Sei kuisa Satellite pamusoro peGPON
Yakananga Nhepfenyuro Satellite (DBS) uye Yakananga Kumba (DTH) ndiyo inonyanya kufarirwa nzira yekunakidzwa nesatellite TV pasi rese. Kuti uzviite, satellite antenna, coaxial tambo, splitter kana multi-switcher uye satellite inogamuchira inodiwa. Nekudaro, kuisa satellite antenna kunogona kunetsa kune vanyoreri vanogara mudzimba. SMATV (satellite master antenna TV) mhinduro yakanaka kune vanhu vanogara muchivakwa kana nharaunda kuti vagovane imwe setiraiti dish uye terrestrial TV antenna. Iine fiber tambo, SMATV RF siginecha inogona kuendeswa ku20Km kure kana kugoverwa kudzimba makumi matatu nembiri zvakananga, ku320 kana 3200 kana 32000 dzimba kuburikidza neGWA3530 fiber optic amplifier.
Izvi zvinoreva here setiraiti MSO kana setiraiti system yekubatanidza inofanirwa kuisa yakavanzika fiber tambo kune wese anonyoresa? Ehe, isu tinoda fiber kune wese anonyoresa kana tichikwanisa, asi hazvidiwi kana paine GPON faibha kumba kare. Muchokwadi, tt inzira inokurumidza yekuti isu tishandise GPON faibha yeTelecom MSO. Internet ndechimwe chezvinhu zvakakosha zvinodiwa kumhuri yese. GPON (1490nm/1310nm) kana XGPON (1577nm/1270nm) ndiwo matekinoroji anozivikanwa akavakirwa pafayibha kuenda kumba: one optical line terminal (OLT), 1x32 kana 1x64 kana 1x128 PLC fiber splitter, isingasviki 20Km fiber network kureba uye o. (ONU) mumhuri, imwechete network topology yatinoda. Satellite chiratidzo chinotakurwa pa1550nm optical hwindo, isu tinongoisa OLT fiber paGWA3530 1550nm optical amplifier OLT port, usaite chinhu paPLC splitter uye fiber tambo. Pamba yega yega yevanyoresa tinoshandisa imwe SC/UPC kuenda kuSC/UPC fiber jumper pamwe chete neOptical LNB kuenda kuONU, ipapo setiraiti RF kubasa rega rega repamba rinogona kuitwa mumaminetsi mashanu.
Muchidimbu, tinogona kuisa fiber kumba yega yega yesatellite TV munharaunda ine mazana evanyoresa. Mutaundi rezviuru zvevanyoreri kana muguta remazana ezviuru zvevanyoreri, kuisa satellite TV pamusoro peGPON faibha ringave bhizinesi rinoshanda uye rine pundutso kune vese satellite operator uye GPON operator.
Telecom MSO inoda kugovera iyo GPON fiber? Zvinogona kuva zvakaoma uye zvinogona kuva nyore. GPON ine 2.5Gbps pasi hova kusvika 32 kana 64 kana 128 vanyoreri uko IPTV kana OTT vhidhiyo inoshandisa yakawanda yebandwidth. Iyo OTT yakadai seNetflix nezvimwewo haibhadhare sendi kuGPON MSO yemuno uye kune mamwe maOTT kunze kweNetflix. Satellite TV inonyanya kukwezva nekuda kwezviri mukati. Kana satellite opareta achida kugovera mari yemwedzi nemwedzi neGPON opareta, satellite opareta anogona kunge aine 30K, kana 300K yekuwedzera vanyoreri munguva pfupi (ava vanyoreri havagone kuisa satellite ndiro); uye GPON mushandisi anogona kuve neadd-added service kune avo vakanyoresa uye anovandudza kunaka kwesevhisi yeinternet.
