Imiterere yaibikoresho by'itumanaho rya optique

Sisitemu y'itumanaho ifite urumuri nk'ikimenyetso na fibre optique nk'uburyo bwo kohereza ubutumwa yitwa sisitemu y'itumanaho ya fibre optique. Ibyiza byo kohereza ubutumwa kuri fibre optique ugereranije n'itumanaho risanzwe rya insinga n'itumanaho ridafite umugozi ni: ubushobozi bwinshi bwo kohereza ubutumwa, gutakaza ubushobozi bwo kohereza ubutumwa, ubushobozi bukomeye bwo kurwanya amashanyarazi, ibanga rikomeye, n'ibikoresho fatizo by'uburyo bwo kohereza ubutumwa kuri fibre optique ni dioxyde silicone ifite ububiko bwinshi. Byongeye kandi, fibre optique ifite ibyiza byo kuba nto, uburemere bworoshye n'igiciro gito ugereranije n'insinga.
Ishusho ikurikira igaragaza ibice bigize urusobe rw'amafoto rworoshye:laser, igikoresho cyo kongera gukoresha optique no gukuramo ibintu byinshi mu buryo bwa "demultiplexing",icyuma gipima fotonamodulator.

Imiterere y'ibanze ya sisitemu y'itumanaho ya fibre optique igizwe na: transmitter y'amashanyarazi, transmitter y'amajwi, fibre yohereza ubutumwa, receiver y'amajwi n'receiver y'amashanyarazi.
Ibimenyetso by'amashanyarazi byihuta cyane bishyirwa mu buryo bwa "transmitter" hakoreshejwe "transmitter" ijya kuri "transmitter", bigahindurwamo ibimenyetso by'amashanyarazi hakoreshejwe "electro-optical" nka "Laser device" (LD), hanyuma bigahuzwa na "transmission fibre".
Nyuma yo kohereza ikimenyetso cy’urumuri mu ntera ndende binyuze muri fibre imwe, amplifier ya fibre ifite erbium ishobora gukoreshwa mu kongera ikimenyetso cy’urumuri no gukomeza kohereza. Nyuma yo kwakira urumuri, ikimenyetso cy’urumuri gihindurwamo ikimenyetso cy’amashanyarazi na PD n’ibindi bikoresho, maze ikimenyetso cyakirwa n’icyuma gitanga amashanyarazi binyuze mu gutunganya amashanyarazi nyuma. Uburyo bwo kohereza no kwakira ibimenyetso mu cyerekezo gitandukanye ni bumwe.
Kugira ngo ibikoresho bigerweho mu buryo busanzwe, umuyoboro w’amashanyarazi n’umukiriya w’amashanyarazi biri ahantu hamwe bishyirwa buhoro buhoro muri Transceiver y’amashanyarazi.
Umuvuduko wo hejuruModuli ya transceiver y'urumuriigizwe na Receiver Optical Subassembly (ROSA; Transmitter Optical Subassembly (TOSA) ihagarariwe n'ibikoresho bikora, ibikoresho bidakora, imiyoboro ikora n'ibice bigize ikoranabuhanga bifatanye. ROSA na TOSA bipakiye hakoreshejwe laser, fotodetectors, nibindi mu buryo bwa chips optical.

Mu gihe cy’imbogamizi zifatika n’ibibazo bya tekiniki byagaragaye mu iterambere ry’ikoranabuhanga rya microelectronics, abantu batangiye gukoresha fotoni nk’abatwara amakuru kugira ngo bagere ku muvuduko mwinshi, umuvuduko mwinshi, ikoreshwa ry’ingufu nke, no kugabanya umuvuduko wa fotonike inteated circuit (PIC). Intego y’ingenzi ya fotonike interated loop ni ugushyira hamwe imikorere yo gutanga urumuri, guhuza, guhinduranya, kuyungurura, kohereza, kumenya n’ibindi. Imbaraga za mbere zikoreshwa na fotonike interated circuits ziva mu itumanaho ry’amakuru, hanyuma byatejwe imbere cyane muri microwave fotonike, gutunganya amakuru ya quantum, optique idakoresha umurongo umwe, sensor, lidar n’ahandi.
