Sony 950, 930, 900 Optical Fiber Overview, Cleaning of the Connector and Cable, Male connector

5 5-1.Optical Fiber Overview

In order to secure the High Definition signal transmission between the HDCU-900/950 to an HDC-

900or HDC-950/930 with a much longer distance compared with the conventional Triax cable, the SMPTE standard optical fiber connector and cable have been adopted. The connecting cable uses two single-mode optical fiber lines, two control lines, and two power lines to carry digitized video, audio, control signals and power to the camera. As a result, an extremely high-quality, all-digital bi-directional video

and audio signal can be transmitted up to a distance of 3 km (1.86 miles)* with the HDCU-900 and 1.2 km (0.75 miles)* with the HDCU-950. To maintain this high performance, an appropriate cleaning is recommended to carry out periodically.

*When supplying power to the camera via the optical fiber cable, the maximum cable length varies with the camera system configuration and lens type, the size of the optical fiber cable and the number of cable connectors.

5-2.Cleaning of the Connector and Cable

• Cotton swabs (commercially available)

Note

Use the cotton swab with a diameter of around 4 mm. The cotton swab with a diameter more than 5 mm does not reach far enough in to the inner part of the cable, to clean the tip of the optical contact.

Female connector

The optical contacts for the female connector are in an unexposed area. When cleaning, it is necessary to - expose the contacts by first removing the alignment sleeve. Proceed as follows.

1.Insert the alignment sleeve remover into the alignment sleeve in a straight line and turn it clockwise.

2.When the turning stops, forcedly pull out the remover in the straight line.

Note

The alignment sleeve can be removed/reinstalled with the sleeve itself attached to the tip of the remover.
