SFP 1.25G Tx1310/Rx1490 10Km LC Transceiver

Gearlink’s SFP-GE-BX SFP transceiver is compatible with the Small Form Factor Pluggable Multi-Sourcing Agreement (MSA). The 1310nm 1490nm sfp transceiver consists of five sections: the LD driver, the limiting amplifier, the digital diagnostic monitor, the 1310nm FP laser(the 1490nm DFB laser), and the PIN/TIA. The module data link up to 10km in 9/125um Single-mode fiber.

This sfp 1310 1490 transceiver meets the Small Form Pluggable (SFP) industry-standard package utilizing an integral LC-Bi-directional optical/sfp bidi 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.

SFP 1310 1490 Features

Simple to Use: Simple installation, plug and play, and fully hot-pluggable. With 1.25G SFP 1310 1490 ports, it is commonly used for the fiber switches, routers, NICs, servers, as well as other fiber optic equipment.

Superior DDM Function- DDM helps in monitoring critical information about the status of the transceivers' transmission and reception signals in real-time to identify potential issues.

How to pair single-mode single-fiber optical transceivers?

The single-fiber optical SFP transceiver realizes data transmission through one fiber core. Data transmission and reception are realized through different optical wavelengths in one optical fiber. Single-fiber optical transceiver s are generally used in pairs. The A/B side parameters are reversed. The A/B side parameters are reversed. Example A terminal optical transceiver (Tx 1310nm/Rx 1490). B-end optical transceiver (Tx 1490nm/Rx 1310)
