By creating the world's first award-winning, patent-pending optical fibre video patching system, Winchester enables rapid implementation of optical fibre into the broadcast community. The Expanded Light DIN Connect Patch cord is similar in function to the traditional BNC to BNC installed copper wiring terminated to the rear of a copper jackfield. This patch cord has an EL-DIN™ connector on one end and an industry standard LC, SC, FC, ST, (or an single or multi-mode) fiber connector on the other end. The EL Series™ DIN connector end is attached to the rear of the EL Series™ Video Jack and the 2mm Kevlar reinforced fiber is routed to the termination point at the router, or traditional fiber distribution frame.

The Expanded Light Quick Connect is similar in function to a copper video patch cord. With the EL-QC™ connector on either end of a 5mm bend-insensitive rugged fiber, when inserted into the front of the EL Series™ Video Jack, it will automatically switch the optical signal being routed through the back of the video jack to the front connectors.
