Modulo in rame SFP CBO BN-CKM-S-T-BO 1250 Mbit/s, 100 m

CBO BN-CKM-S-T-BO is a copper SFP transceiver module designed for 1.25 Gbit/s class links over standard twisted-pair copper cabling. The module supports a data rate of 1250 Mbit/s and a maximum copper reach of up to 100 m, and it fits the compact hot-pluggable SFP form factor for use in switches, routers and media converters. It enables short-distance link connections in data centers, enterprise networks and telecommunications closets where a reliable 1 G-class copper interface is required.

Advantages

The SFP copper module offers a compact hot-pluggable design that simplifies installation and replacement without powering down equipment. Compatibility with standard RJ-45 copper cabling and support for a 1250 Mbit/s data rate make it suitable for gigabit class links over short distances. The module's passive copper interface reduces complexity compared with optical transceivers and delivers cost-effective connectivity for switch uplinks and inter-switch connections.

How to use

Insert the SFP module into an SFP slot on a compatible switch, router or media converter until it latches. Connect the module to the network using standard twisted-pair copper cabling terminated with RJ-45 connectors, making sure cable type and length remain within the specified 100 m maximum. The module is hot-pluggable; ensure firmware or device compatibility if the host requires vendor identification or specific transceiver support. Monitor link LEDs on the host device to confirm carrier presence and negotiated speed.

Recommendations

Use shielded or unshielded twisted-pair cable that meets category specifications for your network design, keep cable runs under 100 m, and avoid excessive bends or electromagnetic interference near power lines or heavy machinery. Verify host device compatibility with copper SFP modules and update device firmware if necessary to ensure proper detection and operation.
