    Yese optical network mhinduro dzeredhiyo uye terevhizheni vanoshanda

    Nguva yekutumira: Mar-29-2023

    Parizvino, IPTV, iwo matatu makuru ekufambisa nhare, inogara ichinyura pamusika weTV musika wevatambi veredhiyo neterevhizheni. Maredhiyo neterevhizheni vakatarisana nehuwandu hwekurasikirwa nevashandisi, uye shanduko yekuvandudza redhiyo neterevhizheni yave pedyo. Zvinogona kutaurwa kuti ani nani anodzora imba yekutandarira anobata vashandisi. Bhizinesi guru revashandisi veredhiyo neterevhizheni rinosanganisira ese maredhiyo neterevhizheni masevhisi uye maviri-nzira data masevhisi (Internet access/VOD/IPTV/e-government/interactive games) pamwe nebroadband services. Naizvozvo, kuvakwa kweFTTH yeredhiyo uye terevhizheni kunosanganisira kuvakwa kweFTTH yeredhiyo neterevhizheni masevhisi uye kuvakwa kweFTTH kune maviri-nzira data masevhisi. Kubatanidza zviwanikwa zveredhiyo neterevhizheni, kuitwa kweFTTH kunonyanya kutora mhinduro iripo muindasitiri iyi: single fiber three wave + Broadband service access solution. Nhasi, mupepeti achakutsanangurira zvakanyanya.

    Mune imwechete fiber three wave +broadband service access scheme, iyoONUOptical cat data chikamu chinoshandisa 1310nm/1490nm optical zviratidzo, uyeONUCATV chikamu chinoshandisa 1550nm optical masaini. Mukamuri reredhiyo neterevhizheni kumberi-kumberi, iyo WDM wavelength division multiplexing michina inosanganiswa netambo yefiber optic, uye yobva yapfuura nemukutapurirana uye kupatsanurwa kwemaziso kwemazinga akasiyana emidziyo yeODN isati yasvika kumba kwemushandisi. MuONUOptical cat unit yemusha wemushandisi, iyo imwechete fiber matatu waveONUCATV yakagadziridzwa nekambani yedu inoshandiswa, kureva, data + CATV optical uye mechanika maviri mune imwe GPON.ONU, iyo inogona kuburitsa zvakananga nhepfenyuro yeterevhizheni masaini uye Broadband data masaini. Panguva imwecheteyo, veredhiyo neterevhizheni vanogona zvakare kuvandudza vashandisi veBroadband zvichienderana nechirongwa ichi, kuwana mari yakawanda-yekuwana mari, uye kuderedza mari yekuvaka network.

    Mabhenefiti eiyo imwechete fiber matatu wave yekuwana chirongwa ndeaya anotevera:

    1. Kuguma-kusvika-kumagumo manejimendi: Nekuda kwekuguma-kusvika-kumagumo network architecture yeimwe fiber matatu wave, zviri nyore kwazvo kubata.ONUoptical katsi. Maneja maneja anogona kuita mashandiro akadai serekure sevhisi kugovera, kugadzirisa kukanganisa, uye kuvhura / kuvhara CATV masevhisi kuburikidza nemberi-kumagumo.OLTzvishandiso.

    2. Mutengo wakaderera weODN: Nekuti nhepfenyuro yeTV masaini uye Broadband data masiginecha anofambiswa pane imwecheteyo yemuviri optical fiber, chirongwa ichi chinoderedza zvakanyanya mutengo wekuvaka weODN zviwanikwa kubva kumberi-kumberi kuenda kumusha wemushandisi.
