HPE J9283B – 10 Gb/s SFP+ to SFP+ Passive Twinax DAC Cable (3 m)
Overview
The HPE J9283B is a high-density interconnect accessory designed for short-reach links between SFP+ ports in enterprise switching or server-rack environments. With a 3-metre fixed length and SFP+ connectors on both ends, this passive twinax cable supports up to 10 Gb/s data rate and is intended for use in environments where fibre might be over-kill or where power/latency must be minimal. Real-world deployment situations include linking top-of-rack switches to aggregation switches, server uplinks in adjacent racks, or high-density blade server interconnects. For network engineers, it offers a plug-and-play solution for 10Gig links within racks with minimal infrastructure overhead.
Key Features
-
Supports 10 Gb/s data rate (SFP+ to SFP+) — optimized for short-reach links.
-
Fixed length 3 metres (~9.8 ft) twinax copper cable — suitable for in-rack or adjacent rack interconnects where distance is limite
-
Passive twinax design reduces power consumption and latency compared to active optics or fibre + transceiver combos — useful in dense racks.
-
Recognised by HPE/Aruba switch compatibility documentation as a supported DAC for certain SFP+ ports.
