Glasvezel-SFP-module CBO SFP-1G-ZX-160KM-NG-BO 1,25 Gbit/s LC 160 km singlemode

The CBO SFP-1G-ZX-160KM-NG-BO is a fiber optic SFP transceiver module that supports a 1.25 Gbit/s data rate and uses an LC connector for single-mode fiber links. Engineered for long-distance Ethernet and telecom links, this compact SFP module enables uplinks and network extensions over distances up to 160 km while maintaining compatibility with standard SFP ports in switches and routers.

Advantages

This single-mode SFP module delivers stable 1.25 Gbit/s performance for long-reach connections and fits into the small form-factor pluggable (SFP) slot for easy installation. Its LC connector and single-mode operation reduce signal loss over extended distances. The module is suitable for mixed vendor environments where standard SFP interoperability is required, and its design supports typical enterprise and carrier network topologies without adding significant rack space or power consumption.

Suitable for

• Long-distance Ethernet uplinks between sites and data centers
• Telecom and metro network links requiring single-mode fiber
• Extending backbone connections over fiber spans up to 160 km
• Replacement or upgrade of existing SFP ports on switches and routers

Key specifications

• Data rate: 1.25 Gbit/s (1250 Mbit/s)
• Optical interface: LC duplex connector
• Fiber type: single-mode (SM)
• Maximum reach: 160 km
• Form factor: SFP (Small Form-factor Pluggable)

How to use

Install the module by inserting it into a compatible SFP slot on a switch, router or media converter until it clicks into place. Connect single-mode fiber with LC connectors to the module’s transmit and receive ports, ensuring correct polarity. Configure the network device as required for 1.25 Gbit/s operation and verify link status via the device management interface or LEDs. Follow vendor guidelines for hot-plugging and firmware compatibility when mixing different brands.

Recommendations

To ensure reliable long-distance performance, use ITU-T compliant single-mode fiber and maintain proper fiber routing to avoid sharp bends. Verify optical budget and link loss for spans approaching the 160 km limit, and consider in-line amplifiers or dispersion management if required by network design.
