TIF1400 series CATV& satellite IF internally modulated optical transmitters adopts low-noise & high linearity DFB laser as signal source to be directly modulated. It can transmit 47-862mhz CATV signal and 950-2600mhz satellite IF signal on in a single fiber simultaneously.

　　The device is optional for  ITU standard wavelength, which is suitable for DWDM system . It can be amplified by EDFA and EYDFA and compatible with any FTTx PON technology to realize multi networks integration of CATV( Analog & Digital) ,satellite TV (DVB-S) , Internet.

1.RF single input, frequency 47～862MHz & 950~2600MHz.

2.The perfect pre-distortion circuit ensures perfect performance of CTB and CSO in high standard CNR value.

3.Built-in APC and ATC control circuits ensure the long life and high reliable working of the laser.

4.Adopts high linear RF/IF driving amplifying circuit with AGC function to ensure high-quality transmission of analog TV, digital TV (DBS-C,DBS-T) and satellite TV signals in a single fiber.

5.Different networks can be optimized by OMI adjustment.

6.Fully automatic case temperature control, intelligent fans, the fans starts to work when case temperature reaches 30 ℃.

7.Built-in dual  power supply,  hot plug in/out and automatic switching supported.

8.The operating parameters of the whole machine are controlled by  microprocessor, and the LCD status display on the front panel has many functions such as laser status monitoring, parameter display, fault alarm, network management, etc.; once the operating parameters of the laser deviate from the allowed range set by the software, the system will alarm promptly.

9.Standard RJ45 interface provided, supporting remote network management of SNMP and web.
