SFP 1.25G Tx1490/Rx1550 120Km LC Transceiver

Gearlink’s GCS9L0C45 SFP china transceiver is compatible with the Small Form
Factor Pluggable Multi-Sourcing Agreement (MSA). The transceiver consists of
five sections: the LD driver, the limiting amplifier, the digital diagnostic
monitor, the 1490nm DFB laser (the 1550nm DFB laser), and the APD/TIA. The
module data link up to 120km in 9/125um Single-mode fiber.

This transceiver meets the Small Form Pluggable (SFP) industry-standard package
utilizing an integral LC-Bi-directional and bidi fiber optical interface
connector. An enhanced Digital Diagnostic Monitoring Interface compliant with
SFF-8472 has been incorporated into the transceiver. It allows real-time access
to the transceiver operating parameters such as transceiver temperature, laser
bias current, transmitted optical power, received optical power, and
transceiver supply voltage by reading a built-in memory with an I²C interface.

The optical output can be disabled by an LVTTL logic high-level input of Tx
Disable, and the system also can disable the module via I²C. Tx Fault is
provided to indicate the degradation of the laser. Loss of signal (LOS) output
is provided to indicate the loss of an input optical signal of the receiver or
the link status with the partner. The system can also get the LOS (or
Link)/Disable/Fault information via I²C register access.
