1.25 Gbps SM SF 40 km SC BiDi SFP Transceiver 1310/1550 – Reliable and Efficient Single-Fiber Networking Solution

The 1.25 Gbps Single Mode Single Fiber (SM SF) 40 km SC BiDi SFP Transceiver (1310/1550 nm) is a high-performance optical module designed for long-distance, cost-effective fiber optic communication. Engineered with Wavelength Division Multiplexing (WDM) technology, this BiDi (Bidirectional) transceiver enables the simultaneous transmission and reception of data through a single strand of optical fiber, significantly reducing infrastructure costs and simplifying deployment.

Operating at a transmit wavelength of 1310 nm and receive wavelength of 1550 nm, this compact SFP module is ideal for Gigabit Ethernet, Fiber Channel, FTTH, and other optical transmission applications requiring up to 40 km reach. Built with an SC simplex connector, it offers easy installation and a reliable interface for telecom, enterprise, and industrial network environments.

✅ Key Features

🔁 Bidirectional Transmission Over a Single Fiber

Using WDM technology, this transceiver can send and receive signals at different wavelengths (1310 nm Tx / 1550 nm Rx) over a single strand of fiber, effectively doubling the fiber utilization and reducing costs without compromising data integrity or speed.

🚀 40 km Transmission Range

The device supports long-distance communication of up to 40 kilometers over single-mode fiber (SMF), making it suitable for medium-range network deployments like inter-building connections, metro access, and telecom backbone networks.

⚙️ Industry Standards Compliance

Fully compliant with IEEE 802.3z, SFP MSA (Multi-Source Agreement), and SFF-8472 standards, this transceiver guarantees interoperability with a wide range of switches, routers, and optical networking equipment from multiple vendors.

💡 SC Simplex Connector Interface
