Uthini Umahluko phakathi kwe-UPC kunye ne-APC Connector?

Sidla ngokuva malunga neenkcazo ezifana ne "LC/UPC multimode duplex fiber optic patch cable", okanye "ST/APC single-mode simplex fibre optic jumper".Athetha ntoni la magama UPC kunye APC isinxibelelanisi?Yintoni umahluko phakathi kwabo?Eli nqaku lisenokukunika iingcaciso ezithile.

Iyintoni intsingiselo ye-UPC kunye ne-APC?

Njengoko sisazi, iindibano zentambo yefiber optic ikakhulu zineziqhagamshelo kunye neentambo, ngoko ke igama lendibano yefayibha yentambo inxulumene negama lesinxibelelanisi.Sibiza intambo ye-LC fiber patch cable, kuba le ntambo ine-LC fiber optic connector.Apha amagama athi UPC kunye ne-APC anxulumene kuphela nezihlanganisi zefiber optic kwaye azinanto yakwenza neentambo zefiber optic.

Nanini na xa isinxibelelanisi sifakwe ekupheleni kwefiber, ilahleko iyenzeka.Enye yale lahleko yokukhanya ibonakaliswa ngokuthe ngqo ngasemva kwifayibha ukuya kumthombo wokukhanya okuvelisileyo.Ezi zibonakalisi ngasemva ziya konakalisa imithombo yokukhanya ye-laser kwaye ziphinde ziphazamise isignali edlulisiweyo.Ukunciphisa ukubonakaliswa ngasemva, sinokupholisa i-ferrules yesiqhagamshelo kwimiphetho eyahlukeneyo.Kukho iintlobo ezine zesitayile sokupholisha se-ferrule kuzo zonke.UPC kunye APC ziindidi ezimbini zazo.Phakathi kwe-UPC imele i-Ultra Physical Contact kunye ne-APC imfutshane ye-Angled Physical Contact.

Umahluko phakathi kwe-UPC kunye ne-APC Connector

Umahluko ophambili phakathi kwe-UPC kunye ne-APC isinxibelelanisi bubuso bokuphela kwefiber.Izihlanganisi ze-UPC zikhazimlisiwe ngaphandle kwe-engile, kodwa izihlanganisi ze-APC zinobuso besiphelo sosinga obukhazimliswe kwi-engile ye-8-degree.Ngeziqhagamshelo ze-UPC, nakuphi na ukukhanya okubonakalisiweyo kubonakaliswa ngqo ngasemva ukuya kumthombo wokukhanya.Nangona kunjalo, isiphelo sobuso be-engile yesiqhagamshelo se-APC sibangela ukuba ukukhanya kubonakaliswe kwi-engile kwi-cladding ngokuchasene ngqo nomva ukuya kumthombo.Oku kubangela umahluko othile kwilahleko yembuyekezo.Ke ngoko, isinxibelelanisi se-UPC sidla ngokufuneka sibe nobuncinci -50dB ilahleko yokubuya okanye ngaphezulu, ngelixa ilahleko yokubuyisela isinxibelelanisi se-APC kufuneka ibe -60dB okanye ngaphezulu.Ngokubanzi, okukhona ilahleko yokubuya iphezulu kokukhona ngcono ukusebenza kokudibana kwezihlanganisi ezimbini.Ngaphandle kobuso befiber end, omnye umahluko ocacileyo ngumbala.Ngokubanzi, izihlanganisi ze-UPC ziluhlaza okwesibhakabhaka ngelixa izihlanganisi ze-APC ziluhlaza.

Ukuqwalaselwa kweSicelo se-UPC kunye ne-APC Connectors

Akukho mathandabuzo ukuba ukusebenza optical of APC izihlanganisi ingcono izihlanganisi UPC.Kwimarike yangoku, izixhumi ze-APC zisetyenziswa ngokubanzi kwizicelo ezifana ne-FTTx, i-passive optical network (PON) kunye ne-wavelength-division multiplexing (WDM) evakalelwa ngakumbi ekubuyiseleni ilahleko.Kodwa ngaphandle kokusebenza kwamehlo, iindleko kunye nokulula kufuneka kuthathelwe ingqalelo.Ngoko ke kunzima ukuthetha ukuba isinxibelelanisi esinye sibetha esinye.Enyanisweni, nokuba ukhetha i-UPC okanye i-APC iya kuxhomekeka kwimfuno yakho ethile.Ngezo zicelo zibiza ukuchaneka okuphezulu kwe-fiber optical signaling, i-APC kufuneka ibe yingqwalasela yokuqala, kodwa iinkqubo zedijithali ezincinci ziya kusebenza ngokulinganayo usebenzisa i-UPC.
