## Summary description

Direct-attach SFP+ twinax cable CBO 2127931-1-BL, 0.5 m length, with SFP+ male connectors on both ends and 10 Gbit/s data rate. Designed for short-reach high-speed connections between switches, servers and NICs, it provides low latency and reduced power compared with optical transceivers. Ideal for rack-to-rack or intra-rack links in data centers.

## Long description

Direct-attach SFP+ Twinax Cable BlueOptics CBO 2127931-1-BL is a 0.5 m male-to-male copper interconnect supporting 10 Gbit/s data rates for short-reach high-speed links. The cable is designed to connect SFP+ ports on switches, servers and network interface cards (NICs) in data center and enterprise rack environments. As a passive twinax assembly, it offers lower power consumption and reduced latency compared with optical transceivers while providing a cost-effective solution for intra-rack and rack-to-rack connections.
Advantages
The SFP+ Twinax cable delivers a compact and reliable physical link with minimal insertion loss and stable performance over short distances. Its direct-attach design eliminates the need for separate transceivers and LC connectors, simplifying installation and reducing hardware and operational costs. The copper construction provides low latency and predictable signal behavior, and the standardized SFP+ form factor ensures compatibility with compatible networking equipment that supports direct-attach copper connections.
Suitable for
 Intra-rack connections between top-of-rack switches and servers
 Short rack-to-rack links in data center rows
 Direct server-to-switch connections for 10 Gbit/s networks
 High-density patching where space and power efficiency are required
Key specifications
 Form factor: SFP+ male-to-male direct attach cable
 Length: 0.5 m
 Data rate: up to 10 Gbit/s
 Connector type: SFP+ compatible electrical contacts on both ends
 Transmission medium: twinax copper
 Intended reach: short-reach / intra-rack and short rack-to-rack
 Power profile: passive (lower power than optical transceivers)
How to use
Ensure both network devices support SFP+ direct-attach copper cables and are powered down or port-discovered according to the equipment vendor's hot-plug guidance. Align and insert the SFP+ plugs into the corresponding SFP+ cages until the latch engages; verify the link status through the device management interface. For safe removal, follow the host equipment procedure to disengage the latch and pull the cable straight out to avoid damaging the connector or cage. No separate transceivers or fiber patching is required.
Usage recommendations
Use this 0.5 m SFP+ twinax cable for short, fixed connections where 10 Gbit/s performance and low latency are needed. Avoid excessive bending near the connector ends and keep the cable within the recommended operating temperature range of your networking equipment. Verify firmware or compatibility notes from the switch or server manufacturer when deploying in vendor-restricted environments.
