Transceiver ya analogi ndi mtundu wa transceiver ya kuwala, yomwe imagwiritsa ntchito kusintha kwafupipafupi kwa analogi, kusinthasintha kwa matalikidwe, ndi kusintha kwa gawo kuti musinthe mavidiyo a baseband, audio, deta ndi zizindikiro zina pamtundu wina wonyamulira, ndikuzitumiza kupyolera mu transceiver optical transceiver. .Kutumiza chizindikiro cha kuwala: Chizindikiro cha kuwala chomwe chimatulutsidwa ndi analogi optical transceiver ndi chizindikiro cha analog optical modulation, chomwe chimasintha matalikidwe, mafupipafupi, ndi gawo la chizindikiro cha kuwala ndi matalikidwe, mafupipafupi, ndi gawo la chizindikiro chonyamulira cha analogi.Ndiye, transceiver ya analoji ya kuwala ndi chiyani?Kodi ubwino ndi kuipa kwa ma analogi optical transceivers ndi chiyani?Chonde tsatiraniChithunzi cha JHA TECHkuphunzira za analogi kuwala transceiver.
Transceiver ya analog Optical imagwiritsa ntchito ukadaulo wosinthira wa PFM kutumiza ma siginecha munthawi yeniyeni.Mapeto otumizira amapanga kusintha kwa PFM pa kanema wa analogi, kenako kutembenuza magetsi.Chizindikiro cha kuwala chikatumizidwa kumalo olandirira, imapanga kutembenuka kwa photoelectric, kenako imapanga PFM demodulation kuti ipeze chizindikiro cha kanema.Chifukwa chogwiritsa ntchito ukadaulo wosinthira wa PFM, mtunda wake wotumizira ukhoza kufika 50Km kapena kupitilira apo.Kupyolera mukugwiritsa ntchito teknoloji ya wavelength division multiplexing, njira ziwiri zotumizira zithunzi ndi zizindikiro za deta zingathenso kuzindikirika pamtundu umodzi wa kuwala kuti ukwaniritse zofunikira zenizeni za polojekiti.
Kuipa kwa ma analogi optical transceiver:
a) Kukonza zolakwika pakupanga kumakhala kovuta;
b) Ndizovuta kuti chingwe chimodzi cha kuwala chizindikire kufalikira kwa zithunzi zamakanema ambiri, ndipo magwiridwe ake achepetsedwa.Ma transceiver amtundu wa analogi amatha kungotumiza ma tchanelo a 4 a zithunzi pamtundu umodzi wa kuwala;
c) Kulephera koletsa kusokoneza, komwe kumakhudzidwa kwambiri ndi chilengedwe, komanso kutentha kwanyengo;
d) Chifukwa kusinthika kwa analogi ndi ukadaulo wotsitsa kumatengera, kukhazikika kwake sikokwanira.Pamene nthawi yogwiritsira ntchito ikuwonjezeka kapena maonekedwe a chilengedwe akusintha, ntchito ya transceiver ya kuwala idzasinthanso, zomwe zidzabweretsa zovuta pakugwiritsa ntchito uinjiniya.
