The SC-DC↑(TM) and SC-QC↑(TM) (SC-DC/SC-QC are registered trademarks of Siecor) are multifiber optical connectors for conventional optical network applications. The SC-DC and SC-QC connectors were designed to provide a new interface technology that is significantly smaller than the duplex SC interface. The small SC-DC and SC-QC connector interfaces occupy half the space of an SC connector, effectively doubling the number of fiber ports in a given space. In addition, SC-DC and SC-QC connectors are simpler to install as well as offering greater packing density for both electronics and cable management. The connector design and performance of the SC-DC/SC-QC connector for both single-mode and multimode applications are described. #1998 society of Photo-Optical Instrumentation Engineers.
