Ukwakheka kwamadivayisi okuxhumana kwe-optical

Ukwakheka kweamadivayisi okuxhumana okubonakalayo

Uhlelo lokuxhumana olunegagasi lokukhanya njengesignali kanye ne-Optical fiber njengendlela yokudlulisa lubizwa ngokuthi uhlelo lokuxhumana lwe-Optical fiber. Izinzuzo zokuxhumana nge-optical fiber uma kuqhathaniswa nokuxhumana kwekhebula lendabuko kanye nokuxhumana okungenantambo yilezi: amandla amakhulu okuxhumana, ukulahlekelwa okuphansi kokudlulisa, ikhono eliqinile lokuphazamisa i-electromagnetic, ubumfihlo obuqinile, kanye nezinto zokusetshenziswa ze-optical fiber transmission medium yi-silicon dioxide enesitoreji esiningi. Ngaphezu kwalokho, i-optical fiber inezinzuzo zobukhulu obuncane, isisindo esincane kanye nezindleko eziphansi uma kuqhathaniswa nekhebula.
Umdwebo olandelayo ukhombisa izingxenye zesekethe elula ehlanganisiwe ye-photonic:i-laser, ukusetshenziswa kabusha kwe-optical kanye nedivayisi yokususa izinto eziningi,umshini wokuthola izithombefuthii-modulator.

Isakhiwo esiyisisekelo sohlelo lokuxhumana lwe-optical fiber bidirectional sihlanganisa: i-electrical transmitter, i-optical transmitter, i-transmission fiber, i-optical receiver kanye ne-electrical receiver.
Isignali kagesi esheshayo ifakwa ikhodi yi-transmitter kagesi iye kwi-optical transmitter, iguqulwe ibe yi-optical signals ngamadivayisi e-electro-optical njenge-Laser device (LD), bese ihlanganiswa ne-transmission fiber.
Ngemva kokudluliselwa kwesignali ye-optical ibanga elide nge-fiber yemodi eyodwa, i-amplifier ye-fiber efakwe i-erbium ingasetshenziswa ukukhulisa isignali ye-optical nokuqhubeka nokudluliselwa. Ngemva kokuphela kokwamukela kwe-optical, isignali ye-optical iguqulwa ibe isignali kagesi yi-PD namanye amadivayisi, futhi isignali yamukelwa yi-receiver kagesi ngokusebenzisa ukucubungula kagesi okulandelayo. Inqubo yokuthumela nokwamukela izimpawu ngakolunye uhlangothi iyafana.
Ukuze kufezwe ukwenziwa kwemishini ekuxhumaneni, i-optical transmitter kanye ne-optical receiver endaweni efanayo kuhlanganiswa kancane kancane kwi-optical Transceiver.
Isivinini esikhuluImojula ye-transceiver ebonakalayoyakhiwe yi-Receiver Optical Subassembly (ROSA; i-Transmitter Optical Subassembly (TOSA) emelelwa amadivayisi asebenzayo optical, amadivayisi angasebenzi, amasekethe asebenzayo kanye nezingxenye zesikhombimsebenzisi se-photoelectric ziyapakishwa. I-ROSA kanye ne-TOSA zipakishwa ngama-laser, ama-photodetector, njll. ngesimo sama-optical chips.

Ngenxa yezinkinga ezibonakalayo kanye nezinselele zobuchwepheshe ezihlangatshezwe ekuthuthukisweni kobuchwepheshe be-microelectronics, abantu baqala ukusebenzisa ama-photon njengabathwali bolwazi ukuze bafinyelele i-bandwidth enkulu, isivinini esiphezulu, ukusetshenziswa kwamandla okuphansi, kanye ne-low delay photonic inteated circuit (PIC). Umgomo obalulekile we-photonic integrated loop ukuqaphela ukuhlanganiswa kwemisebenzi yokukhiqiza ukukhanya, ukuxhuma, ukushintshashintsha, ukuhlunga, ukudlulisa, ukuthola nokunye. Amandla okuqala okushayela ama-photonic integrated circuits avela ekuxhumaneni kwedatha, bese ithuthukiswa kakhulu kuma-microwave photonics, ekucubungulweni kolwazi lwe-quantum, kuma-optics angewona aqondile, kuma-sensor, kuma-lidar nakwamanye amasimu.
