Ukwakheka kwamadivayisi wokuxhumana we-Optical

Ukwakheka kweAmadivayisi wokuxhumana we-Optical

Uhlelo lokuxhumana olunamagagasi akhanyayo njengesiginali kanye nefayibha ye-optical njengoba okuhambisa i-medium kubizwa ngokuthi uhlelo lokuxhumana lwe-fiber optical fiber. Izinzuzo zokuxhumana nge-fiber okuqhathaniswa nokuxhumana kwe-cable yendabuko kanye nokuxhumana okungenantambo yilezi: umthamo omkhulu wokuxhumana, amandla okuhambisa aphezulu, kanye nokuqukethwe okunamandla okudluliselwa kwe-fiber okujwayelekile yi-silicon dioxide enesitoreji esiningi. Ngaphezu kwalokho, i-Optical Fiber inezinzuzo zobukhulu obuncane, isisindo esikhanyayo nezindleko eziphansi uma kuqhathaniswa nentambo.
Umdwebo olandelayo ukhombisa izingxenye ze-Photonic Companimed Circleit Elula:i-laser, Ukuphinda usebenzise kabusha kanye nedivayisi ye-demiltubiling,I-PhotoDETETETETECETETETna-imbebula.

Isakhiwo esiyisisekelo sohlelo lokuxhumana lwe-Optical Fiber Binidirectional System lubandakanya: Umshumeli kagesi, ukudluliselwa kwe-Optical Transmitter, i-fiber yokuhambisa, owemukelayo we-optical kanye nerekeli kagesi.
Isiginali kagesi enesivinini esiphakeme ikhonjwe yi-Transmitter kagesi eya e-Optical Transmitter, iguqulwe yaba yizimpawu zokubona ngamadivayisi we-electro-optical afana ne-laser device (ld), bese kuthi kufakwe kwifayibha yokuhambisa.
Ngemuva kokudluliswa kwebanga elide kwesiginali ye-Optical ngokusebenzisa i-single-mode fiber, i-erbium-doped fiber amplifier ingasetshenziselwa ukukhulisa isinali ye-optical futhi uqhubeke nokudluliswa. Ngemuva kokuphela kokuthola okutholayo, isibonakaliso sokubona siguqulwa sibe yisiginali kagesi nge-PD namanye amadivaysi, futhi isiginali itholwa ngumemukeli kagesi ngokusebenza kukagesi okulandelayo. Inqubo yokuthumela nokwamukela amasiginali kwelinye icala liyafana.
Ukuze uzuze ukulungiswa kwemishini kusixhumanisi, ukudluliselwa kwe-Optical Transmitter kanye nokwamukela okubonakalayo endaweni efanayo kuhlanganiswe kancane kancane ku-transceiver ye-Optical.
Ijubane eliphakemeImodyuli ye-Optical TransceiverIhlanganiswe nge-Optical Optical Subasmbly (Rosa; Transmitter Optical Subasmbly (TOSA) emelelwa amadivayisi asebenzayo asebenzayo, amadivaysi atholakalayo, amasekethe asebenzayo kanye ne-TOSA ahlanganiswe ama-lasers, photodeters, njll. Ngefomu lama-chip we-optical.

Lapho ebhekene nezinselelo zeBottleneck nezobuchwepheshe ezihlangabezana nazo ekwakhiweni kobuchwepheshe beMicroelectorics, abantu baqala ukusebenzisa ama-photons njengezithwali zolwazi ukuze bafinyelele umkhawulokudonsa omkhulu, isivinini esiphakeme, kanye nokulibala okuphansi kwe-Photonic Photonic (PIC). Umgomo obalulekile we-Photonic Integrated Loop ukubona ukuhlanganiswa kwemisebenzi yesizukulwane esingu-Coupling, ukuguquguquka, ukuhlunga, ukuhlunga, ukuhambisa, ukutholwa nokunye. Amandla okuqala okushayela we-Photonic Okuhlanganisiwe Amasekethe aqhamuka ekuxhumaneni kwedatha, bese kukhuliswa kakhulu e-microwave Photonics, ukucubungula imininingwane ye-quantum, ama-nonlinear Optics, izinzwa, i-lindidar kanye nezinye izinkambu.
