Product Description
This Finisar transceiver module is designed for long-distance optical communication, transmitting data at 4.25Gbps rates. It’s commonly used in metro and wide-area networks where reliable data transport over extended fiber runs is critical. Built for single-mode fiber systems, the module operates at 1539.77nm wavelength with Dense Wavelength Division Multiplexing (DWDM), allowing multiple data streams on the same fiber without interference. Network engineers and service providers often deploy this type of module to support backbone network connections or inter-building links. Key Features DWDM technology enables dense channel spacing for efficient fiber use High transmission speed suited for gigabit Ethernet and SONET/SDH networks Duplex LC connectors simplify fiber cable management and installation Extended reach aids in connecting distant sites without signal degradation Compatible with a wide range of DWDM equipment for flexible integration This transceiver is typically found in telecommunications infrastructure and enterprise networks where long-haul fiber connectivity is necessary. Its ability to maintain stable signal quality over 80km makes it valuable for linking remote data centers or network nodes.

Use Cases
The FWLF1634RL47 Finisar SFP transceiver is ideal for network infrastructures requiring reliable long-distance fiber optic communication. Its DWDM capability and 80km reach make it well-suited for telecom operators and large enterprise networks that need to extend connectivity between data centers or across campus environments without sacrificing bandwidth or signal integrity. How It's Used: Connecting geographically dispersed data centers in enterprise IT environments for high-speed inter-site communication. Enabling metro area networks (MANs) to aggregate traffic across city-wide fiber backbones. Support for service provider DWDM networks to maximize fiber capacity and deliver multiple channels over a single fiber. Long-haul fiber links in telecommunications infrastructure where duplex LC connections provide straightforward integration. Extending storage area networks (SANs) in campus environments with high bandwidth and low latency requirements. By supporting high data rates over extended distances, this transceiver helps maintain efficient network scalability and performance. Its compatibility with DWDM systems ensures optimal use of fiber resources, catering to evolving demands in complex network topologies.
