Fiber optic transceiver ndi chipangizo chomwe chimagwiritsidwa ntchito potumiza ma siginecha a kuwala mu fiber optic communication. Amakhala ndi emitter yowala (light emitting diode kapena laser) ndi cholandila kuwala (chowunikira kuwala), chomwe chimagwiritsidwa ntchito kutembenuza ma siginecha amagetsi kukhala ma siginecha owoneka ndikuwatembenuza.
Ma fiber optic transceivers amagwira ntchito ngati mlatho pakati pa ma siginecha owoneka ndi magetsi mumayendedwe olumikizirana a fiber optic, kukwaniritsa kutumizirana mwachangu komanso kokhazikika kwa data. Itha kugwiritsidwa ntchito pamanetiweki amderali (LANs), ma network amdera lalikulu (WANs), ma data center interconnections, mawayilesi olumikizirana opanda zingwe, ma sensor network, ndi zochitika zina zotumizira mwachangu.
Mfundo yogwirira ntchito:
Optical transmitter: Chizindikiro chamagetsi chikalandiridwa, gwero la kuwala (monga laser kapena LED) mu transmitter ya kuwala imatsegulidwa, ndikupanga chizindikiro cha kuwala chogwirizana ndi chizindikiro cha magetsi. Zizindikiro za kuwala izi zimafalitsidwa kudzera mu ulusi wa kuwala, ndipo mafupipafupi awo ndi njira yosinthira zimatsimikizira kuchuluka kwa deta ndi mtundu wa ma protocol.
Optical receiver: Wolandila kuwala ali ndi udindo wotembenuza ma siginecha owoneka kukhala ma siginecha amagetsi. Nthawi zambiri amagwiritsa ntchito photodetectors (monga photodiodes kapena photoconductive diode), ndipo pamene chizindikiro cha kuwala chikulowa mu chowunikira, mphamvu ya kuwala imasinthidwa kukhala chizindikiro chamagetsi. Wolandira amatsitsa chizindikiro cha kuwala ndikuchisintha kukhala chizindikiro choyambirira chamagetsi.
Zigawo zazikulu:
● Optical transmitter (Tx): yomwe ili ndi udindo wotembenuza zizindikiro zamagetsi kukhala zizindikiro za kuwala ndi kutumiza deta kudzera muzitsulo za optical.
● Optical Receiver (Rx): Amalandira zizindikiro za kuwala kumapeto kwina kwa fiber ndi kuwatembenuza kukhala zizindikiro zamagetsi kuti apangidwe ndi chipangizo cholandira.
● Optical connector: amagwiritsidwa ntchito kugwirizanitsa ma transceivers a fiber optic ndi optical fibers, kuonetsetsa kuti kufalikira kwabwino kwa zizindikiro za kuwala.
● Control circuit: amagwiritsidwa ntchito poyang'anira mawonekedwe a optical transmitter ndi wolandila, ndi kupanga kusintha kofunikira kwa magetsi a magetsi.
Ma fiber optic transceivers amasiyana malinga ndi kuchuluka kwawo, kutalika kwa mawonekedwe, mawonekedwe, ndi zina. Mitundu yodziwika bwino ya mawonekedwe imaphatikizapo SFP, SFP+, QSFP, QSFP+, CFP, ndi zina zotero. Mtundu uliwonse wa mawonekedwe uli ndi zochitika zapadera zogwiritsira ntchito ndi kuchuluka kwa ntchito. Ma fiber optic transceivers amagwiritsidwa ntchito kwambiri m'magawo amakono olankhulirana, kupereka chithandizo chofunikira chaukadaulo pamayendedwe othamanga kwambiri, mtunda wautali, komanso kutsika kochepa kwa fiber optic.
