SFP transceiver module BlueOptics SFP-1G-RJ45-PS-BO Fiber optic 100 m

The BlueOptics SFP-1G-RJ45-PS-BO is an SFP transceiver module designed for 1 Gbit/s network connections over twisted-pair cabling with an RJ45 interface. Housed in an aluminium casing and weighing approximately 20 g, this compact module supports data transmission up to 100 metres and fits standard SFP ports following MSA (Multi-Source Agreement) mechanical specifications. It is intended for use in network equipment that accepts SFP 1000BASE-T transceivers and requires reliable, plug-and-play copper connectivity in a small form factor.

Advantages

The module offers single-port copper connectivity in an industry-standard SFP form factor, enabling flexible upgrade or replacement of SFP-capable network hardware without the need to change chassis or line cards. Its aluminium housing provides basic mechanical protection while keeping weight low for easy handling and installation. Compatibility with 1000BASE-T protocols and a 100 m link range make it suitable for typical office and data center horizontal cabling runs.

Suitable for

• 1 Gbit/s uplinks and server connections over copper cabling
• Switch-to-switch or switch-to-server links within 100 m
• Environments where SFP slot flexibility is required instead of fixed RJ45 ports
• Network hardware that supports standard SFP 1000BASE-T transceivers

Key specifications

• Form factor: SFP (small form-factor pluggable)
• Data rate: 1 Gbit/s (1000BASE-T)
• Connector: RJ45 (copper, twisted pair)
• Maximum link distance: up to 100 metres over appropriate Cat5e/Cat6 cabling
• Housing material: aluminium
• Weight: approx. 0.02 kg
• Protocol support: Ethernet 1000BASE-T

How to use

Insert the BlueOptics SFP-1G-RJ45-PS-BO into an available SFP port on a compatible switch, router or server while the device is powered on or following the vendor's hot-plug guidelines. After seating the module, connect a suitable RJ45 twisted-pair cable to the transceiver and to the remote network device. The host device should detect the 1000BASE-T link and negotiate speed and duplex automatically according to standard Ethernet autonegotiation. If required, consult the host vendor documentation for any platform-specific transceiver enablement or firmware considerations.

Recommendations

Use quality Cat5e or Cat6 cabling for runs up to 100 metres, avoid sharp bends and sources of electromagnetic interference near the cable route, and verify that the host device firmware and configuration allow third-party SFP modules if vendor lock-in restrictions exist. For environments requiring digital diagnostics, ensure the receiving hardware supports DDM/DOM to access real-time monitoring where available.
