    Optical Network Terminal

    Nthawi yotumiza: Dec-19-2023

    Optical network terminal (yomwe imadziwika kuti Optical cat kapena Optical modem), imatanthawuza kufalikira kudzera mu th.e CHIKWANGWANI sing'anga, kusinthasintha kwa siginecha ndi kutsitsa kwa ma protocol ena a zida za netiweki. Chipangizo cha Lightcat chimagwira ntchito ngati chida chotumizira ma netiweki akuluakulu amderali, maukonde am'mizinda yayikulu komanso ma network amdera lonse. Mosiyana ndi transceiver optical, transceiver optical amangolandira ndi kutulutsa kuwala, ndipo samaphatikizapo kutembenuka kwa protocol.

    Modem ndi chipangizo chamagetsi chomwe chimasinthira siginecha ya digito kupita ku siginecha ya analogi kuti itumizidwe, ndikutsitsa chizindikiro cha analogi cholandilidwa kuti mupeze chizindikiro cha digito. Cholinga chake ndi kupanga chizindikiro cha analogi chomwe chingathe kufalikira mosavuta ndikubwezeretsanso digito yoyambiriral chizindikiro ndi decoding. Kutengera kugwiritsa ntchito, MODEM imatha kugwiritsa ntchito njira zosiyanasiyana zotumizira ma analogi, monga ma fiber optics, wailesi ya RF, kapena matelefoni.

    Ma modemu a foni omwe amagwiritsa ntchito bandi yomvera ya mzere wamba wa foni yolumikizana ndi data ndi most ambiri amakumana modemu. M'Chingerezi cholankhulidwa, anthu ambiri amatchula modemu ya foni kuti "mphaka" kapena "matsenga" potengera silabi yoyamba ya katchulidwe ka Chingerezi.

    Ma modemu ena odziwika amaphatikizapo ma modemu a chingwe ofikira ma data ambiri, ma modemu a ADSL, ndi ma modemu a fiber. Foni yam'manja ya digito ndi modemu yopanda zingwe. Zipangizo zamakono zotumizira mauthenga zimapangidwira kusamutsa chidziwitso chochuluka pamtunda wautali pazinthu zosiyanasiyana, choncho zimachokeranso pa ntchito ya modem. Ma modemu a Microwave atha kugwiritsidwa ntchito pa mamiliyoni a bits pamphindikati. The modemu kuwala pogwiritsa ntchito CHIKWANGWANI kuwala monga sing'anga kufala akhoza kufika oposa makumi a Gbps, tsopano ndi msana wa telecommunications kufala Passive kuwala network (Passive kuwala network), wotchedwanso passive kuwala CHIKWANGWANI network, ndi mtundu wa kuwala CHIKWANGWANI kulankhulana. netiweki, yomwe imadziwika kuti palibe magetsi kuti amalize kukonza ma siginecha, ngati galasi kunyumba, safuna magetsi kuti awonetse chithunzicho, kuwonjezera pa zida zogwiritsira ntchito magetsi, ma node omwe ali pakati amapangidwa ndi tinthu tating'onoting'ono ta fiber optic.

    Malinga ndi lingaliro la New Generation Network (NGN), maukonde olumikizirana ma telecommunication amatha kugawidwa m'magawo awiri: core network ndi network network. Netiweki yapakati ndi yofanana ndi mizere yanthawi zonse yolumikizirana ndi mtunda wautali. Netiweki yofikira ili ndi mphete ya zingwe za fiber optic. Ntchito za ma netiweki oyambira ndi maukonde ofikira ndizosiyana, ndipo mawonekedwe awo amapatsirananso ndi osiyana. Chifukwa chake, mapulogalamu a PON atha kugawidwa m'mitundu iwiri: PON ya core network ndi PON network network. Zakale zimachokera ku WDM, ndipo zotsirizirazi zimagwiritsa ntchito diverter optical ndi WDM.

    Zomwe zili pamwambazi ndi kufotokozera mwachidule za optical network terminal yobweretsedwa ndi Shenzhen HDV Phoelectron Technology LTD., yomwe ndi opanga okhazikika pazida zoyankhulirana monga zida zake zazikulu. Zida zawo zogwirizana ndi:oltinu/ wanzeruinu/cinu/ fiberinu/ kambainu/gpoinu/xponinu/ oltzida/oltkusintha/gpoolt/epooltndi zina zotero, alandileni ogwiritsa ntchito kuti abwere ku zokambirana zamalonda.
