SFP module CBO SFP-1G-ZX-120KM-RW-BO 1.25 Gbps, LC connector, ZX 120 km

The BlueOptics CBO SFP-1G-ZX-120KM-RW-BO is an optical SFP transceiver module that supports a 1.25 Gbps data rate and is intended for long‑reach single‑mode fiber links. The module uses ZX optics to achieve link distances up to 120 km and features an LC duplex connector. It is hot‑pluggable and protocol‑transparent, allowing installation in switches, routers and media converters without requiring device-specific configuration.

Advantages

This SFP module provides reliable long‑distance connectivity with low power consumption and stable optical performance over single‑mode fiber. Its standard LC duplex interface ensures broad compatibility with networking equipment that accepts SFP transceivers. The hot‑plug design simplifies field replacement and upgrades, while protocol transparency supports use across Ethernet and other standard communication protocols.

Suitable for

• Long‑distance backbone links between buildings or sites
• Carrier and metropolitan area networks requiring single‑mode ZX optics
• Connecting switches, routers and media converters over fiber
• Redundant links and disaster‑recovery fiber paths

Key specifications

• Data rate: 1.25 Gbps
• Optical reach: up to 120 km over single‑mode fiber
• Wavelength/optical class: ZX (long‑reach)
• Connector type: LC duplex
• Form factor: SFP (small form‑factor pluggable)
• Hot‑pluggable: yes
• Protocol transparency: supports Ethernet and standard protocols

How to use

Insert the SFP module into a compatible SFP port on a switch, router or media converter until it clicks into place. Connect LC duplex single‑mode fiber patch cables, ensuring correct transmit/receive alignment. After insertion, confirm link status and optical parameters via the host device interface. For removal, depress the module latch and pull the transceiver straight out. Observe ESD precautions and keep protective caps on unused optical ports.

Recommendations

Use the module with single‑mode fiber and LC duplex cables rated for long‑reach applications. Verify device compatibility for third‑party SFP modules with the equipment vendor, monitor optical power and diagnostics after installation, and perform end‑to‑end testing for links approaching the maximum 120 km distance.
