Abstract

The present disclosure describes embodiments of a connector and an optical module, pertaining to the technical field of optoelectronic devices. The connector includes a substrate provided with a through-hole passing through the substrate from a first board surface to a second board surface thereof. The second board surface faces opposite from the first board surface. The first board surface is provided with a first groove and a second groove, and the first groove and the second groove respectively are configured to adapt to different optical fiber splices.

First claim
