SFP transceiver module Copper 1250 Mbit/s RJ-45 BlueOptics SFP-1G-RJ45-QN-BO

The BlueOptics SFP-1G-RJ45-QN-BO is a copper SFP transceiver module with an RJ-45 interface and a maximum data transfer rate of 1250 Mbit/s. Designed for standard SFP slots, this compact silver module weighs approximately 20 g and meets RoHS environmental requirements, providing a straightforward way to add 1G copper Ethernet connectivity to compatible networking equipment.

Advantages

This SFP transceiver supports 1250 Mbit/s throughput over a standard RJ-45 connector, enabling compatibility with many SFP-capable switches, routers and storage devices that accept copper SFP modules. The module's compact form factor allows easy hot-plug installation and replacement, while RoHS compliance and the lightweight metal housing contribute to reliable long-term operation. The BlueOptics module is designed to follow industry MSA behaviour for interoperable use in systems that accept equivalent 1000BASE-T SFP modules.

Suitable for

• Adding 1G copper RJ-45 ports to SFP-capable switches and routers
• Upgrading server and storage interfaces that accept SFP transceivers
• Temporary or permanent links where copper Ethernet is required up to typical 100 m distances
• Environments requiring RoHS-compliant networking components

Key specifications

• Interface type: RJ-45 copper
• Maximum data transfer rate: 1250 Mbit/s
• Form factor: SFP (pluggable transceiver)
• Product colour: Silver
• Weight: 0.02 kg
• Environmental compliance: RoHS

How to use

Insert the BlueOptics SFP-1G-RJ45-QN-BO into a compatible SFP slot on your switch, router or storage appliance while the device is powered according to the vendor's hot-swap guidelines. Connect a standard RJ-45 Ethernet cable to the module's port and verify link/activity LEDs on the host device. Configure interface speed and duplex settings as required by your network equipment; most modern devices will auto-negotiate at 1 Gbit/s. If the host system requires specific firmware or module validation, follow the hardware vendor's instructions for enabling third-party transceivers.

Recommendations

Use high-quality shielded or unshielded twisted-pair cables appropriate for gigabit Ethernet, and keep cable runs within the recommended distance for copper links. Verify that the target device supports third-party SFP transceivers or provides a compatibility mode to ensure reliable operation. For installations in dense racks, ensure adequate ventilation around the SFP ports to maintain nominal operating temperatures.
