Kodi ntchito ya ma transceivers a fiber optic ndi yotani?

Ma transceiver a kuwala nthawi zambiri amagwiritsidwa ntchito m'malo ogwirira ntchito pa netiweki komwe zingwe za Ethernet sizingaphimbe ndipo ulusi wa kuwala uyenera kugwiritsidwa ntchito kukulitsa mtunda wotumizira mauthenga, ndipo amachitanso gawo lalikulu pothandiza kulumikiza mtunda womaliza wa ulusi wa kuwala ku netiweki ya m'dera la mzinda ndi zina zotero. Ndi ma transceiver a fiber optic, imaperekanso yankho lotsika mtengo kwa ogwiritsa ntchito omwe amafunika kukweza makina awo kuchokera ku mkuwa kupita ku ulusi, kwa iwo omwe alibe ndalama, anthu ogwira ntchito kapena nthawi. Ntchito ya transceiver ya fiber optic ndikusintha chizindikiro chamagetsi chomwe tikufuna kutumiza kukhala chizindikiro cha kuwala ndikuchitumiza. Nthawi yomweyo, imatha kusintha chizindikiro cha kuwala cholandiridwa kukhala chizindikiro chamagetsi ndikuchiyika kumalo athu olandirira.

Ndi ma transceiver a fiber optic, imaperekanso yankho lotsika mtengo kwa ogwiritsa ntchito omwe akufunika kukweza makina awo kuchokera ku mkuwa kupita ku ulusi, koma alibe ndalama, mphamvu kapena nthawi. Pofuna kuonetsetsa kuti zikugwirizana mokwanira ndi makadi a netiweki a opanga ena, ma repeater, ma hubs ndi ma switch ndi zida zina za netiweki, zinthu za fiber optic transceiver ziyenera kutsatira mosamalitsa muyezo wa intaneti wa 10Base-T, 100Base-TX, 100Base-FX, IEEE802.3 ndi IEEE802.3u. Kuphatikiza apo, ziyenera kutsatira FCC Part15 pankhani ya chitetezo cha EMC ku radiation yamagetsi. Masiku ano, pamene ogwira ntchito akuluakulu akunyumba akumanga mwamphamvu ma netiweki ammudzi, ma netiweki akusukulu ndi ma netiweki amabizinesi, kugwiritsa ntchito zinthu za optical fiber transceiver kukuwonjezekanso kuti zikwaniritse zosowa za zomangamanga za netiweki.

Chosinthira kuwala kwa ulusi (chomwe chimadziwikanso kuti chosinthira kuwala kwa kuwala) ndi chipangizo cha netiweki chomwe chimasintha zizindikiro zamagetsi ndi zizindikiro za kuwala kukhala zina. Ndi chosinthira kuwala chosavuta. Ntchito za chosinthira kuwala kwa ulusi wa kuwala pa gawo lakuthupi zimaphatikizapo: kupereka mawonekedwe olowera amagetsi a RJ45, kupereka mawonekedwe otulutsira chizindikiro cha ulusi wa SC kapena ST; kuzindikira kusintha kwa "magetsi-optical, optical-electrical" kwa zizindikiro; kuzindikira ma code osiyanasiyana pa gawo lakuthupi.
