SFP transceiver CBO SFP-1G-ZX-120KM-ZY-BO 1.25 Gbps LC single-mode ZX 120 km

CBO SFP-1G-ZX-120KM-ZY-BO is a 1.25 Gbps SFP optical transceiver module designed for single-mode fiber infrastructures. Featuring an LC duplex connector and ZX-class wavelength, the module supports optical links up to 120 km when used with compatible single-mode equipment. The transceiver conforms to standard SFP electrical and mechanical interfaces for straightforward hot-pluggable integration into switches, routers and media converters used in carrier and enterprise networks.

Advantages

The transceiver delivers a stable 1.25 Gbps data rate over long distances while maintaining compatibility with common SFP ports. Its LC single-mode interface and ZX wavelength enable extended-reach links up to 120 km without additional signal conversion. Designed for interoperability, the module eases installation and replacement in existing networks and supports hot-swap operation to minimize service interruptions.

Suitable for

• Long-distance network backbone connections between sites
• ISP and carrier links requiring extended reach
• Telecommunications and metro aggregation rings
• Interconnecting routers, switches and media converters over single-mode fiber

Key specifications

• Data rate: 1.25 Gbps
• Fiber type: single-mode (SMF)
• Connector: LC duplex
• Wavelength class: ZX (long wavelength for extended reach)
• Maximum link distance: up to 120 km (dependent on fiber quality and channel loss)
• Form factor: SFP (hot-pluggable)

How to use

Insert the SFP transceiver into a compatible SFP slot on a switch, router or media converter ensuring the module is fully seated. Connect LC single-mode patch cables to the transmit and receive ports, observing correct polarity. Power on the networking equipment and verify link status through device LEDs or management interfaces. For reliable operation, ensure fiber connectors and patch cords are clean and that the fibre run meets required attenuation limits for the specified distance.

Recommendations

Use this transceiver in matched single-mode environments with appropriate fiber and low-loss connectors. Verify compatibility with the host device and consult link budget calculations for distances approaching 120 km. Regularly inspect and clean LC connectors, avoid bending fiber beyond recommended radii, and monitor link quality via management tools to maintain stable long-distance connections.
