About cable extension length
The maximum allowable cable run when using the
HDFX100 and the HDTX100 depends on the cable type
and the combination of equipment.
Maximum cable run with optical fiber cable
The maximum optical fiber cable length between the
HDTX100 and the HD video camera is 3000 meters
(9840 feet) (when using a portable camera, portable lens,
and 2-inch viewfinder).
Maximum cable run with Triax cable
The maximum Triax cable length between the HDFX100
and the HDC1550 or between the HDFX100 and the
HDTX100 depends on the type of cable, as shown in the
table below.
Maximum cable run between HDFX100 and HD
video camera
The maximum allowable cable run between the HDFX100
and the HD video camera depends on the combination of
equipment, as shown in the table below. The figures in the
table apply to the use of 8.5 dia. Fujikura Triax cable.
1) Additional features on the large lens such as vibration
damping and high-speed servo may result in higher
current consumption (over 2 amperes) which will
reduce the maximum allowable cable run.
Usage Precautions
Installation environment
Make sure that the installation environment fulfills the
following requirements:
• Dry and well ventilated
• Not subject to high temperatures or close to heat sources
• Not subject to strong electric or magnetic fields
• Not exposed to direct sunlight, strong lamps or similar

Before connecting an optical fiber cable to the unit, it is
recommended to clean the optical contacts on the
following parts:
• HDCU connector of HDFX100
• CAMERA connector of HDTX100
• Optical fiber cable
The steps for cleaning are described below.
When an optical connector cleaner (sold
separately) is available
