Ricetrasmettitore SFP CBO SFP-1G-ZX-120KM-SS-BO 1,25 Gbit/s monomodale LC, 120 km

CBO SFP-1G-ZX-120KM-SS-BO is an SFP optical transceiver module that supports a 1.25 Gbps data rate over single-mode fiber using an LC connector. Engineered for long-reach point-to-point links, the module provides a nominal transmission distance of up to 120 km and fits standard SFP ports. It is intended for integration into network switches, routers and transport equipment where extended fiber reach and single-mode performance are required.

Advantages

The module offers stable 1.25 Gbps performance over single-mode fiber and a compact SFP form factor for hot-pluggable installation. The LC connector and single-mode optics minimize insertion loss on long links, while compatibility with standard SFP interfaces simplifies deployment in existing network hardware. The design emphasizes predictable optical reach and straightforward interoperability with carrier and enterprise equipment that support optics of this class.

Suitable for

• Long-distance Ethernet links between sites and data centers
• Backbone connections in ISP and telecom networks
• Metro and campus fiber links requiring single-mode reach
• Replacement or upgrade of SFP ports to extend link distance

Key specifications

• Data rate: 1.25 Gbps
• Fiber type: single-mode fiber (SMF)
• Connector: LC duplex
• Nominal reach: up to 120 km
• Form factor: SFP (hot-pluggable)
• Optical interface: single-mode long-range (ZX)

How to use

Install the transceiver into an available SFP port on a compatible switch, router or optical transport device while powered on or following the host equipment vendor guidelines for hot-plugging. Connect LC-terminated single-mode fiber cables to the transmit and receive ports with correct polarity. Verify link parameters and diagnostics through the host device management interface and ensure optical budget and attenuation are within acceptable limits for the intended span.

Recommendations

Confirm that both ends of the link use compatible single-mode optics and LC connectors and that fiber attenuation and any inline components (splices, connectors, multiplexers) do not exceed the module's optical budget. Use clean LC connectors and follow electrostatic discharge precautions when handling the transceiver.
