Optical Fiber Overview
In order to secure the High Definition signal
transmission between the HDCU-900/950 to an HDC-
900 or 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
transmission between the HDCU-900/950 to an HDC-
900 or 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.
