## Summary description

SFP+ Direct Attach Cable BlueOptics MCP21J1-X002A is a 2 meter passive copper twinax cable compliant with 10GBASE-CR for short-range 10 Gigabit Ethernet links. Designed for SFP+ ports, it enables low-latency, cost‑efficient server-to-switch or switch-to-switch connections in data centers and network racks without additional optical transceivers.

## Long description

The SFP+ Direct Attach Cable BlueOptics 10GBASE-CR 2 m is a passive copper twinax cable designed for short-range 10 Gigabit Ethernet links. Intended for use with SFP+ ports, the cable provides a low-latency, direct server-to-switch or switch-to-switch connection within racks and data center topologies. Its fixed 2 m length and SFP+ connectors make it a plug-and-play alternative to separate optical transceivers and patch cords for short-distance links.
Advantages
This direct attach cable supports the 10GBASE-CR standard over a passive twinax copper assembly, offering reduced hardware complexity and lower per-link cost compared with optical transceiver plus fiber. The fixed copper connection delivers predictable latency and power savings because no active optics or additional transceivers are required. The SFP+ form-factor connectors provide broad compatibility with SFP+ ports on switches, servers and network adapters that support passive copper DACs.
Suitable for
Short-distance 10 Gigabit Ethernet links inside racks and between adjacent racks
Server-to-top-of-rack switch uplinks where low latency and cost efficiency are priorities
Switch-to-switch stacking and cross-connects in data center aggregation layers
Environments that accept passive twinax copper rather than optical fiber for short runs
Key specifications
Interface: SFP+ to SFP+
Data rate: 10 Gbit/s
Standard compliance: 10GBASE-CR
Medium: passive twinax copper cable
Length: 2 meters
Connector form factor: SFP+ (copper DAC)
Typical use range: short-reach, within-rack or adjacent-rack connections
How to use
Insert each SFP+ connector into the corresponding SFP+ port on the two devices to be connected until the latch engages. Ensure both devices support passive SFP+ direct attach copper cables and configure link settings on the switches or servers as needed for a 10 Gbit/s connection. No separate transceivers or fiber patch cables are required; cable is ready for immediate use once both ends are seated and the devices negotiate the link.
Usage recommendations
Verify compatibility with your hardware vendor’s list of supported passive SFP+ DACs before deployment, and avoid sharp bends or kinks in the twinax cable to maintain signal integrity. Use this cable for short, direct connections where heat, power consumption and per-port cost are considerations; for longer links or link diversity, select appropriate optical transceivers and fiber.
