| OT8600 Series 1310nm Laser Transmitter | |
|
|
|
Summary |
|
Since 1999
successfully development, circuit having several
improvement, index having great advance, especially
after using RF pre-distortion and RF digital automatic
control circuit developed by our company, this machine
is very perfect not only in dependability, electric
performance index, but also output power stability and
use life. Equipped several structures and cases for
selection. It is suitable for using at large or
middle-size network. | |
|
Performance Characteristic |
- Adopt word-famous company (AGERE, Fujitsu or
selected by user) advanced DFB laser instrument; max
output optical power reach 30mW.
- Add advanced RF pre-distortion circuit, to use as
proofreading CATV system most important CTB and CSO
index, and to improve C/N index.
- Adopt RF digital automatic control technology. It
can automatically adjust drive level and make C/N,
CTB, CSO index always in best state based on input RF
level, number of channels.
- Adopt high performance Gallium Arsenide RF
amplifier, let index higher.
- Built-in perfect power output automatic control
circuit and laser thermoelectricity refrigeratory
temperature automatic control circuit, insures highest
output index and longest life.
- Built-in microprocessor automatic control circuit
makes DFB laser always in best work state.
- Front panel blue VFD display, shows various main
work status parameters and realizes automatic fault
alarm and network management monitor.

| Test condition:
Test
link path is formed of standard fiber and standard
optical receiver. Under the condition of
prescriptive link loss, laser transmitter
modulation depth of each channel being 3.6%, set
59 PAL-D simulative TV channels signal at
47~550MHz and 33 QAM64 digital modulated signal at
the range of 550-750(862) MHz, output level of
digital modulated signal is lower 6dB than of
simulative signal carrier
wave. | | |
