    Ukudlulisa Okukhanyayo

    Isikhathi sokuthumela: Dec-25-2023

    Ukudluliswa kwe-Optical ubuchwepheshe bokudlulisa ngendlela yamasignali optical phakathi komthumeli nomamukeli. Imishini yokudlulisa amehlo iwukuguqula amasiginali ahlukahlukene abe amasignali optical emishinini yokudlulisa i-fiber optical, ngakho okokusebenza kwesimanjemanje kokudlulisa amehlo kuvame ukusetshenziswa kufiber optical. Imishini yokudlulisa amehlo esetshenziswa kakhulu yilena: i-optical transceiver, i-Optical MODEM, i-optical transceiver, i-opticalshintsha, i-PDH, i-SDH, i-PTN nezinye izinhlobo zemishini.

    Isethulo esifushane sobuchwepheshe bokudlulisa amehlo

    I-Synchronous Optical Network (SONET) kanye ne-Synchronous Digital Hierarchy (SDH) : Isistimu yokudlulisa i-fiber optic (yangaphambili iyindinganiso yaseMelika esetshenziswa eNyakatho Melika, lena yokugcina indinganiso yamazwe ngamazwe). Kuthatha imojula yokudlulisa evumelanisiwe (STM-1,155Mbps) njengomqondo oyisisekelo. Imojula yakhiwe umthwalo wolwazi oluphelele, ingxenye engaphezulu, kanye nesikhombi seyunithi yokuphatha. Isici sayo esivelele sihambisana nesistimu ehlukahlukene ye-PDH.

    I-Plesiochronous Digital Hierarchy (PDH) : Isistimu yokudlulisa yedijithali yangaphambi kwe-SONET/SDH, imishini yokudlulisa engabonwa ngamehlo. Iklanyelwe ngokuyinhloko ukuxhumana ngezwi. Asikho isilinganiso esijwayelekile sesignali yedijithali kanye nesakhiwo sohlaka, futhi ukuxhumana kwamazwe ngamazwe kunzima.

    I-Wavelength Division Multiplex (WDM) : Ngokuyinhloko, i-Frequency Division Multiplex (FDM) isetshenziswa kuma-optical fibers, okungukuthi, ubuchwepheshe be-FDM kusizinda sokukhanya. Kuyindlela ephumelelayo yokuthuthukisa amandla okuxhumana kwe-fiber optical. Ukuze kusetshenziswe ngokugcwele izinsiza ezinkulu zomkhawulokudonsa endaweni yokulahlekelwa okuphansi kwe-fiber yemodi eyodwa, ifasitela elilahlekelwa kancane le-fiber lihlukaniswa ngamashaneli amaningana ngokuvumelana nemvamisa ehlukene (noma ubude be-wavelength) yesiteshi ngasinye. Badlulisa imilayezo yabo ngamaza ahlukene, ngakho abaphambanisani ngisho naku-fiber efanayo. I-Dense Wavelength Division Multiplex (DWDM) : Ngokungafani nezinhlelo ezivamile ze-WDM, izinhlelo ze-DWDM zinezikhala zesiteshi esincane kanye nokusetshenziswa okungcono komkhawulokudonsa.

    I-Optical Add/Drop Multiplex (OADM) : Idivayisi esebenzisa isihlungi esibonayo noma isihlukanisi ukuze ifake noma ihlukanise amasignali okubona kusukela kusixhumanisi sokudlulisa se-wavelength division multiplexing. I-OADM inamasiginali we-wavelength optical kusistimu ye-WDM ukukhetha izinga elingaphezulu/elingezansi elidingekayo, ifomethi kanye nohlobo lwephrothokholi. Isignali ye-wavelength edingekayo kuphela ithentwa/ifakwe endaweni, futhi amanye amasiginali we-wavelength abonakala ngokubonakalayo ngenodi. I-Dynamic (eguquguqukayo, elungisekayo noma ehlelekayo) I-OADM iyisisekelo sokufezekiswa kwamanethiwekhi okukhanya edolobha elikhulu. Isebenzisa i-OADM eguquguqukayo kumanethiwekhi okukhala kwe-inter-local optical, isistimu ingahlinzeka ngoxhumano olugcwele lwe-wavelength yesiteshi phakathi kwanoma yimaphi amanodi amabili.

