresponding is the first state value.The read operation in step 402 can be returned afterwards.
Step 404, the bit revising the TX-disable signal of this new insertion optical module corresponding is the 4th state value, to start the transmitting element of this optical module, makes this optical module carry out normal light path connection.
It should be noted that, in step 403 and step 404 implementation, do not affect optical module and perform following process: optical module detects light signal, if it does not receive light signal, or receive light signal but the power of this light signal lower than setting lowest power threshold value, then arranging bit corresponding to its RX-LOS signal is the second state value, if and receive the light signal that power is more than or equal to lowest power threshold value, then arranging bit corresponding to its RX-LOS signal is third state value.
So far, the flow process shown in Fig. 4 is completed.Based on the meaning that above-described first state value represents to the 4th state value, can find out, in the present invention, from newly inserting optical module at communication equipment until device management unit detects the new time period of inserting before optical module, the transmitting element controlling this new insertion optical module is in closed condition, ensures that this new insertion optical module is in power saving and safe condition; And, even if device management unit detects newly insert optical module, if this new insert module does not receive light signal, or receive light signal but the power of this light signal lower than setting lowest power threshold value, also can close the transmitting element of this new insertion optical module, ensure that this new insertion optical module is in power saving and safe condition further; And if this new insert module receives the light signal that power is more than or equal to lowest power threshold value, then start its transmitting element, carry out normal light path connection, this does not delay new work of inserting optical module.
It should be noted that, in the present invention, determine whether to start the transmitting element of optical module adopting flow process shown in flow process shown in above-mentioned Fig. 2 or Fig. 4, may occur that the two ends communication equipment of Fiber connection is waited for mutually, the phenomenon that cannot connect in time, in order to avoid this phenomenon, below by flow process shown in Fig. 5, method provided by the invention is described in detail:
See the detail flowchart that Fig. 5, Fig. 5 provide for the embodiment of the present invention.As shown in Figure 5, this flow process can comprise the following steps:
Step 501, when communication device initiated, the bit that the TX-disable signal of device management unit control light module in communication equipment is corresponding is the first state value, to represent that the transmitting element of optical module is in closed condition; Or, in communication equipment course of normal operation during new insertion one optical module, by the TX-disable signal of this new insertion optical module and RX-LOS signal corresponding with any two idle bit positions of described register respectively, and bit corresponding to the TX-disable signal arranging this optical module is the first state value, to guarantee that the transmitting element of optical module is in closed condition.
Find out from step 501, flow process shown in Fig. 5 contain flow process shown in Fig. 2 situation and communication device initiated time situation, the situation that simultaneously also contains flow process shown in Fig. 4 i.e. new situation when inserting optical module in communication equipment course of normal operation.
Step 502, after communication device initiated, device management unit detects optical module in place, or, when device management unit has detected that optical module newly inserts, perform step 503.
For ease of describing, the optical module in place this detected below or the new optical module that inserts are collectively referred to as optical module 1.
Step 503, with the bit that the RX-LOS signal of setpoint frequency reading optical module 1 is corresponding, detecting this bit is the second state value or third state value, if the second state value, then performs step 504, if third state value, then performs step 510.
Step 504, the bit that the RX-LOS signal of detection optical module 1 is corresponding is whether the second state value maintains the first setting-up time continuously, if so, then performs step 506, if not, performs step 505.
Be the meaning that the second state value represents based on the bit value that RX-LOS signal is corresponding, then this step 504 is specially: the light signal do not received in the optical module 1 continuously very first time or receive light signal but optical signal power lower than lowest power threshold value, then perform step 506, otherwise, perform step 505.
Step 505, the bit that the TX-disable signal of maintenance optical module 1 is corresponding is the first state value.Return step 503.
Step 506, bit corresponding for the TX-disable signal of optical module 1 is initiatively revised as the 4th state value by device management unit, and in the second setting-up time, maintain bit corresponding to this TX-disable signal be the 4th state value always.
This step 506, why initiatively bit corresponding for the TX-disable signal of optical module 1 is revised as the 4th state value, object makes optical module 1 normally work exactly, carries out normal light path and connects exploration, waits for, cannot set up light path connection phenomenon to avoid opposite end.But waste resource without avoiding, it is free restriction that this light path connects exploration, namely only carries out in the second setting-up time.
Wherein, the second setting-up time and above-described first setting-up time have nothing to do, and it is all arranged according to practical experience situation.In this two setting-up time, if optical module 1 does not receive light signal, or receive light signal but the power of this light signal lower than setting lowest power threshold value, then still maintaining bit corresponding to its RX-LOS signal is the second state value, if and receive the light signal that power is more than or equal to lowest power threshold value, then revising bit corresponding to its RX-LOS signal is third state value.
Present inventor, through repeatedly testing, works out the value of above-mentioned first setting-up time and the second setting-up time, specifically as shown in table 1:
Table 1
| Sequence number | First setting-up time | Second setting-up time |
| 1 | 30 seconds | 10 seconds |
| 2 | 60 seconds | 10 seconds |
| 2 | 120 seconds | 10 seconds |
| 3 | 180 seconds | 10 seconds |
Step 507, device management unit detects bit corresponding to the RX-LOS signal of optical module 1, if this bit is still the second state value, then performs step 508, if be third state value, then execution step 510.
Step 508, detects the light path whether reaching setting and connects the exploration time, if so, perform step 509, otherwise, return step 507.
Wherein, the light path connection exploration time of setting can be arranged according to practical experience situation, can have nothing to do with the first above-mentioned setting-up time, the second setting-up time.
Step 509, stops light path connecting and sounds out, and determines that this optical module 1 is only insert but the optical module do not used, and bit corresponding for the TX-disable signal of optical module 1 is revised as the first state value.
Step 510, the bit revising the TX-disable signal of this optical module 1 corresponding is the 4th state value, to start the transmitting element of this optical module 1, makes this optical module 1 carry out normal light path connection.
So far, the flow process shown in Fig. 5 is completed.As can be seen from flow process shown in Fig. 5, this flow process specifically can be the four-stage shown in Fig. 6, specifically as shown in Figure 6.
It should be noted that, for only inserting but the optical module do not used of being determined by step 509 in flow process shown in Fig. 5, when certain is ready at all times to use this optical module afterwards, just need manual intervention to change the state of this optical module, to start the transmitting element of this optical module, this optical module is made to carry out normal light path connection.Wherein, manual intervention can be the direct plug of site administrator once this optical module, make it process according to the new flow process inserting optical module, or start the transmitting element of this optical module by network management command direct control, make this optical module carry out normal light path connection.
Also need illustrate time, in the present invention, if subsequent optical module 1 is still inserted on a communications device but do not used, or use flow process shown in Fig. 5 to reach the closedown of the transmitting element of optical module 1, no longer power consumption and the object of safety, and prior art is by continuous drain.
For the first setting-up time under sequence number in table 11 and the second setting-up time, if it is 60 minutes that the light path of then setting connects the exploration time, then conventionally scheme, the transmitting element of optical module 1 was in starting state in 60 minutes always, and based on flow process shown in Fig. 5, the time that the transmitting element of optical module 1 is in starting state is:
10(second) * 60 minutes (these 60 minutes=60 seconds * 60 seconds)/(the first setting-up time 30 seconds+the second setting-up times 10 seconds)=900 seconds, namely 15 minutes is 1/4 of the total power consumption of optical module in prior art 1 transmitting element.
