Description
The Finisar FWLF-1631-25 is an SFP (Small Form-factor Pluggable) transceiver module engineered for high-speed optical communication at 2.7Gb/s. It is designed for extended reach applications, supporting transmission distances of up to 80 kilometers over single-mode fiber (SMF). This makes it an excellent choice for long-haul network links, metro area networks (MANs), and backbone infrastructure where reliable signal integrity over significant distances is essential. The transceiver operates at a specific wavelength of 1557.36nm, which is often utilized in DWDM (Dense Wavelength Division Multiplexing) systems, allowing for high channel density. It features a standard duplex LC connector, providing a secure and robust physical interface for single-mode fiber connections. The SFP form factor ensures compatibility with a wide array of networking equipment, including switches, routers, and optical transport systems. Finisar's expertise in optical components ensures that the FWLF-1631-25 delivers reliable performance and high quality. This transceiver is a key component for building scalable and high-capacity optical networks, supporting the growing demand for bandwidth. Its 80km reach capability combined with its data rate makes it a versatile solution for various telecommunications and enterprise networking scenarios.
