Description

The GCS-B3425-B3425-20C is compatible with the Compact Small Form- Factor Pluggable (CSFP) Multi-Source Agreement (MSA) option 2, provides 2.488Gbps and 20km transmission over single-mode fiber (SMF) using a wavelength of 1310nmTx/1490nmRx via an LC connector.It is with the SFP 20-pin connector to allow hot plug capability. Digital diagnostic functions are available via an I2C interface as specified in the MSA SFF-8472.

The transceiver consists of 2-channel bi-directional optical transceiver unit with five sections: the LD driver, the limiting amplifier, the digital diagnostic monitor, type of laser (the DFB laser) and the PIN photo-detector.

The optical output can be disabled by a TTL logic high-level input of Tx Disable, and the system also can disable the module via I2C. Tx Fault is provided to indicate that degradation of the laser. Loss of signal (LOS) output is provided to indicate the loss of an input optical signal of receiver or the link status with partner. The system can also get the LOS (or Link)/Disable/Fault information via I2C register access. Conventional SFP will function when plugged into a C-SFP socket, at the same time no damage to C-SFP and host board if C-SFP module is plugged into a conventional SFP socket
