GO2920

The GO2920 is a dual channel optical receiver module designed to convert optical serial digital signals to electrical serial digital signals as defined in SMPTE 297-2006. The GO2920 is specifically designed for robust performance in the presence of SDI pathological patterns for SMPTE 259M, SMPTE 344M, SMPTE 292M and SMPTE 424M serial rates.
The GO2920 contains two independent optical receivers. Each receiver is designed to provide error-free reception of signals from 50Mbps to 3Gbps with up to 30km single mode fiber (9/125) when used with the GO2922-3131CM. A maximum distance of 10km is achievable under worst case conditions and 3Gbps pathological. The GO2920 is also hot-pluggable.
The GO2920 provides extensive operational status monitoring through an I2C interface. For each receiver channel, input optical power is monitored. Other operating conditions such as supply voltage and operating temperature are also monitored. If a parameter monitored is outside the pre-defined range, the alarm flag associated with the parameter will be raised.
