Product Description
This Finisar network transceiver module enables 4.25Gbps communication over single-mode fiber, ideal for long-distance data links. It’s often found in enterprise and service provider networks needing reliable 80km reach without signal degradation. Engineered for DWDM systems, it operates at a specific 1529.55nm wavelength to efficiently handle multiple channels over the same fiber line. Designed especially for network engineers and IT professionals managing fiber optic infrastructure, this module simplifies upgrades and ensures stable performance in metro or long-haul deployments. Key Features Operates on 1000Base-ZX standard for compatibility with Gigabit Ethernet Supports duplex LC connectors for easy fiber cabling Transmits over single-mode fiber for clear, low-loss signal at distances up to 80km DWDM support allows dense channel packing for efficient bandwidth use Wavelength fixed at 1529.55nm to fit within DWDM grid The FWLF1634RL60 is common in telecom networks and data centers where long-range fiber links are necessary. It plays a key role in extending network reach without needing additional repeaters. The precise wavelength control helps network operators maximize fiber utilization in complex optical setups.

Use Cases
The FWLF1634RL60 SFP module is utilized in network infrastructures requiring reliable long-distance fiber optic links, particularly where bandwidth segregation through DWDM is necessary. It is ideal for enterprises and telecom operators managing extended campus networks or inter-building connectivity across metropolitan areas. How It's Used: Connecting data center clusters across distributed enterprise campuses using single-mode fiber for consolidated resource access. Enabling telecom providers to extend 1000Base-ZX Ethernet links between central offices over metropolitan fiber rings. Supporting storage area networks (SANs) that demand low-latency, high-integrity long-haul fiber connections in large-scale virtualization environments. Facilitating remote office interconnections where fiber runs exceed typical short-reach limits, ensuring consistent data throughput. Deploying in rack-mounted network switches within carrier-grade facilities to efficiently manage dense wavelength multiplexed channels. This transceiver contributes to network scalability by supporting high-speed, long-reach links with DWDM compatibility, reducing fiber infrastructure complexity while maintaining signal quality. It aids in sustaining operational efficiency in environments where extended distance and bandwidth management are critical.
