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

The BlueOptics SFP-1G-RJ45-EE-BO is a copper SFP transceiver module designed for 1000BASE-T networks and supports data transfer rates up to 1250 Mbit/s over an RJ-45 interface. Housed in a durable silver metal casing, the module operates at 3.3 V and weighs approximately 3 g. It follows MSA form-factor conventions and is intended for use in compatible switch, router and storage hardware that accepts SFP copper modules.

Advantages

The module provides a compact, hot-pluggable RJ-45 copper interface for Gigabit Ethernet connections, enabling straightforward integration into SFP ports without additional media converters. Its metal housing offers mechanical durability and electromagnetic shielding, while the low weight and standard SFP form factor keep rack and chassis planning simple. Designed and tested for compatibility with common hardware platforms, the transceiver supports standard Ethernet and related high-speed protocols for links up to 100 meters over twisted-pair cabling.

Suitable for

• Connecting Gigabit Ethernet switches and routers via copper (RJ-45) SFP ports
• Server and storage uplinks where SFP copper modules are required
• Short-run campus and data center links over Cat5e/Cat6 copper cabling (up to 100 m)
• Replacement or upgrade of SFP 1000BASE-T copper transceivers in compatible hardware

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 (hot-pluggable)
• Housing material and colour: metal, silver
• Approximate weight: 0.003 kg
• Maximum link distance over twisted-pair cabling: up to 100 m (depending on cable category and network conditions)

How to use

Insert the BlueOptics SFP-1G-RJ45-EE-BO into a compatible SFP slot on the network device while the device is powered according to the vendor's instructions. Connect a standard RJ-45 Ethernet cable (Cat5e/Cat6 or better) between the transceiver and the remote port. Ensure the host device firmware or operating system supports third-party SFP modules and confirm port settings (speed/duplex) if required. For safe hot-plugging, follow the equipment manufacturer's recommendations to avoid link flapping during insertion or removal.

Recommendations

Use high-quality shielded or unshielded twisted-pair cables appropriate for Gigabit Ethernet (Cat5e or Cat6) and keep link lengths within 100 m to maintain signal integrity. Verify host compatibility and enable any required settings for third-party SFP modules in the device management interface. For monitoring and diagnostics, enable DDM/DOM support in the host if available to view real-time operating parameters.
