Njengamanje, baningi abakhiqizi bangaphandle nabasekhaya bei-fiber optic transceiversemakethe, futhi imigqa yemikhiqizo yabo icebile kakhulu. Izinhlobo ze-fiber optic transceivers nazo zihlukile, ikakhulukazi zihlukaniswe ngama-rack-mounted optical transceivers, ama-transceiver optical wedeskithophu kanye nama-transceiver optical ohlobo lwekhadi.

I-optical fibre transceiver iyiyunithi yokuguqula imidiya ye-Ethernet eshintshanisa amasiginali kagesi asontekile amabanga amafushane kanye namasiginali okubona amabanga amade. Ibizwa nangokuthi i-photoelectric converter ezindaweni eziningi futhi isetshenziswa kuimishini yokuxhumana optical.

Ibanzi kunobubanzi.Imishini yokudlulisa i-fiber optical njengama-transceiver optical ocingo kanye nemishini yokufinyelela i-fiber optical ingafinyelela ukudluliselwa phakathi kwamadivayisi ngama-transceivers optical. Ngokuvamile, ama-transceivers optical ahlukaniswe abe yimodi eyodwa kanye nemodi eminingi, i-fiber eyodwa kanye ne-dual-fiber. Uhlobo lwesixhumi esibonakalayo esimisiwe yi-SC. I-FC, LC, njll. kungabuye kulungiselelwe ngokwezidingo zamakhasimende. Ibanga lokudlulisela livamise ukuba ngamakhilomitha angama-25, amakhilomitha angama-40, amakhilomitha angama-60 nangama-80. , amakhilomitha angu-100, amakhilomitha angu-120, njll.

Ama-transceiver abonakalayo emodi eyodwa kanye namamodi amaningi

Imodi eyodwa isho ukuthi isignali yokubona isakaza ngesiteshi esisodwa, kuyilapho imodi ekabili noma imodi eminingi icishe ifane futhi isakazwa ngamashaneli amabili noma amashaneli amaningi. Uma umsebenzisi ekhetha ukuthi adlulise ngemodi eyodwa noma ngemodi eminingi, into eyinhloko enqumayo yibanga elidingwa ngumsebenzisi ukuze alidlulise. Ukudluliswa kwemodi eyodwa kunokuncishiswa okuncane, kodwa ijubane lokudlulisela lihamba kancane. Ilungele ukudluliswa kwebanga elide. Ngokuvamile, ibanga likhulu kunamamayela angu-5. Kungcono ukukhetha i-fiber yemodi eyodwa. Ukudluliswa kwe-Multimode kunokunciphisa okukhulu, kodwa isivinini sokudlulisela siyashesha. Ngokudluliswa kwebanga elifushane, ngokuvamile ibanga lingaphansi kwamamayela angu-5, futhi i-multimode fiber iyinketho engcono kakhulu.

I-fiber eyodwa kanye ne-dual fiber optical transceiver

I-Single fiber ibhekisela ku-fiber optical-core eyodwa edlulisela kumongo owodwa; i-dual fiber ibhekisela ku-double-core optical fiber edlulisela kuma-cores amabili, eyodwa eyamukelayo neyodwa idlulisela. Ngokuvamile, abasebenzisi bavame ukusebenzisai-dual-fiber, ngoba i-dual-fiber inenzuzo kakhulu ngokwenani. I-fiber eyodwa ngokuvamile isetshenziswa lapho intambo yokubona iqinile. Isibonelo, uma i-fiber engu-12-core iyi-dual-core, amanethiwekhi angu-6 kuphela angasakazwa; uma i-fiber eyi-12-corei-fiber eyodwa, 50% wezintambo zingagcinwa.

FC, SC, LC i-transceiver optical

I-FC, i-SC, ne-LC wuhlobo lwesixhumi esibonakalayo se-pigtail, futhi i-SC iyisixhumi esibonakalayo se-pigtail esisetshenziswa kakhulu. Lapho uthenga i-interface ye-optical transceiver, naka ukuthi ingabe lesi sixhumi esibonakalayo sifana nesixhumi esibonakalayo se-pigtail osinikezayo. Vele, kunezinhlobo eziningi zezintambo ezibonakalayo emakethe, njenge-FC ekugcineni kanye ne-SC ngakolunye uhlangothi.Amamojula we-SFP opticalzisetshenziswa kaningi ku-LC.

Ibanga lokudlulisela le-transceiver optical lincike ekukhetheni komsebenzisi ohlelweni lwangempela, futhi ibanga lokudlulisela phakathi kwamadivaysi amabili lingakhethwa ngokuvumelana ne-transceiver ebonakalayo ehambisanayo.

Isifinyezo: Lapho ukhetha i-fiber optical transceiver, qaphela ngokukhethekile isicelo. Uma i-transceiver ye-optical engalungile ikhethiwe, ingabangela ihhovisi noma i-transceiver optical yocingo ekude noma ezinye izinto zokusebenza ukuthi zingasebenzi kahle noma isixhumi esibonakalayo se-pigtail singaxhumeki. Inkinga enemininingwane ingaba Thintana nomkhiqizi ukuze uqinisekise ukuthi uthenga izimpahla ezifanele.
