Hobaneng o kenya Satellite holim'a GPON
Direct Broadcasting Satellite (DBS) le Direct to Home (DTH) ke mekhoa e tsebahalang haholo ea ho natefeloa ke TV ea sathelaete lefatšeng ka bophara.Ho e etsa, satellite antenna, coaxial cable, splitter kapa multi-switcher le satellite receiver lia hlokahala.Leha ho le joalo, ho kenya antenna ea sathelaete ho ka ba thata ho ba ngolisitseng ba lulang lifoleteng.SMATV (satellite master antenna TV) ke tharollo e ntle bakeng sa batho ba lulang mohahong kapa sechabeng ho arolelana sejana se le seng sa satellite le antenna ea lefatše.Ka thapo ea faeba, lets'oao la SMATV RF le ka fetisetsoa ho 20Km hole kapa la abeloa lifolete tse 32 ka kotloloho, ho 320 kapa 3200 kapa 32000 foleteng ka GWA3530 fiber optic amplifier.
Na see se bolela hore satellite MSO kapa satellite system integrator e lokela ho kenya thapo ea fiber ea poraefete ho motho e mong le e mong ea ngolisitseng?Ha e le hantle, re hloka fiber ho motho e mong le e mong ea ngolisitseng haeba re khona, empa ha ho hlokahale haeba ho na le fiber ea GPON lapeng.Ha e le hantle, tt ke tsela e potlakileng ea hore re sebelise fiber ea GPON e nang le Telecom MSO.Inthanete ke e 'ngoe ea litlhoko tsa bohlokoa ka ho fetisisa ho lelapa le leng le le leng.GPON (1490nm/1310nm) kapa XGPON (1577nm/1270nm) ke mahlale a tsebahalang a thehiloeng ho fiber ho ea lapeng: optical line terminal (OLT), 1x32 kapa 1x64 kapa 1x128 PLC fiber splitter, ka tlase ho 20Km fiber network sebaka le o.
