1.25 Gbps SM SF 20 km LC BiDi SFP Transceiver 1310/1490 – Compact, Cost-Effective Optical Solution for High-Speed Networking
The 1.25 Gbps Single Mode Single Fiber LC BiDi SFP Transceiver (1310nm/1490nm ) is a high-performance, bidirectional optical module designed to transmit and receive data over a single strand of single-mode fiber (SMF). Operating at a speed of 1.25 Gbps, this SFP (Small Form-factor Pluggable) module provides a cost-effective, space-saving, and power-efficient solution for Gigabit Ethernet and Fiber Channel applications.
By utilizing Wavelength Division Multiplexing (WDM) technology, this module supports full-duplex transmission using two different wavelengths—1310nm for transmission (Tx) and 1490nm for reception (Rx)—over a single fiber. This innovative technology reduces fiber infrastructure requirements by 50% without compromising bandwidth or performance, making it ideal for use in FTTx networks, enterprise backbones, campus environments, and metro Ethernet access.
Key Features
High-Speed Performance
The transceiver supports a data rate of 1.25 Gbps, ensuring fast and reliable performance for Gigabit Ethernet and optical networking applications. It fully complies with the IEEE 802.3z and SFP Multi-Source Agreement (MSA) standards.
