CATV & Satellite Optical Transmitter (ZST9526)
Products Description
ZST9526 Satellite Optical Transmitter adopts high-linearity butterfly DFB laser which is directly modulated to transmit 47-862MHz and 950~2600MHz signal in a single fiber.
It 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.
ZST9526 Satellite 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.
Features
1.Adopt low noise imported DFB laser.
2.Superior pre-distortion circuit design, in achieving high standards of CNR value, there are
3.still perfect CTB and CSO performance value.
4.Intelligent fan, it began to run when the chassis temperature reaches the set 32 ~ 35 ℃.
5.AGC control, so that different RF input level can still maintain a considerable output performance.
6.VFD or LED display, with laser monitoring, digital display, fault alarm, network management
7.and other functions; once the laser operating parameters deviate from the software set the
8.allowable range, will alert.
9.With standard RS232 interface for local network management and monitoring of computers.
10.With standard RJ45 interface support SNMP for remote monitoring.
11.High-quality switching power supply, can be 90V ~ 265V AC or -48V DC work.
12.Single input with frequency 47~2600MHz.
13.CATV and SAT-IF signal can be transmitted in a single fiber
14.It can be amplified by EDFA and EYDFA, compatible with any FTTX PON technology.
