Copper Transceiver Module BlueOptics SFP-1G-RJ45-VA-BO 1250 Mbit/s RJ-45 Silver

The BlueOptics Copper Transceiver Module SFP-1G-RJ45-VA-BO is a compact copper SFP transceiver for 1000BASE-T applications. It provides an RJ-45 interface and supports data transfer rates up to 1250 Mbit/s while operating from a 3.3 V supply. Housed in a lightweight metal casing and weighing approximately 3 g, the module is intended for use in standard SFP slots of switches, routers and other networking equipment that accept compatible 1000BASE-T SFP modules.

Advantages

This SFP module follows MSA-compatible 1000BASE-T mechanical and electrical specifications and is designed to deliver reliable gigabit copper connectivity via an RJ-45 port. The metal enclosure provides mechanical durability and electromagnetic shielding. Compact SFP form factor and low weight make installation simple and allow for high port density in rack-mounted and campus network equipment. The module supports common Ethernet and related protocols at up to 1.25 Gbit/s and is compatible with hardware platforms that accept the corresponding Viavi-compatible SFP modules.

Suitable for

• Gigabit copper uplinks between switches and routers over twisted-pair cabling (Cat5e/Cat6)
• Replacing or expanding RJ-45 SFP ports in network switches and storage systems
• Edge and access layer connections in enterprise and campus networks
• Environments requiring compact SFP modules to maximize port density

Key specifications

• Interface type: RJ-45 copper
• Maximum data transfer rate: 1250 Mbit/s (1.25 Gbit/s)
• Operating voltage: 3.3 V
• Form factor: SFP (small form-factor pluggable)
• Housing: metal enclosure for durability and EMI shielding
• Weight: approximately 0.003 kg

How to use

Insert the SFP-1G-RJ45-VA-BO transceiver into an available SFP slot until it clicks into place and tighten any retention mechanisms as required by the host device. Connect a compatible RJ-45 twisted-pair cable to the module and the remote device. Ensure the host equipment is powered and configured to recognize an MSA-compatible 1000BASE-T SFP; if necessary, enable the corresponding port and configure link speed and duplex settings via the device management interface. Verify link LEDs or system diagnostics to confirm an active connection.

Recommendations

Use Cat5e or better twisted-pair cabling for reliable gigabit operation and keep cable runs within standard specified distances (up to 100 m for 1000BASE-T). Confirm that the host hardware supports third-party or Viavi-compatible SFP modules and, if available, enable Digital Diagnostics Monitoring (DDM/DOM) in host firmware to monitor voltage, temperature and optical/electrical parameters. Avoid exposure to excessive mechanical stress or moisture and install the module in a powered-off or hot-pluggable supported environment according to the equipment manual.
