HPE X242 10G SFP+ 1m Direct Attach Copper Cable Black

The HPE X242 10G SFP+ 1m Direct Attach Copper Cable (J9281B-C) is a high-performance, passive twinax cable designed for reliable 10 Gigabit Ethernet connections in data centers and enterprise networks. With a length of 1 meter and black jacket, it provides a cost-effective, low-latency solution for short-range interconnects.

Advantages

This cable offers plug-and-play installation with hot-swappable SFP+ connectors, eliminating the need for separate transceivers. Its passive design ensures zero power consumption from the host device, while the 30 AWG copper conductors deliver excellent signal integrity over 1 meter. The robust construction meets SFP+ MSA standards for broad compatibility.
