Product Description

GWT3500S is a direct modulation 1550nm DFB laser transmitter for fiber dense distribution.  GWT3500S has one fiber output and two RF inputs: one for 45~806MHz 80ch analog CATV or DVB-C QAM or DVB-T and the other for 950~2150MHz Satellite Input.  GWT3500S can delivery analog TV, DVB-C/T TV and DVB-S/S2 satellite TV over any FTTH system.  Together with high power optical amplifier, GWT3500S enables FTTH MSO offering analog TV, DTT or DVB-C, and live satellite video from just one optical transmitter.

GWT3500S provides analog TV, DVB-C/T/S services at a simplest way. After huge amount of high quality videos are broadcasting at 1550nm optical window, Internet services have more effective bandwidth.  GWT3500S can work with GPON, XGPON, NGPON2 FTTH system.

Most broadcasting TV RFs at CATV headend are from local video modulators, selected satellite video re-modulation and internet QAM output. In fact, it is not economical to convert all satellite TV to CATV if the main satellite has a lot of popular TV contents. It is more efficient to distribute satellite signal along with CATV RF.  With more and more FTTH system deploy GPON for internet service, the traditional CATV forward RF bandwidth can be extended to 45~2150MHz, including rich high quality broadcasting CATV and Satellite TV. By means of DWDM technology, GWT3500S deals with CATV RF and satellite TV RF separately, ensuring best RF performance at CATV band and satellite band respectively.
