SFP-transceivermodule koper BlueOptics SFP-1G-RJ45-QL-BO 1250 Mbit/s RJ-45

The BlueOptics SFP-1G-RJ45-QL-BO is a copper SFP transceiver module designed for 1000BASE-T Ethernet links. It provides a single RJ‑45 port and supports a maximum data transfer rate of 1250 Mbit/s while operating at a supply voltage of 3.3 V. Housed in a compact metal casing and weighing only 3 g, the module is intended for straightforward installation in SFP-compatible network equipment and is suitable for short-range copper connections up to typical Gigabit-T distances.

Advantages

The transceiver offers a standardized RJ‑45 interface that follows SFP form-factor conventions, enabling broad compatibility with SFP-capable switches, routers and network appliances that accept 1000BASE-T SFP modules. Its metal housing provides mechanical durability and EMI shielding, and the lightweight, compact design simplifies handling and installation. The module supports rates up to 1250 Mbit/s, making it suitable for Gigabit Ethernet environments where a copper RJ‑45 connection is required.

Suitable for

• Connecting SFP-capable switches and routers to copper Ethernet networks
• Replacing or adding Gigabit RJ‑45 SFP ports in data center and enterprise equipment
• Short-range copper links within wiring closets, server racks and distribution frames

Key specifications

• Interface type: RJ‑45
• Maximum data transfer rate: 1250 Mbit/s
• Supply voltage: 3.3 V
• Housing: metal casing
• Weight: 0.003 kg
• Color: silver

How to use

Install the SFP transceiver into an empty SFP slot on compatible network equipment while the device is powered down or hot‑swap according to the equipment manufacturer’s instructions. Insert a standard RJ‑45 copper cable into the module’s RJ‑45 port to establish a connection to the local copper Ethernet network. Verify link status and speed on the host device and ensure the equipment supports 1000BASE‑T SFP modules for full functionality.

Recommendations

Use Category 5e or better shielded/unshielded twisted-pair cables for reliable Gigabit connections and minimize electromagnetic interference by routing cables away from high-power sources. Confirm compatibility with the specific switch or router model and enable any required firmware/driver support for third-party SFP modules when applicable.
