Koper-transceivermodule BlueOptics R9Q45A-BO 1250 Mbit/s RJ-45

The BlueOptics R9Q45A-BO is a copper SFP transceiver module that provides 1250 Mbit/s data transmission over an RJ-45 interface. Housed in a durable metal enclosure with a silver finish, this compact module is designed for insertion into compatible SFP ports to add copper Ethernet connectivity. It operates at a supply voltage of 3.3 V and has a lightweight form factor of 20 g, suitable for rack-mounted and modular network equipment.

Advantages

The module supports a stable 1250 Mbit/s data rate and uses the widely adopted RJ-45 connector, allowing easy connection to standard copper Ethernet cables. Its metal housing offers mechanical protection and good heat dissipation for reliable operation. The low weight and compact SFP form factor make it easy to install and remove in network switches, routers or media converters without adding significant bulk.

How to use

Ensure the host device supports SFP copper transceivers and is powered off or in a hot-swap-capable state. Align the BlueOptics R9Q45A-BO module with the SFP slot and insert it gently until it clicks into place. Connect a standard RJ-45 Ethernet cable to the module's port and configure the host device for the required link speed and duplex settings if necessary. Monitor link LEDs or device management interfaces to verify successful link negotiation.

Recommendations

Use shielded or unshielded twisted-pair cables appropriate for the desired performance and environment, and avoid exposing the module to extreme temperatures or moisture. For best results, verify compatibility with your switch or router vendor's SFP compatibility list and update device firmware if link issues occur.
