Normal-temperature debugging system based on hot-pluggable optical module and normal-temperature debugging method

Abstract

The invention discloses a normal temperature debugging system based on a hot-pluggable optical module and a normal temperature debugging method based on the hot-pluggable optical module. The method comprises the following steps: setting a short-distance optical fiber transmission environment, and starting and initiating the parameter of the transmitting end of a to-be-debugged XFP (10 Gigabit Small Form Factor Pluggable) optical module; adjusting the APD (Avalanche Photo Diode) reverse bias voltage of the receiving end of the to-be-debugged XFP optical module to obtain error code rate information, and if the error code rate does not reach the minimum, writing an instruction of increasing the step length of the APD reverse bias voltage into the to-be-debugged XFP optical module; if the error code rate reaches the minimum, acquiring the APD reverse bias voltage when the error code rate is minimum; changing the set short-distance optical fiber transmission environment into a long-distance optical fiber transmission environment, adjusting the EA (Electro-Absorption) voltage of the to-be-debugged XFP optical module to obtain error code rate information, and if the error code rate does not reach the minimum, writing an instruction of reducing the step length of the EA voltage into the to-be-debugged XFP optical module; and if the error code rate reaches the minimum, acquiring the EA voltage when the error code rate is minimum. Through the application of the system and the method, the production first pass yield of the XFP optical module is increased.

Description

technical field [0001] The invention relates to optical communication technology, in particular to a normal temperature debugging system and a normal temperature debugging method based on a hot-swappable optical module. Background technique [0002] With the development of the optical communication industry, high-speed optical fiber transmission technology is developing in the direction of expanding single-wavelength transmission capacity, ultra-long-distance transmission and wavelength division multiplexing systems. In the ultra-long-distance optical communication system, the 1550 band with the smallest attenuation in the G652 fiber has been favored by everyone. However, there is a certain dispersion value in the 1550 band, which will expand the optical signal and increase the bit error rate. For 40km or 80km The performance of 10Gb / s data transmission has been affected. Therefore, in the production of XFP (10Gigabit Small Form Factor Pluggable) optical modules, an optical...

Problems solved by technology

Among them, if the EA voltage is too small, the optical power will decrease, and if the EA voltage is too large, the optical channel cost will increase

Therefore, when the optical channel cost test fails to meet the standard, it is necessary to re-adjust the EA voltage for normal temperature debugging, and then re-test the optical channel cost for the entire XFP optical module. The waste of a lot of manpower and material resources reduces the production throughput rate of XFP optical modules
