1.25 Gbps SM SF 120 km LC BiDi SFP Transceiver – Long-Reach High-Speed Optical Networking Solution
The 1.25 GBPS SM SF 120km LC BIDI SFP Transceiver (WDM) is a high-performance, cost-efficient optical module engineered for long-distance, high-speed data communication. Designed to operate over single-mode fiber (SMF) at distances up to 120 kilometers, this transceiver is the ideal solution for metro networks, telecom backbone connections, enterprise long-haul deployments, and fiber-to-the-x (FTTx) infrastructure.
Using Wavelength Division Multiplexing (WDM) technology, this bidirectional (BiDi) transceiver can transmit and receive signals over a single strand of optical fiber, significantly reducing fiber cabling requirements. It utilizes two wavelengths—typically 1490nm for transmit (TX) and 1550nm for receive (RX) or vice versa—to achieve full-duplex communication.
This model is compliant with the IEEE 802.3z Gigabit Ethernet standard and the SFP Multi-Source Agreement (MSA), ensuring interoperability with a wide range of networking equipment such as switches, routers, and media converters.
