Optical SFP module CBO SFP-1G-ZX-120KM-UQ-BO 1.25 Gbps LC single-mode 120 km

BlueOptics CBO SFP-1G-ZX-120KM-UQ-BO is a 1.25 Gbps optical SFP transceiver designed for single-mode fiber links with an LC connector and an extended reach of up to 120 km. The module supports standard SFP hot-pluggable installation and is intended for long-distance gigabit connections in telecom, ISP backbone and enterprise WAN environments. It is engineered to meet common optical interface requirements and provides a compact form factor for integration into switches, routers and media converters that accept SFP modules.

Advantages

The module provides stable 1.25 Gbps data transmission over single-mode fiber and supports long-distance links up to 120 km without intermediate amplification in typical conditions. Its hot-pluggable SFP form factor enables easy replacement and flexible deployment in network equipment that accepts SFP transceivers. The LC duplex connector ensures reliable mating with single-mode fiber patch cables while minimizing space in dense fiber panels.

Suitable for

• Long-distance point-to-point gigabit links in metropolitan and regional networks
• ISP backbone connections and aggregation links
• Enterprise WAN links between sites and data centers
• Integration with switches, routers and media converters that support SFP modules

Key specifications

• Data rate: 1.25 Gbps
• Fiber type: single-mode fiber (SMF)
• Connector type: LC duplex
• Maximum reach: up to 120 km (typical single-mode conditions)
• Form factor: SFP (hot-pluggable)

How to use

Insert the SFP transceiver into an SFP slot on compatible network equipment while the device is powered on or off according to the host device guidelines. Connect the LC duplex single-mode patch cable to the module, observing correct transmit and receive orientation. Verify link status on the host device and configure interface settings such as speed and duplex if required by the equipment. For optimal operation, ensure fiber optics are clean and connectors are free from dust or damage before mating.

Recommendations

Operate the transceiver within the ambient temperature and optical power ranges specified by the host equipment. Use single-mode fiber with appropriate attenuation characteristics for links approaching the maximum distance and consider optical budget margins when planning long runs.
