Ukuhlaziywa Okuningiliziwe Kwekhebula Le-Fiber Optic Yemodi Eyodwa (SMF)

Ikhebula le-Single-Mode Fiber (SMF) liwubuchwepheshe obubalulekile ohlelweni lokuxhumana lwe-fiber optic, ethatha indawo engenakushintshwa ebangeni elide kanye nokudluliswa kwedatha ngesivinini esikhulu ngokusebenza kwayo okuhle kakhulu. Lesi sihloko sizokwethula isakhiwo, ukucaciswa kobuchwepheshe, izimo zohlelo lokusebenza nesimo semakethe Sekhebula Le-Fiber Lemodi Eyodwa ngokuningiliziwe.

Isakhiwo sentambo ye-fiber optic yemodi eyodwa

Inhliziyo yentambo ye-fiber optic yemodi eyodwa iyifayibha ngokwayo, equkethe umongo wengilazi ye-quartz kanye nokuvala ingilazi ye-quartz. I-fiber core ngokuvamile ingama-microns angu-8 kuya kwangu-10 ububanzi, kuyilapho ukuvala kucishe kube ngama-microns angu-125 ububanzi. Lo mklamo uvumela i-fiber yemodi eyodwa ukuthi idlulisele imodi eyodwa kuphela yokukhanya, ngaleyo ndlela igweme ukuhlakazeka kwemodi futhi iqinisekise ukudluliswa kwesignali yokwethembeka okuphezulu.

Imininingwane Yezobuchwepheshe

Izintambo ze-fiber optic zemodi eyodwa zisebenzisa ukukhanya kumaza wamaza ngokuyinhloko angu-1310 nm noma u-1550 nm, izifunda ezimbili zamaza amaza ezinokulahleka okuphansi kwefayibha, okuzenza zifanelekele ukudluliswa kwebanga elide. Amafayibha emodi eyodwa anokulahlekelwa amandla aphansi futhi awakhiqizi ukuhlakazeka, okuwenza afaneleke kumthamo ophezulu, ukuxhumana okude kwe-fiber optic. Ngokuvamile zidinga i-laser diode njengomthombo wokukhanya ukuze kuqinisekiswe ukudluliswa kwesignali okuzinzile.

Izimo zohlelo lokusebenza

Izintambo ze-fiber optic zemodi eyodwa zisetshenziswa ezimeni ezehlukene ngenxa yomkhawulokudonsa ophezulu nezici zokulahlekelwa okuphansi:

1. I-Wide Area Networks (WAN) kanye ne-Metropolitan Area Networks (MAN): Njengoba i-fiber yemodi eyodwa ingasekela amabanga okudlulisela amakhilomitha angafika kwamashumi, ilungele ukuxhuma amanethiwekhi phakathi kwamadolobha.
2. Izikhungo zedatha: Ngaphakathi kwezikhungo zedatha, imicu yemodi eyodwa isetshenziselwa ukuxhuma amaseva anesivinini esikhulu kanye nemishini yenethiwekhi ukuze kuhlinzekwe ukudluliswa kwedatha ngesivinini esikhulu.
3. I-Fiber to the Home (FTTH): Njengoba isidingo sokufinyelela ku-inthanethi ngesivinini esikhulu sikhula, amafayibha emodi eyodwa nawo ayasetshenziswa ukuhlinzeka ngamasevisi e-broadband yasekhaya.

I-Market Scenario

Ngokusho kweDatha Bridge Market Research, imakethe ye-fiber optics yemodi eyodwa kulindeleke ukuthi ibone ukukhula okubalulekile ngesilinganiso esingu-9.80% ngesikhathi sokubikezela sika-2020-2027. Lokhu kukhula kubangelwa ikakhulukazi izici ezifana nokuthuthukiswa kwamanethiwekhi okuxhumana angenantambo, ukwanda okuthandwayo kokuxhunywa kwe-fiber-to-the-home, ukwethulwa kwe-IoT, kanye nokuqaliswa kwe-5G. Ikakhulukazi eNyakatho Melika nase-Asia Pacific, imakethe ye-fiber optics yemodi eyodwa kulindeleke ukuthi ikhule ngenani elikhulu, elihambisana nokwamukelwa okuphezulu kobuchwepheshe bezokuxhumana obuthuthukile kanye nentuthuko esheshayo yezobuchwepheshe kulezi zifunda.

Isiphetho

Izintambo ze-fiber optic zemodi eyodwa zidlala indima ebalulekile ngokuya ngamanethiwekhi okuxhumana esimanje ngenxa yomkhawulokudonsa wawo ophezulu, ukulahlekelwa okuphansi, nokungaphazamiseki okuphezulu. Ngokuqhubeka okuqhubekayo kobuchwepheshe kanye nokukhula kwesidingo semakethe, uhla lokusetshenziswa kwezintambo ze-fiber optic zemodi eyodwa luzophinde lunwetshwe ukuze lunikeze ukwesekwa okuqinile kokudluliswa kwedatha ngesivinini esiphezulu emhlabeni jikelele.
