Abtract:

This document describes a connector primarily intended for use in television broadcasting and video equipment, such as camera head to camera control-unit connections. It defines hybrid connectors, which contain a combination of electrical contacts and fiber-optic contacts for single-mode fibers. This document also contains nominal dimensions, which ensure nondestructive mating of the electrical and optical interfaces, and functional operability of the electrical interface. Functional operability of the optical interface is dependent upon fiber preparation and termination and is, therefore, not guaranteed by this document. — In addition, this connector has three following characteristics in structure. (a) Ball-lock mechanism: — If metal residue or small particles of dust contaminate the end face of the fiber, the optical power may decrease, and the risk of a communication error increase. The Ball-lock mechanism used is intended to decrease the occurrence of metal residue created by connecting or disconnecting. (b) Position with Shell-key guide groove and Optical ferrule with regard to Jack connector: — The Shell-key guide groove is located on the outside of the jack connector so that if metal residue is created by the mating process, there is very low probability of it contamination the optical ferrule which is covered by Shell. (As shown in Figure 2) (c) Protective mechanism for waterproof with regard to Plug connector — The Waterproofing plane is located inside the extremities of the outer shell, so that it is protected in the event that the connector is dropped in an unmated condition. (As shown in Figure 1) — The connector described in this document is intended for use primarily with the hybrid fiber optic camera cable described in SMPTE 311M; however, this connector may be used independently to meet other requirements.
