Statement:
Model: YOT****0nm/YOC****0nm CATV
direct modulation optical transmitter uses DFB laser diode as
optical source，designed with pre-distortion
circuit, can get higher CNR value. Meanwhile, it can guarantee good
CTB and CSO parameter values, and its SBS
value≤*2dB.
Application:
High quality of CATV network
transmission of vide, audio data
Overlay Network
Front-end program broadcast
system
Feature:
Â
- *9″1U Standard
Frame
- LCD
display control in the front panel
- Multiple choices of optical power
output（7—*8dBm）
- Patented pre-distortion circuit
design with higher CNR value
- *5—**0MHz RF
bandwidth
- SBS
adjustable and AGC design
- Built-in microprocessor can provide
excellent control performance
- Equipped with RS—**2 fiber
connector
Instructions:
In the front panel, there is LCD
working condition indicator light andalarm light. When it does not work properly,
alarm light will glitter.Â
1ã€Plug
in the power supply, if it works properly，the
digital panel will say “READY：KEY
OFFâ€ï¼Œand
flash red light.
2ã€To
ensure safe operation of optical transmitter, the power supply has
delaying functions: After boot with key, laser power supply will
not work until after several seconds. Digital panel will display
the machine’s model and Optical output power.
3ã€Operator can use
SELECT（Function）button
to know main working parameters. In the front panel of the LCD
screen, you can seestatus information
according to the
following sequence.
Â
4ã€Any
status information of the machine(refer to the chart above) shows
abnormal，it
will trigger the alarm. Microprocessor will cut off the laser power
supply，and
digital panel will show the cause of the problem.
Â
5ã€When
the LCD screen shows “INTERLOCKâ€ï¼Œand
the red light glitterssimultaneously,
it means the connector of Distal locking joints / alarming relay
connector in the back panel is disconnected. By reconnecting it and
cutting off the power, you can reset
it. Â
Â
6ã€High
RF input electrical level will trigger the alarm(red light
glitters) and you can reset it by cutting off the
power.
