Fibre optic interconnecting devices and passive components - Study of an SC connector adaptor with safety lock mechanism

Scope

IEC TR 63323:2024 deals with a new proposal for an SC adaptor connector which includes a flexible retaining element on its top surface, compared to the SC standard adaptor.
With this solution, when the SC plug connector is in place, any accidental disconnection is difficult, as it employs an external tool or a particular unlocking manoeuvre.
This new adaptor is intended primarily for the home network customer optical fibre termination, but it can be used in every situation where safety issues are important (e.g. main distribution frames in central offices, cross-connect cabinets, street cabinets, termination boxes).
It consists of a push-latch-pull mating sequence connection with the assistance of a suitable tool.
This solution assures compatibility with the existing SC interface standard according to IEC 61754-4.
