FTLF1421S1XCL Finisar OC-3c to OC-48 2.5G 1310nm 10km SFP Transceiver

This Finisar transceiver module provides flexible multirate support from OC-3c/STM-1 through OC-48/STM-16 speeds, making it a versatile choice for various telecom applications. It’s built for single-mode fiber links up to 10 kilometers, operating at the 1310nm wavelength, which is standard for intermediate distance connections.

Often found in telecom and enterprise networks, this module fits into SFP slots on routers and switches designed for SONET data streams. Network engineers and system integrators use it to upgrade or maintain optical links without needing to replace entire devices.

Key Features

• Adaptable to multiple SONET rates, simplifying inventory and deployment
• Supports distances up to 10km on single-mode fiber for metro or campus networks
• Complies with SFP MSA for broad device compatibility
• Operates at a standard 1310nm wavelength suited for diverse networking setups
• Low power consumption helps reduce overall system heat

This transceiver is commonly deployed in telecommunications infrastructure, especially where a range of SONET speeds are in use. It helps maintain reliable, high-speed optical connections in environments that require flexibility without swapping hardware frequently. Its proven design supports smooth network operation in metro, regional, and campus networks.
