GLB3500A-2T Terr TV a me Twin LNB Optical Transmitter
Hōʻike huahana
ʻO GWT3500S kahi modulation pololei 1550nm DFB laser transmitter no ka hāʻawi ʻana i ka fiber dense. Loaʻa iā GWT3500S hoʻokahi hua hua fiber a me ʻelua hoʻokomo RF: hoʻokahi no 45~806MHz 80ch analog CATV a i ʻole DVB-C QAM a i ʻole DVB-T a ʻo kekahi no 950~2150MHz Satellite Input. Hiki iā GWT3500S ke hāʻawi i ka TV analog, DVB-C/T TV a me DVB-S/S2 satellite TV ma luna o kekahi ʻōnaehana FTTH. Me ka mana kiʻekiʻe optical amplifier, GWT3500S hiki iā FTTH MSO ke hāʻawi ana i ka analog TV, DTT a i ʻole DVB-C, a me ke wikiō ukali ola mai hoʻokahi mea hoʻolele optical.
Hāʻawi ʻo GWT3500S i nā lawelawe TV analog, DVB-C/T/S ma kahi ala maʻalahi. Ma hope o ka nui o nā wikiō kiʻekiʻe e hoʻolaha ana ma 1550nm puka aniani, ʻoi aku ka maikaʻi o nā lawelawe pūnaewele. Hiki iā GWT3500S ke hana me GPON, XGPON, NGPON2 FTTH pūnaewele.
ʻO ka hapa nui o nā RF TV hoʻolaha ma CATV poʻo mai nā modulator wikiō kūloko, koho hou ʻana i ka wikiō satellite a me ka hoʻopuka pūnaewele QAM. ʻO ka ʻoiaʻiʻo, ʻaʻole kūpono ke hoʻololi i nā TV satellite āpau i CATV inā he nui nā ʻike TV kaulana i ka satellite nui. ʻOi aku ka maikaʻi o ka hāʻawi ʻana i ka hōʻailona satellite me CATV RF. Me ka ʻoi aku ka nui o ka ʻōnaehana FTTH i ka GPON no ka lawelawe pūnaewele, hiki ke hoʻonui ʻia ka bandwidth CATV mua RF i 45 ~ 2150MHz, me ka hoʻolaha hoʻolaha kiʻekiʻe kiʻekiʻe CATV a me ka TV Satellite. Ma o ka ʻenehana DWDM, pili ʻo GWT3500S me CATV RF a me ka satellite TV RF i kahi kaʻawale, e hōʻoia ana i ka hana RF maikaʻi loa ma ka hui CATV a me ka hui ukali.
