SFP-module CBO SFP-1G-ZX-120KM-LO-BO 1,25 Gbit/s, LC, singlemode, 120 km

The SFP module CBO SFP-1G-ZX-120KM-LO-BO is a single-port small form-factor pluggable transceiver designed for long-distance single-mode fiber links. It operates at a data rate of 1.25 Gbps and uses an LC duplex connector. Intended for network uplinks, metro connections and carrier links, the module supports standard SFP electrical and mechanical interfaces for straightforward hot-plug installation and interoperability with compatible switches and routers.

Advantages

This SFP transceiver provides long reach up to 120 km over single-mode fiber while maintaining a compact SFP form factor. The LC connector type and single-mode optics deliver low attenuation and stable performance for point-to-point links. Compliance with standard SFP interfaces allows hot-swapping without powering down equipment, simplifying maintenance and upgrades. The module is suitable for use in environments where minimal footprint and predictable optical characteristics are required.

Suitable for

• Long-distance uplinks between sites and data centers
• Metro Ethernet and carrier aggregation links
• WAN connections over single-mode fiber
• Network equipment with standard SFP ports (switches, routers, media converters)

Key specifications

• Data rate: 1.25 Gbps
• Fiber type: single-mode
• Connector: LC duplex
• Maximum reach: up to 120 km
• Form factor: SFP (Small Form-factor Pluggable)
• Operating mode: simplex/duplex optical transceiver for point-to-point links

How to use

Install the transceiver into a compatible SFP slot on a switch, router or media converter while the host device is powered on to take advantage of the hot-pluggable design. Connect the LC-terminated single-mode fiber patch cable to the module, observing correct transmit/receive orientation. Verify link status through the host device interface and configure any required network parameters on the connected equipment. For initial deployment, test the optical link budget and monitor signal levels to ensure stable operation over the intended distance.

Recommendations

Use single-mode fiber with appropriate attenuation and dispersion characteristics for long-haul links and follow industry best practices for fiber routing and connector cleanliness. Verify compatibility with the host device manufacturer’s supported transceiver list and ensure firmware or hardware constraints are addressed before large-scale deployment.
