SFP-OC3-LR1= Cisco 155Mbps OC3 Single-Mode 40km 1310nm LC SFP Transceiver

The Cisco SFP-OC3-LR1 is commonly deployed in enterprise and service provider networks requiring reliable long-distance fiber optic connectivity. It is ideal for environments where 155Mbps OC3 transmission is sufficient and robust optical links are needed between dispersed network sites or within metro area networks.

How It's Used:

• Connecting geographically separated data centers within a metropolitan area to maintain high-speed, low-latency links.
• Supporting legacy telecom and enterprise WAN links that operate on OC3 rates for voice and data convergence.
• Extending fiber connectivity to remote office locations in campus or corporate network topologies.
• Interfacing with optical network equipment in service provider access rings requiring single-mode fiber transmission.
• Deployments in storage clusters where dedicated fiber links are used for backup or replication traffic over moderate distances.

This transceiver module facilitates operational efficiency by enabling consistent, long-distance optical connections without complex configuration, supporting scalable network architectures. It is well-suited for networks balancing cost and performance in legacy or specialized OC3 environments.
