Kuparilähetin-vastaanotinmoduuli BlueOptics SFP-1G-RJ45-SP-BO 1250 Mbit/s RJ-45

The BlueOptics Copper Transceiver Module SFP-1G-RJ45-SP-BO is a single‑port copper SFP designed for 1000BASE‑T Ethernet links with a maximum data transfer rate of 1250 Mbit/s. The module uses an RJ‑45 interface in a compact metal housing, operates from a 3.3 V supply and weighs approximately 3 g. It is manufactured to MSA‑compatible mechanical and electrical specifications to provide straightforward insertion into SFP slots on switches, routers and other network devices that support equivalent 1000BASE‑T SFP modules.

Advantages

The transceiver provides full duplex RJ‑45 copper connectivity at gigabit speeds in a standardized SFP form factor, enabling easy hot‑swap replacement and flexible port configuration. Its metal casing offers mechanical robustness and EMI shielding while the low weight and compact dimensions minimize impact on switch port density. The module is built to MSA guidelines to maximise interoperability with equipment that supports standard 1000BASE‑T SFPs.

Suitable for

• Connecting Ethernet devices over copper cabling (Cat5e/Cat6) up to 100 m
• Expanding SFP ports on switches and routers with RJ‑45 copper links
• Use in data center top‑of‑rack switches, aggregation switches and access routers
• Replacement or spare transceiver for network maintenance and upgrades

Key specifications

• Interface type: RJ‑45 copper connector
• Maximum data transfer rate: 1250 Mbit/s (1.25 Gbit/s line rate)
• Supported standard: 1000BASE‑T Ethernet (MSA compatible SFP)
• Power supply: 3.3 V operating voltage
• Housing: metal casing with EMI shielding
• Weight: approximately 0.003 kg
• Product colour: silver
• Maximum copper reach: up to 100 metres over appropriate twisted‑pair cabling

How to use

Install the module into a free SFP slot of a network device while the host device is powered according to the vendor guidance for hot‑swap SFP modules. Connect a compatible RJ‑45 twisted‑pair cable (Cat5e or Cat6 recommended) between the transceiver and the remote Ethernet port. The device should autodetect link speed and negotiate full or half duplex if supported; ensure the switch or router firmware supports generic 1000BASE‑T SFP modules for best compatibility. Monitor link status via the host device management interface and verify physical layer connectivity before introducing production traffic.

Recommendations

Use Cat5e or Cat6 shielded/unshielded twisted‑pair cabling for links up to 100 m, keep firmware and driver compatibility in mind when installing third‑party SFP modules, and follow the host vendor’s guidelines for hot‑swap handling and ESD precautions to ensure reliable operation.
