The TE Connectivity 1754371-5 is a duplex clip from the LightCrimp Plus series, designed to hold two LC fiber-optic connectors side by side for a bidirectional link. The beige colour is the standard identifier for multimode LC components, so a field-service tech can visually confirm the fiber type without pulling the connector.
This clip is for use with standard LC connectors — both simplex and duplex types — that are terminated with the LightCrimp Plus crimp tooling. The duplex clip snaps over the two connector bodies and aligns them at the correct center-to-center spacing for LC duplex interfaces.
