Medený transceiver modul BlueOptics SFPKT-CU3-BO 1250 Mbit/s RJ-45

The BlueOptics SFPKT-CU3-BO is a copper SFP transceiver module supporting data transfer rates up to 1250 Mbit/s and equipped with an RJ-45 interface. The module is housed in a metal casing, operates from a 3.3 V input, and weighs approximately 3 g. Designed to meet MSA SFP form-factor standards, this compact transceiver provides a standard 1000BASE-T compatible interface for connecting switches, routers and other networking equipment that accept SFP RJ-45 modules.

Advantages

The transceiver offers a compact, industry-standard SFP form factor in a durable metal housing, enabling easy hot-plug installation and reliable electrical connection via an RJ-45 connector. With a rated maximum data transfer rate of 1250 Mbit/s and a low operating voltage of 3.3 V, the module is suitable for Gigabit Ethernet and related applications while remaining energy-efficient and lightweight.

How to use

Insert the SFP module into a compatible SFP slot on the host device until it latches. Connect the RJ-45 port to the copper twisted-pair cable (Cat5e/Cat6 or better recommended for Gigabit performance). Ensure the host device supports SFP RJ-45 transceivers and the intended data rate. Power is supplied through the host slot at 3.3 V; no separate power connection is required. Observe standard ESD precautions when handling the module and avoid excessive mechanical stress on the RJ-45 connector and cable.

Recommendations

Use shielded or properly terminated twisted-pair cabling and maintain appropriate cable lengths (up to the recommended category limits) for reliable 1 Gbit/s operation. Verify compatibility with the host device firmware and, if available, enable or check digital diagnostic features on supported hardware to monitor link parameters and assist with troubleshooting.
