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.

3Pages 2.3 Host Board Power Supply Requirements
The host board is required to provide a regulated and filtered power supply of 3.3V +/-
5% for the GO2921B via the on board SFP connector. Figure 2-3 shows the
recommended board supply filtering. When the host board is loaded with a resistive
load in place of the SFP module and sourcing the maximum rated current, the
peak-to-peak power supply noise measured on the SFP connector should comply to
Table 2-2.
