GWT3500S CATV+SAT 1550nm Optical Transmitter
Mafotokozedwe Akatundu
GWT3500S ndi kusintha kwachindunji kwa 1550nm DFB laser transmitter kwa fiber wandiweyani kugawa.GWT3500S ili ndi fiber imodzi yotulutsa ndi zolowetsa ziwiri za RF: imodzi ya 45~806MHz 80ch analogi CATV kapena DVB-C QAM kapena DVB-T ndi ina ya 950 ~ 2150MHz Satellite Input.GWT3500S imatha kutumiza TV ya analogi, DVB-C/T TV ndi DVB-S/S2 TV ya satana pa makina aliwonse a FTTH.GWT3500S, GWT3500S imathandizira FTTH MSO yopereka analogi TV, DTT kapena DVB-C, ndi kanema wa satellite wamoyo kuchokera ku chowulutsira chimodzi chokha.
Ma TV ambiri owulutsa ma TV pamutu wa CATV amachokera ku ma modulator am'deralo, kusinthanso mavidiyo a satana ndi kutulutsa kwa intaneti kwa QAM.M'malo mwake, sizopanda ndalama kutembenuza ma satellite TV onse kukhala CATV ngati satelayiti yayikulu ili ndi zinthu zambiri zodziwika pa TV.Ndikothandiza kwambiri kugawira chizindikiro cha satellite pamodzi ndi CATV RF.Ndi makina ochulukirachulukira a FTTH akutumiza GPON pa ntchito ya intaneti, mayendedwe achikhalidwe a CATV patsogolo RF atha kupitilira mpaka 45 ~ 2150MHz, kuphatikiza kuwulutsa kwapamwamba kwambiri kwa CATV ndi Satellite TV.Pogwiritsa ntchito ukadaulo wa DWDM, GWT3500S imachita ndi CATV RF ndi satellite TV RF padera, kuwonetsetsa kuti RF imagwira bwino ntchito pagulu la CATV ndi gulu la satellite motsatana.
GWT3500S imapereka analogi TV, DVB-C/T/S ntchito m'njira yosavuta.Pambuyo pa makanema ambiri apamwamba kwambiri akuwulutsidwa pawindo la 1550nm Optical, mautumiki apa intaneti amakhala ndi bandwidth yothandiza kwambiri.GWT3500S ikhoza kugwira ntchito ndi GPON, XGPON, NGPON2 FTTH dongosolo.
Zina:
•Phokoso lotsika lalitali kwambiri la DFB laser.
•Kulowetsa kodziyimira pawokha kwa CATV RF ndi kulowetsa kwa Satellite RF.
•Thandizani mpaka ma transponder 32 pa satellite 950 ~ 2150MHz RF.
•Thandizani mpaka 80ch NTSC analogi TV kapena QAM pa 45~806MHz RF.
•VFD yakutsogolo ikuwonetsa magawo ndi uthenga wantchito.
