HPE?J9285B ? 10?Gb/s SFP+ to SFP+ Passive Twinax Direct?Attach Cable (7?m)
Overview
The HPE?J9285B is a fixed?length passive twinax (copper) direct?attach cable (DAC) with SFP+ connectors on each end, supporting 10?Gb/s data rates over a 7?metre span. It?s designed for high?density interconnects within racks or between adjacent racks where fibre may be over?spec or where power/latency must be minimal. For a network engineer, this means when you have two SFP+ ports (on switches, servers or stJ9285Borage) within approximately 7?m of each other, you can use the J9285B to link them directly rather than separately buying SFP+ transceivers + patch cables + multimode fibre.
Key Features
-
Supports 10?Gb/s throughput via SFP+ on both ends ? designed for short?reach copper twinax application?
-
Fixed length of 7?metres (~22.97?ft) which gives flexibility for inter?rack or mid?rack connections without extra fibre components.?
-
Plug?and?play SFP+ form?factor, no separate modules required ? simplifies deployment and inventory for high?density racks.
-
Supported in many HPE/Aruba switch models and compatibility guidance exists ? but note: some platforms explicitly do not support the 7?m length version.?
