ONS-SI-155-L1

This Cisco single-mode SFP transceiver module is designed to transmit data at 155Mbps over long distances up to 40 kilometers. It operates at a 1310nm wavelength, which is typical for long-reach fiber optic communications. Often found in service provider or enterprise network setups, it enables reliable fiber optic links between switches, routers, or other network devices.

Built for network engineers and IT professionals, this transceiver supports seamless integration with Cisco hardware, making it a practical choice for extending network reach without compromising signal quality. It's commonly deployed in metro, campus, and data center environments where stable long-distance fiber connections are needed.

Key Features

• Supports 155Mbps data transmission rate suitable for legacy and specialized networks
• Operates reliably over 40km distance on single-mode fiber cables
• Utilizes duplex LC connectors for sturdy and easy fiber connections
• Compatible with Cisco devices ensuring straightforward installation and operation
• Operates at 1310nm wavelength optimized for single-mode fiber communication

In practice, this module is often deployed to bridge connections within large-scale campus networks or between data centers where fiber distances exceed typical multi-mode limits. Its ability to maintain consistent signal integrity over 40 kilometers makes it a valuable component in network infrastructures that require steady and long-range fiber links.
