1200480E1 Adtran Compatible 1G SFP SX 550m MMF Transceiver

Decoded, the 1200480E1 is a 1G SX SFP for 550m of multimode fiber over a duplex-LC pair — the Adtran-coded version of exactly that short-reach optic. It is the module you reach for on in-building and campus aggregation links where the run stays inside a couple of hundred metres and multimode is already pulled. The optic seats in a standard SFP cage and links up without a configuration step.
