SFP 1.25G Tx1550/Rx1310 20Km LC Transceiver

Gearlink’s SFP-GE-BX 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 1310nm FP laser(the 1550nm DFB laser), and the PIN/TIA. The module data link up to 20km in 9/125um Single-mode fiber.

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

What are the core components of the single-fiber optical transceiver ?

The core components of a single-fiber optical transceiver  are roughly similar to those of a dual-fiber optical transceiver . The main difference is that the single-fiber optical transceiver  has a BOSA core device, which integrates light emitting and receiving light, and the price is higher than TOSA and ROSA. Because the cost of a single-fiber optical transceiver  is higher than that of a dual-fiber optical transceiver .

How are optical transceiver s used in monitoring systems?

Everyone knows that the transmission distance of the network cable is only 100 meters, and the distance between the surveillance camera and the surveillance center is generally no less than 100 meters. At this time, a relay device fiber optic transceiver is needed to do a relay. The fiber optic transceiver is connected to the network cable of the camera, an optical transceiver  is inserted into the optical port to connect to the optical transceiver  on the switch, and the electrical port of the switch is connected to the video recorder. Then project the final picture to the monitor.
