Product Description
The Finisar FWLF-1519-7D-35 is a high-performance Small Form-Factor Pluggable (SFP) transceiver module engineered for long-haul optical networking applications. Operating at a data rate of 1.25 Gb/s, this module is specifically designed to transmit data over extended distances on single-mode fiber (SMF) infrastructure. Its impressive 80km reach makes it an ideal choice for connecting geographically dispersed locations or for backbone network links where signal degradation over distance is a primary concern. The transceiver utilizes a duplex LC connector, the industry standard for fiber optic connections, ensuring secure and reliable mating with fiber optic cables. The module's wavelength is specified at 1519nm, which typically falls within the C-band spectrum. This specific wavelength often indicates its suitability for use in Dense Wavelength Division Multiplexing (DWDM) systems, allowing multiple data streams to be transmitted over a single fiber by using different wavelengths. Finisar is a recognized leader in optical communication components, and the FWLF-1519-7D-35 embodies their commitment to quality and performance. This SFP module is designed for compatibility with a wide range of networking equipment, including switches, routers, and network interface cards, providing a versatile solution for extending network reach and capacity. Its robust design ensures reliable operation in demanding enterprise and service provider environments.
