It is limited.On the contrary, these embodiments are provided to facilitate a more thoroughly understanding of the present invention, and can be by the scope of the present disclosure
It is fully disclosed to those skilled in the art.
Embodiment one
In order to solve test instability problem existing in the prior art, the embodiment of the present invention provides a kind of connecing for optical module
Acceptance Tests method, as shown in Figure 1, comprising the following steps:
Step S101, host computer send setup test instruction to light source board.
Step S102, the controller of light source board send enable end by preset rules for the optical module of light source board and provide height electricity
It is flat to represent the presence or absence of setup test instruction light sequence to generate, and there is unglazed sequence to be sent to through the optical path of optical attenuator this
ONU carries out test preparation.
Specifically, the controller of light source board provides height electricity by preset rules for the transmission enable end of the optical module of light source board
It is flat to represent the presence or absence of setup test instruction light sequence to generate.According to optical module related electric interface protocol INF-8074 it is found that
Sending enable end may be implemented shutdown emission function, high level or vacantly be it is effective, now using this pin function, generation shaped like
" having light-unglazed ,-having light-unglazed-has light-unglazed, and-having light-unglazed-has light-unglazed-having light-unglazed-have light-it is unglazed-have light-
Have light " the presence or absence of light sequence, with this represent setup test instruction.

Circuit control optical attenuator provides the light for meeting default optical power for ONU.
Step S105, ONU carry out optical power calibration using received light or LOS point is arranged.
For step S103-S105, due to, without configuration information, being needed in the main control chip of the BOB optical module of initialization
It is carried out receiving optical power calibration and setting LOS point.
Specifically, the method for carrying out received optical power calibration may include the following contents:
(1) PC control light source board sends the light of regulation power, and the transmitting optical power of light source board is usually fixation, than
Such as -5dBm, setting optical attenuator is undamped at this time, and the light of ONU reception -5dBm, light-receiving secondary module (ROSA) is by this -5dBm's
Light changes into corresponding electric current, and from RSSI, (Received Signal Strength Indication received signal intensity refers to
Showing) pin exports to the main control chip of BOB optical module, and which is converted into voltage value for this current value, then passes through ADC
(Analog-to-Digital Converter, analog-digital converter) is converted into digital voltage value, such as 1.2V, and finally record connects
The corresponding relationship of the 1.2V voltage of -5dBm light and output received.
(2) host computer or light source board press preset rules by circuit control optical attenuator, provide satisfaction default light function for ONU
The light of rate, such as control optical attenuator are -15dBm, then OUN received optical power is -20dBm.Likewise, this optical power is converted
At digital voltage value, such as 0.5V, and record the corresponding relationship of the 0.5V voltage of received -20dBm light and output.
(3) equation shaped like " y=kx+b " is obtained according to two groups " optical power-ADC voltage values " in (1), (2), wherein
X is ADC voltage value, and y is optical power, and k, b are that the accurate optical power of BOB optical module progress reports required parameter, saves the ginseng
Number.So far, the calibration of received optical power is completed.Future in the actual use of ONU, can use parameter k, b and output ADC
Voltage value calculates the optical power of input, completes optical power further according to SFF-8472 protocol requirement and reports.
Furthermore it is also possible to which LOS point is arranged, for example LOS (loss of signal alarm) point is arranged in -30dBm, then completes
(1) after, the transmitting optical power of plate is usually that fixation, such as -5dBm, then host computer or light source board control optical attenuator produce
The decaying of raw -25dBm.The optical power of OUN reception -30dBm, and this optical power is converted to digital voltage value (such as 0.2V),
Finally recorded this value as LOS point.In future, when the digital voltage value of OUN output is less than 0.2V, optical module will be produced
Raw LOS alarm.
In the present embodiment, host computer is not connected directly using RJ45 or RS232 and ONU, is avoided that since cable exists always
Unstable situation is tested caused by change or poor contact, improves testing efficiency.In addition, the controller of the application light source board is pressed
Preset rules send enable end for the optical module of light source board and provide low and high level to generate and represent the presence or absence of setup test instruction light
Sequence, and having unglazed sequence to be sent to the method that ONU carries out test preparation through the optical path of optical attenuator this is existing test
Method provides new resolving ideas.It should be understood that test method disclosed in the present embodiment can be applied to based on BOB technology
Optical module, also can be applied to other optical modules.
