Detailed Specifications
HP JD495A - 1000BASE-T Copper SFP Transceiver
Overview :
The HP JD495A is a hot-pluggable Small Form-Factor Pluggable (SFP) transceiver module designed for Gigabit Ethernet over copper cabling. It enables IT infrastructure teams to convert SFP ports on switches or routers into RJ-45 copper interfaces, thus leveraging Cat5e or Cat6 cabling for up to 100-metre reach. The unit supports auto-negotiation across 10/100/1000 Mbps speeds and fits into campus access, branch offices or data centres where fibre may not be available or cost-justified. It integrates into standard SFP-port network equipment, allowing engineers to maintain uniform modules and easily replace or upgrade without rewiring.
Key Features :
Supports 10/100/1000 Mbps auto-negotiation speeds
RJ-45 interface for copper cabling up to 100 m reach
Fits SFP form-factor, hot-swappable without system downtime
MSA-compliant SFP, compatible with HP and similar platforms
Operates over standard Cat5e/Cat6 copper infrastructure
