SFP optical transceiver CBO SFP-1G-ZX-120KM-CI-BO 1.25 Gbps 120 km LC ZX

The SFP optical transceiver CBO SFP-1G-ZX-120KM-CI-BO is a single‑mode, hot‑pluggable module designed to provide reliable 1.25 Gbps optical connectivity for long‑reach fiber links. Using an LC connector and ZX wavelength class, this transceiver supports transmission distances up to 120 km, making it suitable for carrier, metro and campus network environments. The compact SFP form factor enables simple field installation in compatible switches, routers and optical equipment.

Advantages

This transceiver delivers long‑reach performance with industry‑standard ZX optics and a single‑mode interface, allowing extended links up to 120 km without repeaters. The hot‑pluggable SFP design simplifies maintenance and upgrades by allowing module replacement without powering down equipment. Its LC connector and standard electrical interface ensure wide compatibility with networking hardware that accepts SFP modules. The module is suitable for stable point‑to‑point fiber connections where low bit‑error rates and predictable latency are required.

Suitable for

• Long‑reach carrier and metro fiber links
• Interbuilding connections on campus networks
• Backhaul links between aggregation switches and routers
• Replacement or upgrade of existing SFP ports for extended reach

Key specifications

• Data rate: 1.25 Gbps (SFP)
• Fiber type: Single‑mode fiber (SMF)
• Maximum link distance: up to 120 km
• Connector type: LC duplex
• Optical class: ZX (long‑reach)
• Form factor: SFP hot‑pluggable module

How to use

Insert the SFP transceiver into a compatible SFP port on your switch, router or optical device while the equipment is powered according to the vendor’s service manual. Terminate the single‑mode fiber with LC connectors and connect the duplex patch cable to the module. Verify link status through the device management interface and check optical power levels and diagnostics if available. To remove the module, follow the equipment manufacturer’s hot‑swap procedure to avoid port or device damage.

Recommendations

Use suitable single‑mode fiber and follow proper fiber handling practices to maintain optical performance. Verify device compatibility with SFP modules and check optical power budgets for links approaching the maximum distance. Store unused modules in anti‑static packaging and avoid contaminating LC connectors prior to connection.
