Kusanthula mozama kwa ma transceivers a fiber optic

Chifukwa cha kuchuluka kwa bandwidth komanso kuchepa kwa mphamvu ya fiber optical, liwiro la netiweki likukwera kwambiri. Ukadaulo wa fiber optic transceiver ukusinthanso mwachangu kuti ukwaniritse zosowa zomwe zikuchulukirachulukira za liwiro ndi mphamvu. Tiyeni tiwone momwe kupita patsogolo kumeneku kudzakhudzira malo osungira deta.

Ulusichosinthira kuwala kwa masondi dera lolumikizidwa (IC) lomwe limatha kutumiza ndikulandira deta payokha mbali zonse ziwiri. Chipangizochi chimaphatikiza chotumizira ndi cholandirira kukhala gawo limodzi lomwe limasintha ma siginecha amagetsi kukhala ma siginecha a kuwala, zomwe zimathandiza kuti ma siginecha awa azitha kutumizidwa bwino kuchokera ku seva kupita ku seva kudzera pa zingwe za fiber optic.

The otembenuza ma transmitterKulowetsa kwamagetsi mu kuwala kotulutsa kuchokera ku laser diode kapena gwero la kuwala kwa LED (kuwala kumalumikizidwa kukhala ulusi wowala kudzera pa cholumikizira ndikutumizidwa kudzera mu chingwe cha fiber optic). Kuwala kochokera kumapeto kwa ulusi kumalumikizidwa ku cholandirira, ndipo chowunikira chimasintha kuwala kukhala chizindikiro chamagetsi, chomwe chimakonzedwa kuti chigwiritsidwe ntchito ndi chipangizo cholandirira. Kodi mkati mwa chosinthira cha fiber optic muli chiyani?

Ma transceiver a fiber optical amakhala ndi ma transmitter, ma receiver, zida zowunikira ndi ma chips. Chip nthawi zambiri imaonedwa ngati mtima wa fiber optic module. M'zaka zaposachedwa, pakhala chidwi chowonjezeka chogwiritsa ntchito silicon photonics mu ma transceiver chips - kupanga ma laser pa silicon kenako kuphatikiza zigawo zowunikira ndi ma silicon integrated circuits. Zimathandiza kufunikira kwa kulumikizana mwachangu kuchokera pa raki kupita ku raki komanso kudutsa malo osungira deta. Zimathandiza kuti njira yosonkhanitsira ikhale yosavuta. Kuphatikiza apo, ma transceiver amatha kukhala ang'onoang'ono, kuchepetsa kuchuluka kwa seva yonse ndikulola malo osungira deta ang'onoang'ono komanso osalimba pamene akusunga kuchuluka kwa ma port. Kumbali ina, kukula kochepa kumatanthauza kugwiritsa ntchito mphamvu zochepa komanso mtengo wotsika.

Mbiri Yachidule ya Optical Transceivers
Kugwiritsa ntchito ukadaulo wa silicon photonics mu ma transceiver chips ndi umboni wina wa kupita patsogolo kwakukulu mu ukadaulo wa fiber-optic transceiver. Chizolowezichi ndichakuti ma fiber optic transceiver akupita patsogolo kwambiri komanso kuchuluka kwa deta kuti athe kuthana ndi kuchuluka kwa kuchuluka kwa deta komwe kwabwera chifukwa cha kusintha kwa intaneti.
