GO2921B

Description


The GO2921B is an optical transceiver module designed to transmit and receive electrical and optical serial digital signals as defined in SMPTE 297-2006. The GO2921B 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 GO2921B contains a PIN photodiode receiver and a 1310nm Fabry-Perot laser transmitter designed to provide error-free transmission of signals from 50Mbps to 3Gbps over single mode fiber (9/125). It is also hot-pluggable.

The GO2921B provides extensive operational status monitoring through an I²C interface. Input optical power is monitored in the receiver; output optical power and bias current are monitored in the transmitter. Other operating conditions, such as power supply and operating temperature, are also monitored. If a monitored parameter falls outside the pre-defined range, an alarm flag for the parameter is raised.
