FWLF1634RL54 Finisar 4.25Gbps 1000Base-ZX DWDM SFP 80km Duplex LC

This Finisar SFP transceiver module enables 4.25Gbps data transfer over single-mode fiber with Dense Wavelength Division Multiplexing (DWDM) support. It's designed for long-distance network links, commonly used in telecommunications and enterprise environments where signals must travel substantial distances without degradation.

Often found in metro networks or data centers, this module fits into switches, routers, or other optical equipment to extend the reach of 1Gbps Ethernet connections beyond typical limits. Network engineers and IT professionals benefit from its reliable performance and compatibility with standard 1000Base-ZX protocols.

Key Features

• Operates at a wavelength of 1534.25nm optimized for DWDM systems
• Supports distances up to 80 kilometers over single-mode fiber
• Complies with 1000Base-ZX Ethernet standards for Gigabit networks
• Equipped with duplex LC connectors for secure fiber connection
• Compact SFP form factor for easy installation into networking hardware

This transceiver is typically deployed in campus backbones, service provider networks, and long-haul fiber links where reliable gigabit connectivity is essential. It helps maintain signal integrity across extended distances, reducing the need for signal repeaters or amplifiers.
