Product Description
This Finisar SFP transceiver module enables 1 Gigabit Ethernet communication over long distances using single-mode fiber. It's commonly used in telecommunications and data center networks where reaching up to 80 kilometers between endpoints is necessary without signal degradation. Network engineers and IT professionals rely on this module to extend their fiber optic network links efficiently. Key Features Operates at 4.25Gbps to handle gigabit network traffic smoothly Designed for 1000Base-ZX standard which supports extended reach optical communication Utilizes DWDM technology at a precise 1531.12nm wavelength to enable multiple channels on a single fiber Equipped with duplex LC connectors for easy and secure fiber connection Single-mode fiber compatibility reduces dispersion for clearer signal over long distances This module is often deployed in metro networks, campus backbones, and other environments where fiber runs exceed typical short-range limits. By integrating DWDM, it allows multiple signals to share the same fiber infrastructure, maximizing capacity without the need for additional cabling.

Use Cases
The FWLF1634RL58 Finisar transceiver is designed for network environments requiring long-distance, high-speed optical connectivity. It suits organizations managing geographically dispersed sites or backbone links where single-mode fiber infrastructure is deployed and precise wavelength management is critical. How It's Used: Connecting data center aggregation switches across campuses up to 80km apart to maintain low-latency, high-throughput links. Enabling enterprise WAN infrastructure for remote offices requiring reliable 1000Base-ZX connectivity over existing fiber backbones. Facilitating DWDM channel expansion in metro networks by leveraging the 1531.12nm wavelength for dense multiplexing. Supporting storage area network (SAN) fabrics that demand long-reach fiber connectivity without signal degradation. Integrating into telecommunications carrier networks for transport of Ethernet services across wide-area fiber routes. This transceiver module helps maintain operational efficiency by providing stable long-range links with precise wavelength specificity. Its compatibility with dense fiber environments supports scalable network growth and tight channel management in complex optical infrastructures.
