SFP56 50G PAM4光模块的传输距离数据
收藏资源简介:
为在5G前传高速互连中,确保模块在10km条件下满足FEC 容错能力,保障系统可靠性,需要测试光模块经过10km光纤回环后的误码性能。数据采集方式为:在温度(23±3)℃,湿度(55±5)%RH的洁净实验室环境下,将模块外接10km光纤进行回环测试,通过网络分析仪监测传输误码数,测试并记录纠后误码率。数据量为2MB。
To ensure optical modules meet the FEC error tolerance requirement under 10km conditions and guarantee system reliability in 5G fronthaul high-speed interconnection, it is necessary to test the bit error performance of the optical module after passing through a 10km optical fiber loopback. The data collection procedure is as follows: In a clean laboratory environment with a temperature of (23±3)°C and relative humidity of (55±5)%RH, connect the module to a 10km optical fiber for loopback testing, monitor the number of transmission errors via a network analyzer, and test and record the post-FEC bit error rate. The data volume is 2 MB.
