GWT3500S CATV + SAT 1550nm Ikwirakwiza ryiza
Ibisobanuro ku bicuruzwa
GWT3500S ni modulation itaziguye 1550nm DFB ya laser yohereza fibre yuzuye. GWT3500S ifite fibre imwe isohoka hamwe ninjiza ebyiri za RF: imwe kuri 45 ~ 806MHz 80ch igereranya CATV cyangwa DVB-C QAM cyangwa DVB-T naho ubundi kuri 950 ~ 2150MHz. GWT3500S irashobora gutanga TV igereranya, TV ya DVB-C / T na TV ya satelite ya DVB-S / S2 kuri sisitemu iyo ari yo yose ya FTTH. Hamwe na power power optique amplifier, GWT3500S ituma FTTH MSO itanga TV igereranya, DTT cyangwa DVB-C, hamwe na videwo ya satelite yoherejwe na transmitter imwe gusa.
Byinshi byamamaza TV RF kumutwe wa CATV bituruka kubayobora amashusho yaho, amashusho ya satelite yatoranijwe re-modulation hamwe nibisohoka kuri interineti QAM. Mubyukuri, ntabwo ari ubukungu guhindura TV zose za satelite kuri CATV niba icyogajuru nyamukuru gifite ibintu byinshi bizwi kuri TV. Nibyiza cyane gukwirakwiza ibimenyetso bya satelite hamwe na CATV RF. Hamwe na sisitemu nyinshi ya FTTH yohereza GPON muri serivisi ya interineti, umurongo wa CATV utera imbere wa RF urashobora kwaguka kuri 45 ~ 2150MHz, harimo na CATV na TV ya Satelite. Hifashishijwe ikoranabuhanga rya DWDM, GWT3500S ikorana na CATV RF hamwe na TV ya satelite ya RF ukwayo, bigatuma imikorere ya RF ikora neza mugice cya CATV hamwe nitsinda rya satelite.
GWT3500S itanga TV igereranya, serivisi za DVB-C / T / S muburyo bworoshye. Nyuma yubwinshi bwa videwo yo mu rwego rwo hejuru isakara kuri 1550nm idirishya rya optique, serivisi za interineti zifite umurongo mugari. GWT3500S irashobora gukorana na sisitemu ya GPON, XGPON, NGPON2 FTTH.
Ibindi biranga:
•Urusaku ruke cyane umurongo wa DFB laser.
•Kwigenga CATV RF yinjiza na Satelite RF yinjiza.
•Shyigikira transponders zigera kuri 32 kuri satelite 950 ~ 2150MHz RF.
•Inkunga igera kuri 80ch NTSC igereranya TV cyangwa QAM kuri 45 ~ 806MHz RF.
•Imbere yimbere VFD yerekana imiterere yimiterere nubutumwa bwimikorere.
