FIBER OPTIC TRANSMISSION SYSTEMS
Analog Wideband DC-1MHz
Ross Engineering
corporation has developed a HV compact analog fiber optic transmitting and
receiving system, with optional over-voltage limiting designed to drive
instrumentation from a DC to 1MHz signal source. The system is available
with optional multiple input and output ranges of ±0-1V
PK, 0-5V PK to 0-10V PK. It will also operate in conjunction with Ross
Engineering Corporation’s high accuracy high voltage wideband voltage
dividers, which are useful from DC to over 10MHz up to 1,000,000V PK at
0.01% to 3% accuracy. Transmitters and receivers can be powered by either
AC or DC.
Ross HV probes can be
combined with the Ross fiber optic transmission system to provide
isolated, safe instrumentation for accurate high voltage measurement and
transient wave shape viewing and recording. The use of fiber optics
eliminates conductive cable pick-up and ground current effects as well as
isolating high voltage. When a battery or low capacitance isolated power
source is used at the transmitter, the system can isolate the transmitter
from possible power source interference, ground currents, and if necessary
allows it to be at high voltage above ground. The optical and FM mode of
transmission will completely isolate instrumentation and will provide
stable measurement or display in the presence of shock & vibration on
the fiber optic cable and is immune to changes in light intensity.
An optional battery charge
level indicator with low battery shut-off is available to eliminate low
battery error. An optional fiber optic remote controlled on/off switch
which can control the battery operated transmitter from the receiver or
other isolated remote source can save battery power when the transmitter
is in an inaccessible location and is not required to be operative. The
user can also connect an external 12V battery to the external power socket
to allow for longer operating time between battery charge cycles.
Self-aligning fiber optic connectors allow for quick set-up and easy
disassembly for test facility reconfiguration.
Units are available in
single or multiple channel sets. The multiple channel sets are rack
mountable and will accommodate up to four independent and removable
channels. Ross also offers AC/battery operated 50-75 ohm coaxial cable
drivers.
