Fiber optic SFP module CBO SFP-1G-ZX-120KM-NG-BO 1.25 Gbps, single-mode, LC, up to 120 km

CBO SFP-1G-ZX-120KM-NG-BO is a single-mode fiber optic SFP transceiver supporting 1.25 Gbps data rate with LC duplex connectivity and a transmission reach of up to 120 km. The module is designed for telecom and carrier-class environments where stable long-distance links are required between switches, routers and optical transport equipment. Its hot-pluggable SFP form factor enables rapid installation or replacement without powering down equipment.

Advantages

The transceiver provides long-distance optical connectivity over single-mode fiber with low power consumption and stable performance. The LC connector interface offers wide compatibility with standard fiber patch cords and optical equipment. Hot-pluggability and a compact SFP footprint simplify upgrades and maintenance in rack-mounted and field-deployed systems. The module is suitable for point-to-point links and ring topologies in metropolitan and long-haul networks.

Suitable for

• Long-distance 1G Ethernet links between switches and routers
• Fiber backbone connections in carrier and telecom networks
• Optical transport between data centers or telecommunication sites
• Replacement or upgrade of existing single-mode LC SFP ports

Key specifications

• Data rate: 1.25 Gbps (suitable for 1G Ethernet)
• Fiber type: single-mode (SMF)
• Connector type: LC duplex
• Maximum reach: up to 120 km (depends on fiber quality and link budget)
• Form factor: hot-pluggable SFP
• Typical power consumption: low (device optimized for carrier use)

How to use

Ensure that connected equipment supports 1.25 Gbps SFP modules and single-mode LC transceivers. Power down is not required for insertion or removal, but follow your equipment vendor guidelines for hot-swap procedures. Insert the module into an available SFP slot until it clicks, then connect LC patch cords to the transmit and receive ports, observing correct polarity. Verify link status and configure interface settings on the switch or router as needed to enable the optical port.

Recommendations

Use single-mode fiber with appropriate link budget and low-loss connectors for reaches approaching 120 km. Keep LC connectors clean and use protective caps when not in use. Check compatibility lists from your network equipment vendor if vendor lock-in or firmware restrictions are a concern.
