Description

The Finisar FWLF-1631-58 is a high-performance Small Form-factor Pluggable (SFP) transceiver module engineered for demanding network applications requiring extended reach and reliable data transmission. This module supports a data rate of 2.7 Gigabits per second (Gb/s), making it suitable for various telecommunications and enterprise networking scenarios, including backbone connectivity and metropolitan area networks (MANs). This transceiver operates at a specific wavelength of 1531.12nm, which is optimized for long-distance communication over Single-Mode Fiber (SMF) optic infrastructure. The module is capable of achieving a transmission distance of up to 80 kilometers (km), ensuring robust connectivity between geographically separated network nodes. The use of SMF fiber is critical for maintaining signal integrity and minimizing attenuation over these extensive links. The FWLF-1631-58 features a standard Duplex LC connector, providing a secure and dependable physical interface for fiber optic connections. Its SFP form factor allows for hot-swappable integration into compatible network equipment, such as switches, routers, and optical transport systems, simplifying installation and maintenance processes. This transceiver is a key component for building resilient and scalable network architectures that require long-haul connectivity.
