SFP+ Copper Transceiver StarTech SFP10GBTCST — 10GBASE-T SFP to RJ45 (Cat6/Cat5e), 10 Gbit/s, RJ-45 30 m

The StarTech SFP10GBTCST is a copper SFP+ transceiver that enables 10GBASE-T Ethernet over Cat6/Cat5e cabling using an RJ-45 connector. Designed for SFP+ ports, the module provides 10 Gbit/s connectivity over copper for distances up to 30 m and comes in a zinc steel silver housing with a typical power consumption of approximately 2.3 W and an MTBF of about 4.6 million hours. The module is hot-swappable for simple installation and replacement in compatible switches and routers and is offered with StarTech.com lifetime warranty and multilingual technical support.

Advantages

This SFP+ copper transceiver supports full 10 Gbit/s data rates on existing Cat6/Cat5e copper infrastructure and provides RJ-45 connectivity without requiring fiber cabling. The compact SFP+ form factor lets you add 10GBASE-T copper ports to switches or routers that have SFP+ slots, reducing the need for separate media converters. Metal housing offers mechanical durability, and hot-swappable operation minimizes downtime during upgrades or replacements.

Suitable for

• Upgrading SFP+ ports on switches and routers to 10G copper Ethernet
• Short-reach 10 Gbit/s links over Cat6/Cat5e cabling within data centers or server rooms (up to 30 m)
• Connecting RJ-45 copper devices to equipment with SFP+ interfaces

How to use

Insert the SFP10GBTCST into a compatible SFP+ slot on your switch or router until it clicks into place, then connect an RJ-45 Cat6 or Cat5e cable between the transceiver and the copper Ethernet port on the other device. Ensure connected equipment is configured to recognize 10GBASE-T links and verify link status through the switch/router management interface. The transceiver is hot-swappable, so it can be installed or removed without powering down compatible equipment, but follow your organization's change control procedures to avoid unintended network disruption.

Usage recommendations

Use high-quality Cat6 cable for reliable 10G performance and keep cable runs within the specified 30 m maximum. Verify compatibility with your switch or router model — while the module is Cisco-compatible and designed to work with many vendors, check firmware and hardware compatibility lists if available. Install in environments with adequate ventilation to maintain typical power consumption characteristics and prolong service life.
