Iyini i-fiber optic transceiver?

I-Fiber optic transceiver iyithuluzi elisetshenziselwa ukudlulisa amasignali optical ekuxhumaneni kwe-fiber optic. Iqukethe i-emitter yokukhanya (i-light emitting diode noma i-laser) kanye nesamukeli sokukhanya (umtshina wokukhanya), esetshenziselwa ukuguqula amasignali kagesi abe amasignali okubona kanye nokuwaguqulela emuva.

Ama-transceivers e-Fiber optic asebenza njengebhuloho phakathi kwezibonakaliso ze-optical kanye nogesi ezinhlelweni zokuxhumana ze-fiber optic, ukufeza ukudluliswa kwedatha ngesivinini esikhulu futhi ezinzile. Ingasetshenziswa kumanethiwekhi endawo (ama-LAN), amanethiwekhi endawo ebanzi (ama-WAN), ukuxhumana kwesikhungo sedatha, iziteshi eziyisisekelo zokuxhumana okungenantambo, amanethiwekhi ezinzwa, nezinye izimo zokudlulisa idatha ngesivinini esikhulu.

Umgomo wokusebenza:

I-Optical Transmitter: Uma isignali ye-elekthronikhi yamukelwe, umthombo wokukhanya (njenge-laser noma i-LED) ku-transmitter optical uyacushwa, ukhiqize isignali yokubona ehambisana nesiginali kagesi. Lezi zimpawu zokukhanya zidluliselwa ngemicu ye-optical, futhi imvamisa yazo kanye nendlela yokushintshashintsha inquma izinga ledatha kanye nohlobo lwephrothokholi yokudlulisela.

I-Optical receiver: I-optical receiver inesibopho sokuguqula amasignali okukhanya abuyele kuzimpawu zikagesi. Ngokuvamile isebenzisa ama-photodetectors (njengama-photodiodes noma ama-photoconductive diode), futhi lapho isignali yokukhanya ingena kumtshina, amandla okukhanya aguqulwa abe isignali kagesi. Umamukeli wehlisa isignali yokubona futhi ayiguqule ibe isignali yoqobo ye-elekthronikhi.

Izingxenye eziyinhloko:

● I-Optical Transmitter (Tx): inesibopho sokuguqula amasignali kagesi abe amasignali optical kanye nokudlulisa idatha ngokusebenzisa imicu yokubona.

● I-Optical Receiver (Rx): Ithola amasignali okubona ngakolunye uhlangothi lwefayibha futhi iwaguqulele emuva kuzimpawu zikagesi ukuze zicutshungulwe idivayisi eyamukelayo.

● Isixhumi se-Optical: sisetshenziselwa ukuxhuma ama-transceivers e-fiber optic nge-fiber optical, ukuqinisekisa ukuhanjiswa okuphumelelayo kwezibonakaliso ze-optical.

● Isekhethi yokulawula: isetshenziselwa ukuqapha isimo sesidlulisi se-optical nomamukeli, nokwenza izinguquko ezidingekayo zesignali kagesi nezilawuli.

Ama-transceivers e-Fiber optic ayahluka kuye ngezinga lawo lokudlulisela, ubude beza, uhlobo lwesixhumi esibonakalayo, namanye amapharamitha. Izinhlobo zokusebenzelana ezivamile zifaka i-SFP, i-SFP+, i-QSFP, i-QSFP+, i-CFP, njll. Uhlobo ngalunye lwesixhumi esibonakalayo lunesimo esithile sohlelo lokusebenza kanye nobubanzi bohlelo lokusebenza. Ama-transceivers e-Fiber optic asetshenziswa kakhulu emikhakheni yezokuxhumana yesimanje, ehlinzeka ngokusekelwa okubalulekile kwezobuchwepheshe kokudluliswa kwe-fiber optic ngesivinini esikhulu, ibanga elide, nokulahlekelwa okuphansi.
