Ngokubanzi, i-transceiver sisixhobo esinokuthumela nokufumana imiqondiso, ngelixa i-transponder iyinxalenye apho iprosesa yayo icwangciselwe ukujonga imiqondiso engenayo kwaye ibe neempendulo ezicwangcisiweyo kwangaphambili kwiinethiwekhi zonxibelelwano ze-fiber-optic. Enyanisweni, ii-transponders zihlala zibonakaliswa yisantya sedatha yazo kunye nomgama ophezulu onokuhanjwa yisignali. Ii-Transceivers kunye nee-transponders zahlukile kwaye azitshintshi. Eli nqaku lichaza umahluko phakathi kwee-transceivers kunye nee-repeaters.
IiTransceivers vs. IiTransponders: Iinkcazo
Kwi-fiber optic communications, ii-transceivers ze-optical zenzelwe ukudlulisa nokufumana imiqondiso ye-optical. Iimodyuli ze-transceiver ezisetyenziswa rhoqo zizixhobo ze-I/O (input/output) ezitshintshwayo ezishushu, ezifakwe kwizixhobo zenethiwekhi, ezifana nokutshintsha kwenethiwekhi, iiseva, nezinye ezinjalo. Ii-transceivers ze-optical zisetyenziswa rhoqo kumaziko edatha, kwiinethiwekhi zeshishini, kwi-cloud computing, kwiinkqubo zenethiwekhi ze-FTTX. Kukho iintlobo ezininzi zee-transceivers, kubandakanya i-1G SFP, i-10G SFP+, i-25G SFP28, i-40G QSFP+, i-100G QSFP28, i-200G kwane-400G transceivers. Zingasetyenziswa neentambo ezahlukeneyo okanye iintambo zobhedu zokudlulisa umgama omde kwiinethiwekhi ezimfutshane okanye ezinde. Ukongeza, kukho ii-transceivers ze-fiber optic ze-BiDi ezivumela iimodyuli ukuba zidlulise kwaye zithole idatha ngefayibha enye ukuze kube lula iinkqubo ze-cabling, ukwandisa umthamo wenethiwekhi, kunye nokunciphisa iindleko. Ukongeza, iimodyuli ze-CWDM kunye ne-DWDM ezidibanisa ubude obahlukeneyo be-wavelengths kwifayibha enye zifanelekile ukudlulisa umgama omde kwiinethiwekhi ze-WDM/OTN.
Umahluko phakathi kweTransceiver kunye neTransponder
Zombini ii-repeaters kunye nee-transceivers zizixhobo ezifanayo ngokusebenzayo eziguqula imiqondiso yombane epheleleyo ye-duplex ibe yimiqondiso ye-optical epheleleyo ye-duplex. Umahluko phakathi kwazo kukuba i-transceiver ye-optical fiber isebenzisa i-serial interface, enokuthumela nokufumana imiqondiso kwimodyuli enye, ngelixa i-repeater isebenzisa i-interface ehambelanayo, efuna iimodyuli ezimbini ze-optical fiber ukuze ifezekise uthumelo lonke. Oko kukuthi, i-repeater kufuneka ithumele isignali ngemodyuli kwelinye icala, kwaye imodyuli kwelinye icala isabela kuloo signal.
Nangona i-transponder inokusingatha ngokulula imiqondiso ehambelanayo enesantya esiphantsi, inobukhulu obukhulu kunye nokusetyenziswa kwamandla okuphezulu kune-transceiver. Ukongeza, iimodyuli ze-optical zinokubonelela kuphela ngokuguqulwa kombane ukuya kwi-optical, ngelixa ii-transponder zinokufikelela kuguquko lombane ukuya kwi-optical ukusuka kwelinye ubude ukuya kwelinye. Ke ngoko, ii-transponder zinokuthathwa njengee-transceiver ezimbini ezibekwe ngasemva, ezinokuthi zisetyenziswe kuthumelo olude kwiinkqubo ze-WDM ezingenakufikelela kuzo zii-transceiver eziqhelekileyo ze-optical.
Ukuqukumbela, ii-transceivers kunye nee-transponders zahlukile ngokwemvelo kumsebenzi kunye nokusetyenziswa. Ii-fibre repeaters zingasetyenziselwa ukuguqula iintlobo ezahlukeneyo zemiqondiso, kuquka i-multimode ukuya kwi-single mode, i-dual fiber ukuya kwi-single fiber, kunye ne-wavelength enye ukuya kwenye i-wavelength. Ii-Transceivers, ezinokuguqula kuphela imiqondiso yombane ibe yi-optical signals, bezisetyenziswa ixesha elide kwiiseva, kwiiswitshi zenethiwekhi yeshishini, nakwiinethiwekhi zeziko ledatha.
