Copper Transceiver Module BlueOptics X1651-R5-BO 1250 Mbit/s RJ-45

The BlueOptics X1651-R5-BO is a copper SFP transceiver module designed for 1000BASE-T applications. It provides an RJ-45 interface and supports a maximum data transfer rate of 1250 Mbit/s, delivered in a compact silver module that weighs approximately 20 g. The module is RoHS compliant and follows MSA form-factor conventions for SFP copper transceivers, enabling straightforward installation into compatible transceiver slots on switches, routers and other network equipment.

Advantages

The transceiver offers standardized copper connectivity via an RJ-45 port and supports Gigabit-class data rates up to 1250 Mbit/s, making it suitable for typical copper Ethernet links up to the supported cabling distance. Its compact SFP form factor conserves port space in network devices and allows hot-pluggable replacement or upgrades. RoHS compliance indicates conformity with environmental and materials standards. The module’s lightweight metal housing in silver provides mechanical protection and improved thermal behavior compared with bare-board alternatives.

Key specifications

How to use

Install the BlueOptics X1651-R5-BO into an available SFP slot on compatible network equipment until the module latches. Connect a standard RJ-45 twisted-pair Ethernet cable to the module’s RJ-45 port and route the cable to the remote port or patch panel. The device and the host system will negotiate link speed and duplex according to the connected equipment and cabling. If the host system requires specific module configuration or firmware settings, follow the network equipment vendor’s guidelines to enable or verify link parameters and diagnostic features.

Recommendations

Use quality Cat5e or better cabling for Gigabit links and verify that your switching or routing hardware supports third-party SFP copper modules if vendor lock-in policies apply. For reliable operation, avoid mechanical stress on the RJ-45 connector and ensure proper airflow around populated SFP cages to maintain thermal stability.
