45-860MHz Network 1310nm Optical Transmitter Characteristic: 1.
Dual Module RF drive, high efficiency laser pre-distortion
adjustment 2. Full-automatically Optic Modulation Intensity (OMI)
l, AGC&MGC control. AGC status, input range is 78dBuV~88dBuV,
system index is the best MGC status, input range can be adjusted
75dBuV~90dBuV by the ATT on front panel 3. Front panel has 20 grade
OMI status display(Modulation Depth)., intuitively adjust and
display OMI normal (NOM), low( LOW) or high(HIGH) AGC status, RF is
fixed, OMI is always at NOM status. MGC status, OMI can be at NOM
status by adjusting ATT. 4. Dual power supply inside backup.
Full-automatically switch One is working, the other as cool backup(
suggested) Both are working at the same time, one as hot backup, If
one is damaged, switch to the other full- automatically. Switch
time ≤ 10us. 5. Full- automatically control of casing temperature,
ensure long life of the laser Casing temperature is monitored and
controlled by micro-processor. Display screen shows the actual
operation temperature in time When casing temperature≥ 45, Two fans
at the back panel will open automatically to cool it by constraint
When casing temperature≤ 35, the transmitter will turn down
automatically to ensure longer life of the fans. 6. Dual RF input
port AM interface input 59 routes PAL-D(47-550MHz) Digital
interface(-10dB) input digital video(550-750MHz) 7. Time locked
function Fiber optic transmitter, with time control and lock
function, user can set the working time ( eg, 3 months ) by the
software on the Front panel. If exceeding the fixed time, there
will be alarm, only the password can turn on the machine again
otherwise it will Turn off automatically. Summary: It is important
equipment to set up CATV HFC networks, and primarily used for TV
video signal, digital TV signal, telephone voice Signal and data
(or compressed data) signal long-distance fiber transmission. The
product use import high performance DFB laser Transmitter as light
source, RF drive adopts RF power digital automatic process
technique and advanced RF pre-distortion circuit Developed by our
company and built-in perfect microprocessor automatic monitor
system insure the excellent function of the product. 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. Principle Drawing 5Order Direction *Model
