Ukuba isathelayithi enye inee-transponders ezityebileyo, ii-transponders zifumaneka kwiipolarities ezimbini: I-Polarity yeSetyhula yeSangqa eNqabileyo okanye eHorizontal okanye eKhohlo (LHCP) kunye nePolarity yeSetyhula yeSangqa (RHCP). Umamkeli wesathelayithi oqhelekileyo unokufunda i-RF bandwidth ye-950 ~ 2150MHz. Kukho ubuninzi be-32 transponders ukusuka kwi-950MHz ukuya kwi-2150MHz.
I-Twin LNB isenokuba iqeshe i-LO frequency kwi-satellite MSO. Iziphumo ezimbini zeRF zithe nkqo (RHCP) kunye neHorizontal (LHCP), nganye ine-bandwidth ye-950~2150MHz. Ukuba inani elipheleleyo lesathelayithi le-transponder lingaphantsi kwe-64, sinokusebenzisa isisombululo esilandelayo ukusabalalisa le mixholo yesathelayithi kumawaka amakhaya ngefayibha.
Kulo mzobo ungentla, i-GLB3500A-2T isidluliseli esibonakalayo siguqula amawele e-LNB RFs kunye neTerrestrial TV (174~700MHz) RF ibe yifayibha enye ye-1550nm kuphahla lwesakhiwo esinye. Imveliso ye-optical yeGLB3500A-2Tinokuqhuba i-32pcs i-optical receivers ngqo nge-PLC fiber splitter, apho enyeGLB2000Ai-optical receiver inikezela ngesathelayithi kunye neTerr imiqondiso yeTV kwi-STB enye kunye nomabonakude kwigumbi elinye,GLB3500A-2WRi-optical receiver ixhasa i-port ye-Terr ye-TV yee-TV ezininzi kunye ne-4 yahlala ii-STB kwindawo enye. Ukuba inombolo yomrhumi ingaphezulu kwamakhulu okanye amawaka kuluntu okanye esixekweni, siya kuba neamplifier enye ye-GWA3530 emva kwe-GLB3500A-2T isidluliseli esibonakalayo.GWA3530iamplifier optical has 8 okanye 16 okanye 32 okanye 64 port, izibuko ngalinye unako ukuqhuba 16 okanye 32 okanye 64 abamkeli optical. Ngamanye amagama, i-GWA3530 inokuqhuba i-1024 i-optical receivers okanye i-2048 i-optical receivers okanye i-4096 i-optical receivers kwi-20Km umgama wefiber. Ngokhetho lokufaka izibuko le-OLT, i-GWA3530 inokufaka i-TV yesathelayithi iRF phezu kwefayibha enye yeGPON okanye i-XGPON network.
Izinto eziluncedo kwisathelayithi TV FTTH:
- Esinye sahlala isitya sababhalisi be-32 okanye amawaka ababhalisile
- Umgangatho ongcono wesignali yeSatellite kwi-fiber terminal nganye
- I-Fiber terminal ilula ukufakwa kwimizuzu emi-5 ngoyilo lwe "plug and play".
- Umamkeli wesathelayithi oqhelekileyo
Ukuba kukho ngaphezu kwe-32 ye-satellite transponders kwi-polarity yesathelayithi nganye, ibhendi esezantsi kunye nebhendi ephezulu (phantsi kwethowuni ye-22KHz) yaziswa ukuhlangabezana ne-satellite receiver rhoqo 950MHz ~ 2150MHz uluhlu lwamaza. I-Twin wideband LNBGWB104Gine-10.4GHz LO frequency kunye ne-RF ye-bandwidth yemveliso ye-300MHz ~ 2350MHz, okt, i-wideband Vertical RF ilingana ne-Vertical Lower (VL) kunye ne-Vertical Higher (VH) ngelixa i-wideband Horizontal RF ilingana ne-Horizontal Lower (HL) kunye ne-Horizontal Higher (HH) ). Nangona kunjalo, i-wideband ye-RF ye-wideband ingaphaya kwe-RF ye-satellite receiver, sifuna i-chip ye-Digital Channel Satellite Switcher (dCSS) ukuguqula i-RF ebanzi kuluhlu lwe-satellite receiver. Ukongeza, umamkeli wesathelayithi kufuneka axhase umgangatho ongaguqukiyo.
Kulo mzobo ungentla,GLB3500E-2Ti-optical transmitter iguqula i-twin wideband LNB RFs kunye neTerrestrial TV (Max 7ch VHF, 174~250MHz) iRF ibe yifayibha enye ye-1550nm kuphahla lwesakhiwo esinye. Imveliso ye-GLB3500E-2T iyakwazi ukuqhuba ii-32pcs zamkeli zamehlo ngokuthe ngqo okanye amawaka-waka abamkeli bamehloGWA3530isandisi-lizwi. Kwindlu nganye, enyeGLB3500E-2WRi-optical receiver ixhasa i-4 unicable receiver satellite.
EYurophu, kukho ngaphezu kwe-7 DTT channels (174 ~ 700MHz), sinomzobo olandelayo ukusabalalisa imixholo epheleleyo yesathelayithi (njenge-Hot Bird 13E) kunye ne-Maximum 28 DTT channels.
Kulo mzobo ungentla,GLB3500E-3Ti-optical transmitter iguqula i-twin wideband LNB RFs kunye neTerrestrial TV (174~700MHz) iRF ibe yifayibha enye ye-1550nm kuphahla lwesakhiwo esinye. Imveliso ye-GLB3500E-3T ye-Optical inokuqhuba i-32pcs i-optical receiver ngokuthe ngqo okanye amawaka-waka abamkeli be-optical ngoku.GWA3530isandisi-lizwi. Kwindlu nganye, enyeGLB3500-3WRi-optical receiver ine-port ye-Terr ye-TV yee-multi-TV kunye ne-port enye ehleliyo ye-4 unicable satellite receivers.
