Transceptor SFP CBO SFP-1G-ZX-120KM-JU-BO 1,25 Gbit/s LC ZX 120 km

CBO SFP-1G-ZX-120KM-JU-BO is a single‑mode SFP transceiver that provides a 1.25 Gbps data link over fiber for long‑reach point‑to‑point connections. With an LC duplex interface and ZX wavelength optics, the module supports transmission distances up to 120 km when used with appropriate single‑mode fiber and compatible equipment. Designed for installation in switches, routers and media converters, the transceiver offers a compact form factor and industry-standard SFP electrical and optical interfaces for straightforward integration into telecom and enterprise network environments.

Advantages

The transceiver delivers stable 1.25 Gbps performance over long distances and uses a standardized SFP form factor for easy hot‑swap installation. Its LC duplex connector and ZX wavelength enable extended reach while maintaining low power consumption and compact size. The module is compatible with common networking devices that accept SFP optics, providing a flexible option for upgrading or extending fiber links without replacing existing hardware.

Suitable for

• Long‑distance point‑to‑point single‑mode fiber links
• Backbone connections between buildings or sites up to 120 km
• Switches, routers and media converters with SFP ports
• Telecom access and enterprise WAN links

Key specifications

• Data rate: 1.25 Gbps (1250 Mbit/s)
• Fiber type: single‑mode
• Connector type: LC duplex
• Wavelength: ZX class (long‑reach optical wavelength)
• Maximum reach: up to 120 km (with appropriate fiber and link conditions)
• Form factor: hot‑pluggable SFP

How to use

Insert the SFP module into a compatible device SFP slot while the host device is powered on or off according to the device manufacturer’s guidance. Connect LC duplex single‑mode fiber cables to the transceiver, ensuring correct transmit/receive orientation. Verify link status and optical power levels through the network device management interface or status LEDs. For reliable operation, use single‑mode fiber with appropriate attenuation characteristics and maintain clean connector endfaces.

Recommendations

Ensure compatibility with the host device firmware and verify optical budget calculations for links approaching the maximum distance. Clean fiber connectors before mating and monitor optical power and BER after installation. Use appropriate ESD precautions when handling the module and store spare units in protective packaging.
