Product Description
The Finisar FWLF-1631-20 is a compact, hot-pluggable SFP (Small Form-factor Pluggable) transceiver module designed for Gigabit Ethernet and Fibre Channel applications. It operates at a standard wavelength of 1310nm, making it suitable for medium-reach optical links over single-mode fiber (SMF). This transceiver supports data rates of up to 1.25 Gbps and is specified for distances of up to 20 kilometers. Manufactured by Finisar (now II-VI Incorporated), a leading provider of optical communication components, this module is built to high-quality standards. It typically employs a 1310nm FP laser transmitter and a high-sensitivity PIN photodiode receiver. The FWLF-1631-20 adheres to the SFP Multi-Source Agreement (MSA), ensuring compatibility with a broad range of networking equipment, including switches, routers, and network interface cards that support the SFP form factor. The transceiver features an LC duplex connector, which provides a secure and reliable connection for the fiber optic cable. Its small footprint and ease of installation make it a popular choice for enterprise networks, campus backbones, and service provider deployments where moderate reach and high reliability are required. The FWLF-1631-20 is an effective solution for extending network connectivity over significant distances using single-mode fiber infrastructure.
