CRT103 triple channel video transmitter
CAUTION:
THESE OPTICAL UNITS USES CLASS 1M LASER DIODE.
DO NOT STARE INTO BEAM OR VIEW DIRECTLY WITH OPTICAL
INSTRUMENTS. APPLICABLE STANDARD
IEC60825-1: 2001
General
The
CRT103
is a three channel optical transmitter for uni-directional
video transmission in a multimode fibre. The current consumption is
300 mA (+12 VDC).
Frame installation
The
CRT103
module is to be pushed along the guide rails into
the installation frame (e.g.
CSR216
or
316
series) and secured with
the two locking screws. The unit can be freely positioned in any slot in
the frame. The empty positions in the frame should be blanked off with
cover plates. The supply voltage is to be provided by a
CPS384
or
CPS390
power supply unit which are installed back of frame.
Video connections
The impedance of the video inputs (BNC female) is 75 Ω. The nominal
input level is 1 Vpp.
Link status indicator LEDs
In the (uni-directional) CRT103 units the LINK STATUS led is only
monitored by the optical receiver CRR101/103. Therefore the LINK
STATUS led in CRT103 units has no real value and is always green.
