    Isithombe sibonisa ukuthi iyini i-fiber? Ukuhlukaniswa kwemicu ye-optical?

    Isikhathi sokuthumela: Mar-27-2020

    I-1.optical fibre core structure

    001

    I-1) Ingqikithi: inkomba ephezulu ye-refractive, esetshenziselwa ukudlulisa ukukhanya;

    I-2) I-Cladding: inkomba ephansi ye-refractive, eyenza isimo sokubonisa ngokuphelele ngengqikithi;

    3) Isendlalelo esivikelayo: sivikela i-fiber optical.

    2.Imodi eyodwa kanye nemodi eminingi

    003

    Imodi eyodwa kuphela yokukhanya engadluliswa. Ngakho-ke, ukuhlakazeka kwayo kwemodi ephakathi kuncane futhi kulungele ukuxhumana okukude, kodwa kukhona nokuhlakazwa kwezinto ezibonakalayo kanye nokuhlakazeka kwe-waveguide. Ngale ndlela, i-fiber yemodi eyodwa inezidingo eziphakeme zobubanzi be-spectral nokuzinza komthombo wokukhanya, okungukuthi, ububanzi be-spectral kumele bube buncane futhi ukuzinza Kungcono. Ifayibha yemodi eyodwa ayinakho ukuhlakazeka okuphelele.

    Ingadlulisela amamodi amaningi okukhanya. Kodwa-ke, ukuhlakazeka kwayo kwe-inter-mode kukhulu, okukhawulela imvamisa yokudlulisa amasignali edijithali, futhi kuzoba kubi kakhulu ngebanga elikhulayo. Ibanga lokudluliswa kwefayibha yemodi eminingi lifushane, ngokuvamile lingamakhilomitha ambalwa kuphela.

    Isisetshenziswa semodi eyodwa ngokuvamile singasebenza ngefayibha yemodi eyodwa noma ifayibha yemodi eminingi, kuyilapho okokusebenza kwemodi eminingi kukhawulelwe ekusebenzeni ngefayibha enemodi eminingi.
