Product identity

The HP Aruba J8177D is a 1G SFP transceiver with an RJ-45 connector for copper networking. It plugs into an SFP slot on a compatible switch or router to add a Gigabit Ethernet port over twisted-pair cable.

Thermals noise power

The module operates within standard SFP power limits and produces no audible noise because it has no moving parts. Heat output is low enough for dense switch chassis without extra airflow requirements.

Build fit

The transceiver accepts Category 5e cable up to 100 metres and fits the standard SFP form factor at 0.5" high, 2.7" wide and 0.6" deep. It adds roughly 0.10 lb and leaves adjacent slots free for other modules.

Questions about this item

How do I install the J8177D into an SFP slot and what step is often missed?

Slide the module in until the latch clicks, then secure the bale clasp; the step often missed is locking the bale clasp after insertion.

What maintenance or replacement will the RJ-45 1000Base-T transceiver need over time?

The transceiver has no moving parts; only the Category 5e patch cord may need replacement if the clip breaks or the cable is damaged.

What limit appears first when the 100m Cat5e link runs at full 1000Base-T speed continuously?

The 100 metre reach defined by the Category 5e standard is the first limit; the link will drop if the cable exceeds that length.
