How to identify the quality of optical receiver module
An optical receiver module, how do we identify whether it is good or bad? Pinsignal will give you some judgment indicators. A high-quality optical receiver module can ensure the flexible operation of FTTH and provide convenience for subsequent management and expansion. The optical receiver module should comply with ANSI_SCTE 06 2009.ICE61000-4-3. EN 607286 Cable networks for television signals, sound signals and interactive services. Part6: Optical equipment services EN 607283 Cable networks for television signals, sound signals and interactive services. Part3: Active broadband equipment for cable services. and ensure that the optical module can accommodate a variety of original equipment. The manufacturers should be certified by CE, EMI, EMC, ROHS, etc. The interface and size of the modules can be customized. The optical receiver module should have WDM, AGC, AGC-offset, I2C functions, so that users can monitor the real-time parameters of the optical module. The specific parameters include the maximum working environment temperature of 85 degrees,5V working voltage, working current below 200mA, receiving optical power -15dBm~+2dBm, Surge>2KV, ESD>4KV, etc. In addition, it can also display the factory information and prompt alarm/warning. Before shipment, the optical receiver module needs to have test of S-parameter, CTB/CSO, CN, MER, C-suprious to ensure that the optical module has good quality, performance and compatibility, avoid network interruption, and save maintenance time and cost. It is recommended to ask the supplier before purchasing the optical modules. Checking the module surface for insert loss, return loss, and isolation loss. If there is obvious damage, the optical module may be defective or second-hand. It can be judged by after-sales service, the service life of the optical modules is ordinary about 3 years, so we should choose the suppliers with quality assurance when choosing optical modules. Pinsignal is the professional optical module manufacturers, provides 3-year warranty service. Above is the way to identify the quality of optical modules. As a professional optical module manufacturer, Pinsignal will conduct product appearance test, parameter test, compatibility and connectivity test and optical end face cleaning before leaving the factory to ensure that users get high-quality optical modules.
