The optical fiber connectors can be coupled or uncoupled optically when the slidable base advances to and retreat from the base. Further, the slidable base can incline to the base at a position in which the optical fiber connectors are apart each other. Accordingly, in the optical fiber connector adapter in the inclined position can be inserted the other optical fiber connector, then the optical fiber connector adapter can be returned to an original direction and connected with the optical fiber connector mounted on the base for the adapter by being moved near to the base. Therefore both optical fiber connectors are optically coupled via the optical adapter without particular operation to check the position of the first optical fiber connector.

Endoscope with fiber optic transmission of digital video
A video endoscope in which the imaging chip at the distal tip is connected to the proximal connector and operator console by an optical fiber. Video data (preferably digital) is impressed on the optical fiber by a pulse-code modulator (PCM) circuit and light emitter with lensing. A small, inexpensive, flexible optical fiber in the endoscope body conveys the PCM optical data to the receiving circuit, preferably via an optical connector at the proximal end of the endoscope, and to decoding and display circuits in the operator console. The fiber optic transmission overcomes the difficulty of electrical transmission of wide band (digital video) signals via miniature cables, which can be expensive, bulky, inflexible, susceptible to noise and interference, and constitute a potential electrical safety risk by leakage currents. The PCM circuits may be integrated into the camera chip.

Outdoor transceiver connector
ActiveUS20110123157A1Easy to disassembleEasy to useElectric discharge tubesCouplings bases/casesTransceiverElectrical connection
A cable connector assembly for outdoor connection to transceivers. Electrical connection between a component of the cable connector assembly and a connector inside an electronic assembly to which the cable connector assembly is attached is made through a force generated by a biasing member within the cable connector assembly. The biasing member may generate the force as the cable connector assembly is attached to an adapter. Once the cable connector assembly is disengaged from the adapter, the force is released, allowing easy removal of the cable connector assembly, without the need to release a latch. In an environmentally sealed connector in which access to a release mechanism may be restricted, such a structure provides ease of use for either electrical or optical connectors. For optical cable connector assemblies, the optical cable connector may be coupled to a transceiver such that biasing force generated within the cable connector assembly holds the transceiver in a mating relationship with a connector within an electronic assembly but can be easily removed.
