Questions about this item

Will my network need a separate 1000Base-T switch or router to connect the RJ-45 port?

Yes, the single RJ-45 port uses 1000Base-T so it must link to a Gigabit-capable switch or router port with a standard twisted-pair patch cable.

Can I keep my existing 100Base-FX fiber equipment on the same SC duplex link?

No, the SC duplex port is fixed at 1000Base-SX over 850 nm multi-mode fiber, so older 100Base-FX gear will not establish a link.

How do I confirm the converter is passing traffic at Gigabit speed after I connect both cables?

Check that the link LEDs for both the RJ-45 and SC ports are lit solid, then verify the connected switch reports a 1000 Mbps full-duplex connection on that port.
