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

CBO SFP-1G-ZX-120KM-IT-BO is a hot-pluggable SFP transceiver designed for long-distance single-mode fiber links. Supporting a data rate of 1.25 Gbps and using an LC connector with ZX wavelength, this module provides extended reach up to 120 km for telecom and enterprise network environments. It is intended for fiber uplinks, long-haul connections and backbone extensions where stable single-mode performance and compatibility with SFP ports are required.

Advantages

The transceiver offers long-reach transmission over single-mode fiber with a ZX wavelength optimized for distances up to 120 km. Hot-pluggable form factor enables on-the-fly installation and replacement without powering down equipment. With a compact SFP footprint and LC duplex interface, it integrates into standard network switches, routers and optical transport equipment. Industrial temperature range support improves reliability in varied operational environments.

Suitable for

• Long-haul fiber links between sites up to 120 km apart
• Backbone and metro networks requiring single-mode ZX wavelength transmission
• Fiber uplinks between switches, routers and optical aggregation devices
• Telecom and enterprise environments needing hot-pluggable, compact transceivers

Key specifications

• Data rate: 1.25 Gbps
• Optical mode: single-mode fiber (SMF)
• Connector type: LC duplex
• Wavelength: ZX (long wavelength optimized for extended reach)
• Maximum reach: up to 120 km
• Form factor: SFP (hot-pluggable)

How to use

Insert the SFP transceiver into a compatible SFP port on a switch, router or optical device while the device is powered on. Connect LC single-mode fiber cables to the module's duplex LC connector, ensuring correct transmit/receive orientation. Verify link status through the host device's interface and monitor optical levels to confirm proper operation. When replacing or removing the module, follow the equipment manufacturer's hot-swap procedure to prevent signal interruption.

Recommendations

Use high-quality single-mode fiber with appropriate attenuation characteristics for long-distance links and ensure clean LC connectors to maintain signal integrity. Verify compatibility with the host device and enable any required configuration for 1.25 Gbps operation. For runs approaching the maximum 120 km distance, check optical power budget and consider inline amplification or dispersion management if necessary.
