SFP 1.25G Tx1490/Rx1550 80Km LC Transceiver

Gearlink’s GCS7L0C45 SFP 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 PIN/TIA. The
module data link up to 80km in 9/125um Single-mode fiber.

This transceiver meets the Small Form Pluggable (SFP) industry-standard package
utilizing an integral LC-Bi-directional optical and sfp bidi multimode
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.
