Where it fits (and when to choose something else)

Perfect for:

• HPE X120 Series and other SFP-equipped switches

• Horizontal fiber runs in buildings

• Short distances within data centers or wiring closets

• Environments where copper cannot be used

Choose something else if:

• You need longer distance → LX or extended-reach optics

• You need single-mode fiber → SMF optics

• You need 10GbE or higher → SFP+ / QSFP optics

TL;DR

JD118B is HPE’s 1G SX SFP transceiver for multimode fiber:
a short-reach, fiber optic module ideal for uplinks and multimode connections in entry-level and campus networks.
