Abstract

Disclosed are multifiber ferrule assemblies and methods for manufacturing the same. In one embodiment, a finished multifiber ferrule can be provided with a front end having a first front surface that extends beyond a second front surface, thereby inhibiting interaction with a laser beam during processing. A plurality of optical fibers can be fixed within respective optical fiber bores and extend from respective optical fiber bore openings to a position beyond the first front surface. The plurality of optical fibers can be processed by cutting and polishing with a laser beam for providing each optical fiber with a final polished end surface located beyond the first front surface. In further embodiments, an offset structure is positioned with respect to a finished multifiber ferrule after cutting and polishing the optical fibers.
