Copper SFP Transceiver BlueOptics SFP-9G-BO 1250 Mbit/s RJ-45

The BlueOptics Copper SFP Transceiver SFP-9G-BO is a compact 1000BASE-T module designed for copper Ethernet connections. It provides a single-port RJ-45 interface and supports up to 1250 Mbit/s data transfer while operating from a 3.3 V supply. Housed in a metal enclosure and weighing approximately 3 g, the transceiver follows MSA form-factor standards and is suitable for use in SFP slots of switches, routers and other network devices that support 1000BASE-T SFP modules.

Advantages

This SFP transceiver offers standardized RJ-45 connectivity for easy integration with existing copper infrastructure, a metal housing for mechanical robustness and compatibility with MSA-compliant SFP ports. It supports full-duplex Ethernet at gigabit speeds over twisted-pair cabling and includes support for digital diagnostics (DDM/DOM) when supported by the host hardware. The small, lightweight design reduces space and power impact in dense networking environments.

Key specifications

How to use

Insert the SFP-9G-BO transceiver into an empty SFP port on a compatible device while the host is powered down or following the device manufacturer's hot-swap instructions. Connect a standard Cat5e/Cat6 twisted-pair cable to the RJ-45 port and verify link status through the host device. If the host supports DDM/DOM, monitoring parameters such as supply voltage, temperature and signal levels can be read via the host management interface for diagnostics and maintenance.

Recommendations

Use high-quality shielded or unshielded twisted-pair cabling rated for gigabit Ethernet and limit copper link lengths to recommended distances (typically up to 100 m). Ensure host device firmware supports third-party SFP modules and, if DDM/DOM monitoring is required, confirm the host exposes those diagnostics. Handle the module by its housing and avoid touching the connector contacts; store unused transceivers in protective packaging to prevent contamination or damage.
