C-LIGHT 2.5G Multi-rate SFP optical transceivers provide flexible optical connectivity for network systems operating at data rates up to 2.5Gb/s. The product family combines multiple optical reach options within the same SFP platform, making it suitable for network deployments where different fiber distances need to be supported.
The available configurations cover 100m, 2km, 15km, 40km, 80km, 100km, and 120km. Depending on the required transmission distance, the modules use 850nm or 1310nm/1550nm optical wavelengths and are designed for compatible fiber-based network equipment.
The optical module supports data rates up to 2.5Gb/s for compatible Ethernet and synchronous optical networking applications.
The product range includes 100m, 2km, 15km, 40km, 80km, 100km, and 120km configurations for different optical link requirements.
The 100m configuration uses 850nm optics for short-distance fiber connectivity.
1310nm configurations provide 2km, 15km, and 40km transmission options for medium-distance optical networks.
1550nm configurations support 80km, 100km, and 120km transmission over long-distance fiber links.
The standard SFP form factor allows the modules to be integrated into compatible network equipment and high-density optical systems.
The listed configurations use LC connectors for connection to compatible fiber optic infrastructure.
The product specifications include commercial and industrial case-temperature options for different operating environments.
The 2.5G Multi-rate SFP can provide optical connectivity for compatible Ethernet network equipment requiring transmission rates up to 2.5Gb/s.
The modules support optical networking environments based on SONET/SDH technologies and can be selected according to the required fiber reach.
The product family can be deployed in suitable mobile communication infrastructure where optical links are required between network elements.
Enterprise network environments can use the different reach configurations to connect equipment across short or extended fiber paths.
The shorter and medium-distance versions provide optical connectivity options for campus environments with different building and equipment layouts.
The 80km, 100km, and 120km configurations extend the product family to long-distance single-mode fiber applications.
The broad reach range allows network operators to select different optical configurations while maintaining the same 2.5G SFP platform.
From a 100m short-distance option to a 120km extended-reach version, the portfolio covers substantially different network topologies.
The combination of 850nm, 1310nm, and 1550nm configurations allows the optical design to be matched with the required transmission distance.
The product is specified for GE Ethernet and SONET/SDH environments, providing flexibility across different network technologies.
