BlueOptics SFPFX-09-BO koper-SFP-transceiver, 1250 Mbit/s, RJ-45

The BlueOptics SFPFX-09-BO is a copper SFP transceiver module designed for single-port network links with an RJ-45 interface. It supports data transfer rates up to 1250 Mbit/s, operates from a 3.3 V input and comes in a compact metal housing that weighs approximately 3 g. The module is intended for use in SFP-compatible slots on switches, routers and other networking equipment that accept standard MSA-compliant copper SFP transceivers.

Advantages

This transceiver provides a standardized RJ-45 interface for easy integration into existing copper infrastructure while maintaining a small, robust metal enclosure for mechanical durability and thermal stability. Support for up to 1250 Mbit/s allows it to handle Gigabit and related network protocols. Its low weight and compact SFP form factor make it suitable for dense installations where space and port density matter.

How to use

Insert the BlueOptics SFPFX-09-BO transceiver into a compatible SFP slot on your network device until it latches securely. Connect a standard RJ-45 Ethernet cable to the module’s RJ-45 port and to the corresponding network endpoint. Ensure the host device supports copper SFP modules and the expected data rate. After insertion, verify link status and negotiate speed with the network device; monitor the connection through the host system’s interface to confirm successful operation.

Recommendations

Use in devices that explicitly support copper SFP modules and the required 1.25 Gbit/s class. For reliable operation, keep cable runs within standard copper Ethernet distance limits and use quality Category-rated RJ-45 cables. Avoid exposing the metal housing to prolonged moisture or corrosive environments and ensure the transceiver is handled using ESD-safe practices during installation.
