HP Compatible SFP Transceiver

The AddOn J8177C-AO is a hot-swappable SFP transceiver built for HP networking equipment. It delivers a 1000Base-T copper link over a single RJ-45 port. Network administrators use it to extend Gigabit Ethernet connections across existing twisted-pair infrastructure. The module arrives new and initialises identically to the original OEM part.

Gigabit Copper Link for SFP Slots

This transceiver plugs directly into any standard SFP port on a compatible switch or router, requiring no additional cabling beyond a Cat5e or better patch cord. It supports the full 1 Gbps transfer rate across the 100 metre reach. The copper interface frees up fibre patch panels and media converters for simpler rack layouts. MSA compliance allows mixed deployment alongside other vendor modules.

Low Power Operation 0 to 70C

Rated for an operating environment of 0 to 70C, the module runs without active cooling and adds minimal thermal load to the chassis. Power draw is low enough for dense port populations without exceeding the slot budget. Silent operation suits quiet office or campus deployments. The hot-swap design permits replacement without interrupting adjacent links.

Questions about this item

Will the 1000Base-TX copper SFP hit a thermal limit when run continuously at 1 Gbps?

The transceiver is rated for an operating environment of 0 to 70C, so sustained line-rate traffic stays within that range.

How much extra heat and fan noise does the RJ-45 SFP add to a switch under all-day load?

As a passive copper SFP it draws minimal power and adds negligible heat, leaving the switch’s existing cooling unchanged.

What must the host switch provide for this HP-compatible SFP to initialise and pass traffic?

An SFP slot that accepts 1000Base-T modules and follows the MSA pin-out used by the J8177C part number.
