Network transceiver module TST GTS-SFP-RJ45/1G with SFP socket and RJ-45 Gigabit port

TST GTS-SFP-RJ45/1G is a network transceiver module that provides a Gigabit Ethernet RJ-45 copper interface through a standard SFP slot. The module converts an SFP port into a 1 Gbit/s RJ-45 connection, allowing seamless connection of PCs, switches and other Ethernet devices to SFP-equipped network equipment. It is intended for short-distance copper links and for situations where a flexible port type adaptation is needed without replacing the whole switch.

Advantages

The module offers a compact SFP form factor with a built-in RJ-45 Gigabit port, simplifying upgrades and reducing the need for separate media converters. It supports standard 10/100/1000BASE-T speeds and auto-negotiation for easy integration into mixed networks. Its plug-and-play design requires no additional drivers, and the small footprint preserves valuable SFP slot capacity while enabling copper connectivity where fiber or SFP-only ports are present.

Suitable for

• Converting SFP ports on switches to 1 Gbit/s RJ-45 copper ports
• Connecting standard Ethernet devices to SFP-only equipment
• Short-distance uplinks and access links within server rooms or wiring closets
• Temporary or permanent port adaptation during equipment upgrades

Key specifications

• Interface: SFP socket with integrated RJ-45 8P8C Gigabit port
• Data rate: 1 Gbit/s (supports 10/100/1000BASE-T auto-negotiation)
• Cable type: Category 5e or higher UTP/STP copper cabling recommended for gigabit performance
• Distance: suitable for typical copper link distances (up to 100 meters over appropriate cabling)
• Form factor: hot-pluggable SFP module

How to use

Insert the transceiver into an available SFP slot on compatible network equipment until it seats firmly. Connect an RJ-45 Ethernet cable to the module's Gigabit port and to the remote device. The module supports auto-negotiation and will establish a link at the highest mutually supported speed; verify link/activity LEDs on the host device to confirm operation. Remove the module by pressing the SFP release mechanism on the host and gently pulling the module out.

Usage recommendations

Use Category 5e or better copper cabling and maintain standard wiring practices to achieve reliable 1 Gbit/s performance. Check switch or media converter compatibility lists if available and ensure firmware versions do not restrict third-party SFP modules. Avoid exposing the module to excessive dust, moisture or mechanical stress; handle as a hot-pluggable optical/electronic transceiver and store in anti-static packaging when not installed.
