Fiber optic SFP module CBO SFP-1G-ZX-160KM-IT-BO 1.25 Gbit/s LC for 160 km

Single‑fiber optic SFP transceiver CBO SFP-1G-ZX-160KM-IT-BO supports a 1.25 Gbit/s data rate and uses an LC connector for single-mode links with a specified reach of up to 160 km. The module follows the SFP form factor for hot-pluggable insertion into compatible network equipment, enabling long-distance Ethernet uplinks and fiber backbone connections in telecom and enterprise environments.

Advantages

The module delivers long-reach single-mode transmission in a compact SFP package, allowing network operators to extend links without replacing existing chassis or transceiver cages. Its LC interface and single-fiber design reduce fiber plant complexity while maintaining standard Ethernet data rates. The hot-pluggable SFP form factor simplifies installation and replacement and supports interoperability with equipment that follows standard SFP specifications.

Suitable for

• Long-distance Ethernet uplinks between sites or central offices
• Fiber backbone connections in telecom networks and ISP infrastructure
• Enterprise campus interconnects over single-mode fiber
• Metro and access networks requiring up to 160 km reach

Key specifications

• Data rate: 1.25 Gbit/s
• Transmission distance: up to 160 km over single-mode fiber
• Connector type: LC
• Optical window: long-wavelength (commonly used for extended reach)
• Form factor: SFP (hot-pluggable)
• Single-fiber operation suitable for single-mode links

How to use

Install the SFP module into a compatible SFP slot on network switches, routers or media converters while the host device is powered according to the equipment manual for hot-pluggable modules. Connect the LC fiber patch cable to the module, ensuring correct fiber polarity and cleanliness of connector end faces. After physical connection, verify link status and configure the host interface as required for speed and duplex settings or leave settings on auto-negotiate if supported.

Recommendations

Use single-mode fiber with appropriate attenuation budget and inline amplifiers or dispersion compensation only when required for extended distance. Inspect and clean LC connectors before mating, follow the host equipment vendor compatibility list, and monitor link quality parameters to ensure reliable operation over long-distance links.
