HPE JW089A – 1 Gb RJ-45 SFP Transceiver Module (10/100/1000Base-T)
Overview
The HPE JW089A is a copper-based SFP transceiver module designed for enterprise network access or wiring-closet uplinks where fibre is not required. It supports 10/100/1000Base-T over standard twisted-pair cables (Cat5e/Cat6) and has a reach of up to 100 metres. It plugs into standard SFP slots in HPE/Aruba switches or mobility controllers, providing a cost-effective way to use existing copper infrastructure for gigabit links to access switches or patch panels.
In real-world deployment this module is useful when fibre runs are impractical, or in multi-building campuses where you might have copper runs to a nearby cabinet. It fits in scenarios where you need a straightforward RJ-45 interface in the SFP cage rather than using a traditional RJ-45 port.
Key Features
-
Supports 10/100/1000 Mbps auto-negotiation over standard copper twisted-pair (Cat5e/Cat6) cables, simplifying add-ons in wiring closets.
-
RJ-45 connector within SFP form-factor enables module insertion into SFP port and keeps your port density/flexibility intact.
-
Certified reach up to 100 metres over copper, making it viable for typical closet-to-closet or rack-to-rack links without fibre.
-
Fully hot-swappable in supported HPE/Aruba gear — you can replace or upgrade modules without shutting down the switch or link.
