Product Description
This transceiver module supports data rates up to 2.67Gbps and is built for single-mode fiber optic systems. It uses a 1550nm wavelength with coarse wavelength division multiplexing (CWDM) to transmit signals over distances reaching 50 kilometers. Often found in telecom and enterprise networks, this module fits into SFP slots for flexible deployment. Network engineers and system integrators rely on it for linking switches, routers, and other infrastructure across extended distances without signal loss. Key Features Operates at 2.67Gbps for efficient data transfer Supports single-mode fiber to cover distances up to 50km Uses 1550nm CWDM to reduce channel interference Compact SFP design enables hot-swappable installation Compatible with a range of networking equipment for easy upgrades This transceiver module is typically deployed in metropolitan area networks and long-haul fiber optic links. It helps maintain stable and high-quality connections in scenarios where signal integrity over distance is critical. By integrating this module, network setups can extend reach without requiring additional signal boosting equipment.

Use Cases
The FWLF1621P2T55 Finisar SFP transceiver is primarily utilized in telecom and enterprise networks where long-distance, high-speed data transmission is required over single-mode fiber. It is well-suited for IT professionals managing backbone connections or point-to-point links in environments demanding reliable 50km reach. How It's Used: Connecting data center aggregation switches across campus environments for improved network segmentation and traffic management. Linking remote branch offices to central corporate networks where fiber infrastructure spans extended distances. Supporting metro Ethernet deployments requiring reliable CWDM channels to optimize fiber utilization. Enabling storage area network (SAN) extensions between geographically separated facilities for disaster recovery setups. Integrating into telecom provider networks for backbone connections that require scalable and efficient optical transport. This transceiver facilitates operational efficiency by allowing network architects to extend fiber links without additional amplifiers or repeaters, supporting scalable infrastructure growth while maintaining consistent data rates in critical communication pathways.