    I-Optical cross interconnection (OpticalCross-connect, OXC): Izinsiza ezisetshenziselwa i-optical fibre network node, ngokuxhumeka okuphambanayo kwamasignali optical, kuyindlela ebalulekile yokufinyelela ukuvikelwa kwenethiwekhi okuthembekile / ukutakula kanye nezintambo ezizenzakalelayo nokuqapha. Ikakhulukazi yakhiwe ubuchwepheshe be-WDM kanye nobuchwepheshe bokuhlukanisa umoya obonakalayo (opticalshintsha).

    Yonke inethiwekhi ye-Optical (AON) : ibhekisela ohlelweni lwenethiwekhi lapho isignali ishintsha kuphela ugesi/i-optical kanye ne-optical/electric lapho ingena futhi iphuma kunethiwekhi, futhi ihlala ikhona ngendlela yokukhanya ngesikhathi sokudlulisa nokushintshanisa inethiwekhi. Ngamanye amazwi, ulwazi luhlala lusendaweni ye-optical ngesikhathi sokudluliselwa kwalo kusuka endaweni yomthombo kuya endaweni okuyiwa kuyo, futhi ubude begagasi buba iyunithi eyisisekelo kakhulu yenethiwekhi ye-optical yonke. Inethiwekhi ye-all-optical isobala kusiginali ngoba konke ukudluliswa kwesiginali kwenziwa kusizinda se-optical. Inethiwekhi ye-all-optical ibona umzila ngedivayisi yokukhetha ubude beza. Inethiwekhi ye-All-optical network isibe yisinqumo sokuqala senethiwekhi ye-broadband yesizukulwane esilandelayo esinesivinini esikhulu (i-ultra-high-speed) ngenxa yokungafihli kahle kwayo, izici zomzila wamaza wamaza, ukuhambisana nokukaleka.

    I-Li-Fi: Lobu buchwepheshe bokuxhumana obubonakalayo busebenzisa amaza okukhanya angaphakathi asekelwe ku-LED esikhundleni samaza omsakazo ukuze kudluliselwe idatha. Futhi amaqembu aphezulu ocwaningweni lwe-Li-Fi abheke ngale kwamaledi okudluliselwa kwedatha, okuwubuchwepheshe bokuxhumana obusekelwe nge-laser be-Li-Fi, obungathuthukisa ngokunengqondo izinga le-Li-Fi ngaphezu kwe-LED izikhathi ezingaphezu kweziyi-10. (Eqinisweni, eminyakeni embalwa edlule, ukudluliswa kwamanzi ngaphansi kwamanzi okuthuthukiswe yi-China Huako, i-United States kanye ne-Iran yakwazi ukukhuphula izinga lokungenazintambo kuya ku-300Gb/s ebangeni eliyimitha elingu-1. Indawo esetshenziswayo umoya.)

    Okungenhla yisingeniso esifushane solwazi oluyisisekelo lokudluliswa kwe-optical. Ngikholwa ukuthi uqondisisile ukuthi buyini ubuchwepheshe bokudlulisa amehlo ngale ncazelo emfushane engenhla. I-Shenzhen HDV Phoelectron Technology LTD ingumkhiqizi onguchwepheshe bemishini yokuxhumana ebonakalayo njengemikhiqizo eyinhloko. Ukuze kuhlinzekwe isevisi yekhwalithi engcono kumakhasimende ethu, ifakwe ithimba lezobuchwepheshe eliqinile nelihle kakhulu le-R & D. Imikhiqizo esemqoka yenkampani yileOLTI-ONU/ ACONU/ imojuli yokubona yokuxhumana/imojula yokubona yokuxhumana/OLTimishini/Ethernetshintshanokunye, ukuhlinzeka ngamasevisi ahlobene ngezidingo ezahlukahlukene zamakhasimende, wamukelekile ukuba khona kwakho.
