AT5026 DMOD Transmitter
Solutions Provider for FTTx, RFoG and HFC www. ascentcomtec.com
Optical Transmitter adopts high-linearity butterfly DFB laser which is directly modulated to
transmit 47 MHz to 862 MHz and 960 MHz to 2600 MHz signal in a single fiber
Optical Transmitter can choose ITU standard wavelength for DWDM system to extend and
update the networks. It can be amplified by EDFA and EYDFA for huge FTTH system. It can be
Compatible with any FTTX PON technology to realize the combination of CATV, DVB-S ,
Internet and FTTH.
Optical Transmitter adopts 19” standard rack, the parameters of the machine is controlled by
micro-processor, and the status and fault alarm are displayed by the LCD in the front panel.
Standard RJ 45 supports SNMP management. The built-in laser APC, ATC control circuit
assures the long life of the laser and reliable work.
SAT-IF adopts high-linearity IF driving circuit with AGC to ensure the high quality transmission
of Analog TV, Digital TV (DBS-C, DBS-T and Satellite TV in a single fiber
1. Adopt low noise imported DFB laser.
2. Superior pre-distortion circuit design, in achieving high standards of CNR value, there are still
perfect CTB and CSO performance value.
3. Intelligent fan, it began to run when the chassis temperature reaches the set 32 °C to 35 °C.
4. AGC control, so that different RF input level can still maintain a considerable output performance.
5. VFD or LED display, with laser monitoring, digital display, fault alarm, network management and
other functions; once the laser operating parameters deviate from the software set the allowable
range, will alert.
6. With standard RS232 interface for local network management and monitoring of computers.
7. With standard RJ45 interface support SNMP for remote monitoring.
8. High-quality switching power supply, can be 90 VAC to 265VAC or -48 VDC work.
9. Single input with frequency 47 MHz to 2600 MHz.
10. CATV and SAT-IF signal can be transmitted in a single fiber
11. It can be amplified by EDFA and EYDFA, compatible with any FTTX PON technology
