The Gigabit Single-Mode Single Fiber (BiDi) SFP Optical Transceiver Module is designed to provide reliable, high-speed optical communication for Gigabit Ethernet and fiber networking applications. Utilizing advanced WDM (Wavelength Division Multiplexing) technology, the module transmits and receives data over a single strand of single-mode fiber, reducing fiber deployment costs while maximizing network efficiency.

Operating at 1.25Gbps, the module complies with IEEE 802.3z 1000Base-BX and SFP MSA standards. It is available in complementary wavelength pairs of TX1310nm/RX1550nm and TX1550nm/RX1310nm, supporting transmission distances of up to 5 kilometers over single-mode fiber.

The compact hot-pluggable SFP form factor enables easy installation and replacement without interrupting network operation. Integrated Digital Diagnostic Monitoring (DDM/DOM) allows real-time monitoring of optical power, module temperature, supply voltage, and laser bias current, helping administrators optimize network performance and simplify maintenance.

Manufactured with premium optical components and strict quality control, the module offers excellent signal stability, low bit error rate, and long service life. It is widely compatible with Ethernet switches, industrial switches, routers, media converters, OLTs, and optical communication equipment from major networking manufacturers.

Ideal for enterprise networks, FTTx deployments, security surveillance, industrial automation, campus networks, ISP infrastructures, and metropolitan fiber networks, this module provides a dependable and cost-effective optical connectivity solution.
