SFP medený transceiver CBO UF-RJ45-1G-BO 1 Gbit/s 100 m RJ45

CBO UF-RJ45-1G-BO is a 1 Gbit/s SFP copper transceiver with an RJ45 interface designed for up to 100 m over standard Cat5e/Cat6 twisted-pair cabling. The module installs in SFP slots to provide a copper Gigabit Ethernet port where only fiber or modular ports exist, enabling straightforward integration with switches, routers and servers that accept SFP modules. The transceiver supports auto-negotiation of speed and duplex and is intended for short-distance copper links within data centers, wiring closets and office networks.

Advantages

The BlueOptics SFP copper transceiver delivers a compact, hot-pluggable solution for adding 1 Gbit/s RJ45 ports to equipment with SFP interfaces, avoiding the need to replace entire switches. Its compatibility with standard twisted-pair cabling and 100 m reach makes it suitable for common structured-cabling environments. The module reduces cabling complexity by allowing direct copper connections and supports typical Ethernet features such as auto-negotiation and link status reporting.

Suitable for

• Adding Gigabit copper ports to switches or routers with SFP slots
• Connecting servers or access switches within 100 m over Cat5e/Cat6
• Short uplinks between network closets and aggregation switches
• Temporary or permanent network extensions where fiber ports are present but copper connectivity is required

Key specifications

• Interface: RJ45 (8P8C) for twisted-pair copper cabling
• Data rate: 1 Gbit/s (Gigabit Ethernet)
• Maximum reach: up to 100 metres over standard Cat5e/Cat6 cabling
• Form factor: SFP (small form-factor pluggable), hot-pluggable
• Supported features: auto-negotiation of speed and duplex, link/activity reporting
• Operating environment: designed for indoor network installations such as wiring closets and data rooms

How to use

Insert the SFP copper transceiver into a compatible SFP slot on your switch, router or server while the host device is powered on or off, following the device manufacturer's hot-plug guidance. Connect a shielded or unshielded twisted-pair Ethernet cable with RJ45 plugs to the module and the remote device. Confirm link LEDs or the host management interface for link status and speed negotiation. If required, configure the host port settings (speed, duplex, VLANs) via the switch or router management interface.

Recommendations

Use Cat5e or Cat6 cabling in good condition and keep copper runs within 100 m to ensure stable Gigabit performance. Verify SFP compatibility with the host device and consult the equipment documentation if link issues occur. For environments with high electromagnetic interference, prefer shielded cable and proper grounding.
