Transceptor de fibra óptica CBO SFP-1G-ZX-120KM, 1,25 Gbit/s, monomodo, 120 km

The Fiber Optic Transceiver CBO SFP-1G-ZX-120KM is a single-mode SFP module that supports a 1.25 Gbps data rate and is designed for long-distance links up to 120 km. Compatible with standard SFP ports, this transceiver provides optical connectivity for telecom infrastructures, internet service providers and enterprise backbone networks that require extended reach and stable signal transmission.

Advantages

The module delivers extended-range single-mode transmission while maintaining low power consumption and a compact SFP form factor. It supports hot-swappable installation into equipment with SFP ports, enabling quick replacement or upgrades without system downtime. Built to meet common optical interface standards, the transceiver ensures interoperability with a wide range of switches, routers and optical equipment used in long-haul network segments.

Suitable for

• Long-distance fiber links between sites up to 120 km apart
• Telecom and ISP backbone connections
• Enterprise campus or data center interconnects requiring single-mode optics
• Network upgrades where standard SFP compatibility is required

Key specifications

• Optical mode: single-mode fiber (SMF)
• Data rate: 1.25 Gbps (SFP 1G)
• Maximum reach: up to 120 km over single-mode fiber
• Form factor: SFP (small form-factor pluggable), hot-swappable
• Wavelength: typical long-range wavelength for ZX class optics
• Connector type: LC duplex optical connector compatible
• Power characteristics: low power consumption suitable for rack and chassis installations

How to use

Insert the transceiver into a compatible SFP slot on a switch, router or optical media converter with the module latch aligned and fully seated. Connect a single-mode duplex LC patch cable between transceivers at each end of the link, observe transmitter/receiver orientation, and verify link status through device LEDs or management interfaces. Ensure both ends use compatible single-mode ZX-class optics and that fiber plant attenuation and transceiver budget support the intended 120 km span.

Recommendations

Prior to deployment, test the fiber link for attenuation and continuity, verify that both endpoints use single-mode LC connectors, and confirm equipment compatibility with 1.25 Gbps SFP modules. For links approaching the maximum reach, consider optical loss budget, use of low-loss connectors and splices, and consult link planning tools to ensure reliable operation.
