Ngenxa yobubanzi be-bandwidth obuphezulu kanye nokuncipha okuphansi okulethwa yi-optical fiber, ijubane lenethiwekhi lithatha igxathu elikhulu. Ubuchwepheshe be-fiber optic transceiver bushintsha ngokushesha ukuze kuhlangatshezwane nezidingo ezikhulayo zesivinini kanye nomthamo. Ake sibheke ukuthi lokhu kuthuthuka kuzothinta kanjani izikhungo zedatha.
I-fiberi-transceiver ye-opticiyisekethe ehlanganisiwe (i-IC) engathumela futhi yamukele idatha ngokuzimela kuzo zombili izinhlangothi. Idivayisi ihlanganisa i-transmitter kanye ne-receiver ibe yimojula eyodwa eguqula izimpawu zikagesi zibe izimpawu ezibonakalayo, okwenza lezi zibonakaliso zidluliselwe kahle kusuka kuseva kuya kuseva ngezintambo ze-fiber optic.
I abaguquli bomthumeliukufakwa kukagesi kokukhiphayo okubonakalayo okuvela ku-laser diode noma umthombo wokukhanya we-LED (ukukhanya kuhlanganiswa kube yi-fiber optical ngesixhumanisi bese kudluliswa ngekhebula le-fiber optic). Ukukhanya okuvela ekugcineni kwe-fiber kuhlanganiswa ne-receiver, bese i-detector iguqula ukukhanya kube isignali kagesi, elungiselelwe ukusetshenziswa yidivayisi eyamukelayo. Yini engaphakathi kwe-transceiver ye-fiber optic?
Ama-transceiver e-optical fiber aqukethe ama-transmitter, ama-receiver, amadivayisi e-optical nama-chip. I-chip ivame ukubhekwa njengenhliziyo ye-module ye-fiber optic. Eminyakeni yamuva nje, kube nesithakazelo esikhulayo ekusebenziseni ama-silicon photonics kuma-transceiver chips - ukwakha ama-laser ku-silicon bese kuhlanganiswa izingxenye ze-optical nama-circuits ahlanganisiwe e-silicon. Ibhekana nesidingo sokuxhumeka okusheshayo kusuka ku-rack kuya ku-rack nakuzo zonke izikhungo zedatha. Kwenza inqubo yokuhlanganisa ibe lula ngempumelelo. Ngaphezu kwalokho, ama-transceiver angenziwa abe mancane kakhulu, anciphise indawo yonke yeseva futhi avumele izikhungo zedatha ezincane, ezithambile ngenkathi kugcinwa ubuningi be-port ephezulu. Ngakolunye uhlangothi, usayizi omncane usho ukusetshenziswa kwamandla okuncane kanye nezindleko eziphansi.
Umlando Omfushane Wezithumeli Zokukhanya
Ukwamukelwa kobuchwepheshe be-silicon photonics kuma-transceiver chips kuyisibonelo sentuthuko enkulu kubuchwepheshe be-transceiver ye-fiber-optic. Umkhuba uwukuthi ama-transceiver e-fiber optic aqhubekela phambili ngobukhulu obuncane kanye namazinga aphezulu edatha ukuze abhekane nokwanda kwethrafikhi yedatha ebangelwe yinguquko ye-inthanethi.
