Copper Transceiver Module BlueOptics R9F87A-BO 1250 Mbit/s RJ-45

The BlueOptics R9F87A-BO copper transceiver module is an SFP-form factor network component that provides a 1250 Mbit/s data link over standard copper cabling. Designed with an RJ-45 interface and a metal housing, this compact module supports typical Ethernet runs up to 100 m while operating from a 3.3 V input. With a lightweight silver chassis and a small footprint, it is intended for integration into switches, routers, media converters and other devices that accept SFP copper modules.

Advantages

The module offers a standard RJ-45 port in an SFP package, enabling flexible port expansion without modifying existing cabling infrastructure. Its metal enclosure ensures mechanical durability and shielding for stable signal performance. Low weight and SFP compatibility make it suitable for space-constrained equipment and easy hot-swap replacement in live networks.

How to use

Insert the transceiver into an available SFP slot on your network device until it clicks into place, then connect a compatible Ethernet cable to the RJ-45 port. Ensure the host device supports copper SFP modules and is powered within the specified input voltage range. After physical installation, verify link status and network configuration on the host device; the module supports standard auto-negotiation and should be recognized as a 1.25 Gbps-capable copper interface where supported.

Recommendations

Install the module in a dust-free environment and avoid excessive mechanical force when handling. Use quality shielded or unshielded twisted-pair cable rated for the intended distance and data rate. For optimal performance, ensure compatible firmware or driver support on the host hardware and follow standard network grounding and cable management practices.
