TIF2000 series CATV& satellite IF externally modulated optical transmitters adopts low-noise & high linearity continuous laser as signal source, and high bandwidth professional LiNbO3 external modulator as external signal modulation. 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 and FTTH.

　　The device is optional for wavelength tunable, with a wavelength adjustment range of ± 0.8nm (± 100GHz) and an interval of 0.4nm (50GHz). The wavelength can be precisely adjusted to meet the needs of different networks.

1.It adopts original top band narrow bandwidth & low-noise laser as signal source, and high linear LiNbO3 external modulator as external signal modulation, it is applied in C ATV & SAT-IF.

2.Single or dual inputs, frequency 47～862MHz & 950~2600MHz.

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

4.Advanced SBS dual band suppression circuit, SBS continuously adjustable, adjustment range: 13~19 for different distance networks.

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

 6. Adopts high linear 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.

7.Different networks can be optimized by OMI adjustment.

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

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

10.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.

11.Standard RJ45 interface provided, supporting remote network management of SNMP and WEB, and remote adjustment of AGC, SBS, OMI and other functions.
