The Gigabit Single-Mode Single Fiber (BiDi) SFP Optical Transceiver Module is a compact, hot-pluggable optical transceiver designed for high-speed Gigabit Ethernet and fiber communication systems. Utilizing BiDi (Bidirectional) WDM technology, the module enables simultaneous transmission and reception over a single strand of single-mode fiber, reducing fiber deployment costs while maximizing infrastructure efficiency.
Operating at a data rate of 1.25Gbps, the module complies with IEEE 802.3z Gigabit Ethernet and SFP MSA standards. It is available in complementary wavelength pairs of TX1310nm/RX1550nm and TX1550nm/RX1310nm, providing stable optical communication over distances of up to 3km.
The module features a standard LC simplex connector, digital diagnostic monitoring (DDM/DOM) support, and hot-swappable functionality, allowing quick installation and maintenance without interrupting network operation. Manufactured with premium optical components, it offers excellent signal stability, low insertion loss, and superior anti-interference performance.
Designed for wide compatibility, the transceiver works seamlessly with Ethernet switches, industrial switches, media converters, routers, optical transmission equipment, IP surveillance systems, and data communication devices from most mainstream networking brands.
Its low power consumption, industrial reliability, and compact SFP form factor make it an ideal choice for enterprise networks, FTTx deployments, intelligent transportation systems, campus networks, industrial automation, and security monitoring applications.
