Kana setiraiti imwe ine ma transponder akapfuma, ma transponders anowanikwa panzvimbo mbiri: Vertical and Horizontal kana Left Hand Circular Polarity (LHCP) uye Right Hand Circular Polarity (RHCP). Yenguva dzose satellite inogamuchira inogona kuverenga iyo RF bandwidth ye950 ~ 2150MHz. Kune akawanda 32 transponders kubva 950MHz kusvika 2150MHz.
Twin LNB inogona kunge yakagadza LO frequency nesatellite MSO. Iwo maviri maRF akabuda ari Vertical (RHCP) uye Horizontal (LHCP), imwe neimwe ine bandwidth ye950 ~ 2150MHz. Kana iyo satellite yakazara transponder nhamba iri pasi pe64, tinogona kushandisa inotevera mhinduro kugovera iyi setiraiti zvirimo kuzviuru zvedzimba kuburikidza nefiber.
Mumufananidzo uri pamusoro, GLB3500A-2T optical transmitter inoshandura mapatya LNB RFs uye Terrestrial TV (174~700MHz) RF kuita imwe 1550nm fiber kubva padenga reimba. The optical kubuda kweGLB3500A-2Tinogona kutyaira 32pcs Optical receivers zvakananga nePLC fiber splitter, apo imweGLB2000AOptical receiver inopa satellite uye Terr TV masaini kune imwe STB neTV mune imwe imba,GLB3500A-2WROptical receiver inotsigira imwe Terr TV port kune akawanda-TV uye 4 akagara STBs mune imwe imba. Kana iyo nhamba yevanyoresa ichipfuura mazana kana zviuru munharaunda kana muguta, isu tichava neamwe optical amplifier GWA3530 mushure meGLB3500A-2T optical transmitter.GWA3530Optical amplifier ine 8 kana 16 kana 32 kana 64 chiteshi, chiteshi chega chega chinogona kutyaira gumi nematanhatu kana 32 kana makumi matanhatu nemana ekugamuchira. Mune mamwe mazwi, GWA3530 inogona kutyaira 1024 optical receivers kana 2048 optical receivers kana 4096 optical receivers mu20Km fiber kure. Iine sarudzo yeOLT yekupinza chiteshi, GWA3530 inogona kuisa satellite TV RF pamusoro peiyo fibre imwechete yeGPON kana XGPON network.
Zvakanakira satellite TV FTTH:
- Imwe yakagara ndiro yevanyoreri makumi matatu nevaviri kana zviuru zvevanyoresa
- Zvirinani Satellite chiratidzo chemhando pane yega fiber terminal
- Fiber terminal iri nyore kuisirwa mumaminetsi mashanu ne "plug uye tamba" dhizaini
- Regular satellite receiver
Kana paine zvinopfuura makumi matatu nembiri zvinotenderera setiraiti mune yega satellite polarity, bhendi rezasi uye bhendi repamusoro (pasi pe22KHz toni) zvinounzwa kuti zvisangane nesetiraiti inogamuchira 950MHz ~ 2150MHz frequency renji. Twin wideband LNBGWB104Gine 10.4GHz LO frequency uye RF inobuda bandwidth ye300MHz ~ 2350MHz, kureva, wideband Vertical RF yakaenzana neVertical Lower (VL) uye Vertical Higher (VH) ukuwo wideband Horizontal RF yakaenzana neHorizontal Lower (HL) uye Horizontal Higher (HH) ) Nekudaro, wideband RF bandwidth inodarika iyo RF bandwidth yesatellite inogamuchira, isu tinoda Digital Channel Satellite Switcher (dCSS) chip kushandura wideband RF mumhando yesatellite inogamuchira. Mukuwedzera, iyo satellite inogamuchira inofanirwa kutsigira unicable standard.
Mumufananidzo uri pamusoro,GLB3500E-2TOptical transmitter inoshandura twin wideband LNB RFs uye Terrestrial TV (Max 7ch VHF, 174 ~ 250MHz) RF kuita imwe 1550nm fiber kubva padenga reimba. Iyo yekuona kubuda kweGLB3500E-2T inogona kutyaira 32pcs optical inogamuchira zvakananga kana zviuru zveanogamuchira anogamuchira ne.GWA3530amplifier. Pafurati imwe neimwe, imweGLB3500E-2WROptical receiver inotsigira 4 unicable satellite inogamuchira.
MuEurope, kune anopfuura 7 DTT chiteshi (174 ~ 700MHz), isu tinotevera dhizaini yekugovera zvizere zvirimo zvesetiraiti (seHot Bird 13E) uye Maximum 28 DTT chiteshi.
Mumufananidzo uri pamusoro,GLB3500E-3TOptical transmitter inoshandura twin wideband LNB RFs uye Terrestrial TV (174~700MHz) RF kuita imwe 1550nm fiber kubva padenga reimba. Iyo yekuona kubuda kweGLB3500E-3T inogona kutyaira 32pcs optical inogamuchira zvakananga kana zviuru zveanogamuchira anogamuchira ne.GWA3530amplifier. Pafurati imwe neimwe, imweGLB3500-3WROptical receiver ine imwe Terr TV chiteshi cheakawanda-TV uye imwe yakagara chiteshi kune 4 unicable satellite inogamuchira.
