Kukuphi ukusetshenziswa kwe-single/multimode fibre kanye ne-single/multimode optical module?

(1) I-fiber yemodi eyodwa ingenza i-fiber idluliselwe ngqo esikhungweni, futhi ngokuvamile isetshenziselwa ukudlulisa idatha ebangeni elide; ku-multi-mode fiber, amasignali optical asakazeka eziteshini eziningi, ngakho-ke i-fiber yemodi eminingi ivame ukusetshenziselwa ukudluliswa kwedatha yebanga elifushane.

(2) Amamojula abonakalayo emodi eyodwa avame ukusetshenziswa kumanethiwekhi ezindawo zedolobha elikude kanye nezinga eliphezulu lokudlulisela; amamojula e-multi-mode optical asetshenziswa ekudluliseni ibanga elifushane

Ingabe imicu yokubona yemodi eyodwa/yemodi eminingi ingaxutshwa namamojula emodi eyodwa/amamojula emodi eminingi?

Ngokuvamile, ukusebenza okuvamile kwe-fiber kanye ne-module optical kungaqinisekiswa kuphela ngokufanisa i-fiber kanye ne-module optical. Nakuba i-module eyodwa ingasebenza ku-fiber ye-multimode, kuzoba nokulahlekelwa kwephaketheni okuningi, ngakho-ke usadinga ukunaka ukuhambisana kwe-fiber kanye ne-optical module.

Ingabe i-multi-mode fiber kanye nemojuli ye-optical yemodi eyodwa ingasetshenziswa ndawonye?

Cha, kuthebula lomphumela wokuhlola ngenhla, singabona ukuthi imojula eyodwa ku-multimode fiber ibonakala ikwazi ukusebenza kude, kodwa empeleni umphumela wayo wokusebenza awukwazi ukuqinisekiswa. Ngakho-ke, kungcono ukusebenzisa i-multimode fiber ene-multimode optical module. Kusetshenziswe ndawonye, ​​ngoba iziguquli zemodi eminingi kanye nemodi eyodwa kumele zibe nobude obuhambisanayo be-wavelength nomsebenzi we-optical transceiver ukuze kuzuzwe umsebenzi wokuguqula izithombe zikagesi kanye nomthelela.

Kafushane: Okokugcina, ake sifingqe ukuthi umehluko phakathi kwefayibha eyodwa/multimode ikakhulukazi usebangeni lokudlulisela, imodi yokudlulisela kanye nezindleko; amamojula we-single/multimode optical adinga ukusetshenziswa namafiber optical futhi awakwazi ukuxutshwa.
