Fiber optic SFP module CBO SFP-1G-ZX-160KM-CI-BO 1.25 Gbps LC 160 km

CBO SFP-1G-ZX-160KM-CI-BO is a fiber optic SFP transceiver that supports a 1.25 Gbps data rate over single-mode fiber with an LC duplex connector. The module is specified for link distances up to 160 km, delivering a compact SFP form factor for hot-plug installation in switches, routers and media converters. Designed for long-distance backbone and aggregation links, the transceiver is compatible with standard SFP ports and intended for telecom, ISP and enterprise network environments.

Advantages

The transceiver combines long reach capability with a small, field-proven SFP housing that enables tool-free hot-swap replacement. With an LC duplex interface and single-mode optical design it minimises fibre connector footprint while supporting industry-standard 1.25 Gbps links. The module's optical performance is optimised for extended-distance links, reducing the need for intermediate amplification or repeaters in many deployments.

Suitable for

• Long-distance point-to-point connections between sites and data centres
• Backbone and aggregation links in carrier or ISP networks
• Enterprise WAN links and campus interconnects over single-mode fibre
• Media converters and network equipment with standard SFP ports

Key specifications

• Data rate: 1.25 Gbps
• Optical interface: LC duplex
• Fibre type: single-mode fibre (SMF)
• Typical reach: up to 160 km
• Form factor: SFP (hot-pluggable)
• Transmission wavelength: long-wavelength (ZX class)
• Power and thermal: low-power SFP profile suitable for typical switch and router modules

How to use

Install the module into any compatible SFP slot on a switch, router or media converter while the host is powered on or off according to the device manual. Connect LC duplex single-mode fibre patch cords with correct polarity and ensure end-to-end attenuation and connector cleanliness meet link budget requirements. Configure the host interface for 1 Gbps operation and verify link status through the network device management interface or indicator LEDs.

Recommendations

For reliable operation over long distances, use single-mode fibre with low attenuation and factory-tested LC connectors. Verify link power budget against expected span loss, and inspect or clean connectors before installation. Store spare modules in anti-static packaging and avoid exposure to extreme temperatures or mechanical shock.
