StarTech.com 813874B21ST — HPE Compatible 10GBASE-T SFP+
HPE 813874-B21 coded10GBASE-TRJ-45Up to 30 m
The StarTech.com 813874B21ST is a copper SFP+ module coded to work as the HPE 813874-B21, turning an SFP+ cage into a 10GBASE-T RJ-45 port. It runs at 10 Gbps over Cat6 or Cat5e cable up to 30 m. StarTech.com lists it for HPE SN2010M switches and BladeSystem c-Class interconnects such as Virtual Connect Flex-10/10D and FlexFabric 10Gb/24-port modules. In practice, a copper module is the quickest way to connect a nearby device that only has an RJ-45 port, without buying a media converter. Keep it for short runs next to the switch and use fibre for anything further away.
Compatibility — check before buying:
It runs at 10 Gbps only — StarTech.com does not publish 1G, 2.5G or 5G operation, so a 1G device at the far end may not link. Reach is 30 m, not 100 m. At 2.3 W it draws and heats more than an optical module; some switches limit how many copper SFP+ modules can run side by side. It is coded for HPE 813874-B21; the uncoded version is SFP10GBTST and the Cisco-coded version SFP10GBTCST. Not sure? Send us your switch model and the cable run and we check it before you order.
Best For
✓ 10G copper link to a nearby server or NAS
✓ Using a spare SFP+ cage as an RJ-45 port
✓ Short runs inside a rack or room
✓ Avoiding a separate media converter
✓ Lab and test setups
✓ Replacing a failed copper SFP+ module
Key Features
Coded for HPE 813874-B21
Identifies as the HPE copper module, for HPE interconnects and switches that check module coding.
Copper instead of fibre
Turns an SFP+ cage into a 10GBASE-T RJ-45 port, so a switch can reach a nearby 10G server or NAS over twisted-pair cable. Reach is 30 m, far shorter than the 100 m of standard copper Ethernet.
Hot-swappable
Modules plug into a live port without shutting the switch down, so a link can be added or replaced during working hours. Seat it until it clicks and use the latch to remove it.
Plan both ends together
A link only comes up when both ends use the same standard, speed and media. Order the far-end part, the cabling and any spares in one go and the link works on day one.

Frequently Asked Questions
Singular Expert Insight
Copper SFP+ is handy for a 10G server a few metres from the switch, but it is not a fibre replacement: keep runs under 30 m and mind the 2.3 W per port. For HPE gear that expects 813874-B21 coding, this is the StarTech.com part to order. Every order is backed by Singular’s local support in Cyprus — if a link will not come up, send us the port status from the switch and we help you find out whether it is the optic, the cable or the configuration. Browse all transceivers and DAC cables or the switches they plug into.
Buyer’s Guide
Buy it if
You need a 10G RJ-45 port on HPE gear that expects 813874-B21 coding, with a run under 30 m.
Skip it if
The far end is 1G or multi-gig only, the run is over 30 m, or your switch is Cisco (SFP10GBTCST).
Also consider
