Product Description
This Finisar transceiver module operates at 4.25Gbps, ideal for long-distance Ethernet communication using the 1000Base-ZX standard. It's commonly used in fiber optic networks where dense wavelength division multiplexing (DWDM) is required to maximize bandwidth over single-mode fiber. Built for network professionals managing metropolitan or campus networks, it fits into systems needing stable, high-speed connections over extended distances. The module's wavelength of 1550.92nm allows it to coexist with other channels in DWDM setups without interference. Key Features Operates at 4.25Gbps to support Gigabit Ethernet over long distances Uses a 1550.92nm DWDM wavelength for channel multiplexing Supports single-mode fiber transmission up to 80km Equipped with Duplex LC connectors for simple fiber connections Compatible with standard SFP slots for easy integration This transceiver is often installed in telecom or data center environments where extended reach and dense channel spacing are necessary. It provides consistent performance for high-bandwidth links between network nodes separated by large distances.

Use Cases
The FWLF1634RL33 Finisar transceiver is designed for extended distance networking where robust, high-speed connectivity over long single-mode fiber paths is required. It is particularly suited for network environments demanding dense wavelength division multiplexing (DWDM) compatibility and reliable performance across metropolitan or campus-scale fiber infrastructures. How It's Used: Connecting geographically dispersed data centers within a metro area requiring 80km fiber links. Supporting enterprise IT backbone networks that leverage DWDM to maximize fiber capacity in campus environments. Enabling service providers to deliver 1000Base-ZX Ethernet services over long-haul fiber routes. Facilitating high-performance storage area network (SAN) interconnects across distributed racks or buildings. Linking remote office locations to centralized network resources using single-mode fiber with minimal signal degradation. This transceiver ensures consistent data throughput and scalability by integrating DWDM support and extended reach, helping IT infrastructures maintain operational continuity over challenging physical distances and complex fiber topologies.
