FWLF1634RL49 Finisar 4.25Gbps 1000Base-ZX DWDM 80km Single-mode SFP

This Finisar FWLF1634RL49 transceiver module is designed to provide reliable high-speed data transmission over long distances. It operates at 4.25Gbps using the 1000Base-ZX standard, making it suitable for demanding network environments that require extended reach beyond typical gigabit fiber connections.

Often found in telecom and data center networks, this module supports Dense Wavelength Division Multiplexing (DWDM) technology, allowing for efficient use of fiber infrastructure by multiplexing multiple signals on different wavelengths. Network engineers and infrastructure managers typically select this module when upgrading or expanding fiber optic networks that span up to 80 kilometers.

Key Features

• Operates at a precise 1538.19nm wavelength to fit within DWDM systems
• Supports long-distance transmission up to 80km over single-mode fiber
• Complies with 1000Base-ZX standards for gigabit Ethernet
• Duplex LC connector ensures secure and standard fiber connections
• Compact SFP form factor for easy integration into existing network hardware

This transceiver is commonly deployed in metropolitan area networks and service provider environments where extended reach and channel multiplexing are required. It helps maintain network performance without the need for additional repeaters or amplifiers, simplifying infrastructure while preserving signal quality.
