Fiber optic SFP transceiver CBO SFP-1G-ZX-160KM-QN-BO, 1.25 Gbit/s, LC, ZX, 160 km

The CBO SFP-1G-ZX-160KM-QN-BO is a fiber optic SFP transceiver module designed for long-reach single‑mode links. It supports a 1.25 Gbit/s data rate and uses an LC duplex connector with ZX-class wavelength characteristics to deliver reliable optical transmission up to 160 km. The module is intended for installation in switches, routers and optical equipment to extend network connectivity over metropolitan and long-distance fiber infrastructures.

Advantages

This SFP transceiver offers stable single-mode performance for long-distance links with low insertion loss and consistent optical sensitivity. Its compact SFP form factor provides hot-pluggable convenience for field upgrades and repairs without system downtime. The LC duplex interface ensures wide compatibility with standard optical patch cords, and the ZX wavelength provides sufficient reach for extended point-to-point connections.

Suitable for

• Long-distance single-mode fiber connections between sites up to 160 km
• Backbone and metro ring links in service provider networks
• Interconnects between data center switches and optical aggregation equipment
• Upgrading routers and switches to support 1.25 Gbit/s fiber ports

Key specifications

• Form factor: SFP (hot-pluggable)
• Data rate: 1.25 Gbit/s
• Fiber type: single-mode
• Connector type: LC duplex
• Optical class/wavelength: ZX (long wavelength for extended reach)
• Maximum reach: up to 160 km over single-mode fiber

How to use

Insert the SFP module into a compatible SFP slot on a switch, router or optical transceiver chassis while the device is powered on or as recommended by the equipment manufacturer. Connect an LC duplex single-mode patch cable between the module and the remote transceiver or patch panel, observing correct Tx/Rx orientation. Verify link status through the host device interface and monitor optical parameters where supported to confirm proper operation.

Recommendations

Use high-quality single-mode fiber and LC patch cords with appropriate cleanliness standards to maintain low loss. Check equipment compatibility lists for SFP transceiver support and configure the host device for 1.25 Gbit/s operation. Avoid exposing the optical ports to dust; replace protective caps when the module is disconnected.
