Ezihamba Optical: eziluncedo ngaphezu nobubi

Ngeminyaka, waba nendlela kakhulu ukuze kubekho isibane ubusuku lokulala, eyenziwa koseko hemispherical kwaye aphumele kuyo waveguides msebe. Kwesi sakhiwo ukukhanya ebumnyameni norhatyazo yemisebe ngohlobo amachaphaza amancinci, uvutha kwi imicu kwincam obhityileyo iyakhanya. Oku ngokwenene into intle wenziwa iimveliso inkunkuma ye uhlobo olutsha zokunika ingcaciso. Igama kubo - optic (aka - Umfaki, okt imigca unxibelelwano fibre-optic).

Abazo isimiso ukusebenza

Nawuphi na umqhubi lombane siyakwazi ukumelana kuphela esebenzayo, kodwa izidubuli (capacitive kunye ezenza). Ezi iparameters ebonakalayo zixhomekeke ububanzi we wire, iimpawu zayo yomtshangatshangiso, yaye ke ubude umgca osuka uphawu lomthumeli kunye kwisixhobo eso siwamkelayo umyalezo. Ingakumbi sensitive ukuba resistive channel ophezulu amajelo onxibelelwano esemgangathweni. Ifayibha-optic cable akanayo le ethile, oko ilahleko zincinane kunezo ababhexeshi eqhelekileyo, kuba umdlali ophethe inkcazelo ukukhanya. isenzo channel siseko icacile kwaye ilula. Xa uphawu link na igalelo, aguqulwa ukusuka yombane ukuya optical. Ngamashishini kukho demodulation wayo, kwaye ungena isixhobo receiver-lwazi uye pulses ombane ngokwesiqhelo.

Izinto eziluncedo ze Fiber Channel

Ukongezelela ukuxhathisa wokuphazamiseka yaye eziphango, iintambo ezamehlo nezinye iingenelo ezibalulekileyo kakhulu. Xa ukudluliselwa kolwazi malunga imiphantsi ifayibha lula kakhulu ukuba kugcinwe kuyimfihlo, ngokuba cishe akunakwenzeka ukudibanisa kubo ngasese. Enye inzuzo yale ndlela ukudluliswa kwezoqoqosho. Copper - i zentsimbi zexabiso kunye nombala, kwi izinto waveguide ixabiso ifikeleleke ngakumbi. Intambo kokugcina yenziwa zwi okanye nokwenziwa Polymer ekhethekileyo (fluoro-aluminate, okanye fluoro-zirconate), nto leyo nayo (isidima wesithathu) Ikhaphukhaphu kunoko iingcingo sisinyithi kufuneka bahlolwe.

ukushiyeka zonxibelelwano optical

Ewe, iintambo enombala, ngokunjalo yonke into kweli hlabathi, ayikho ngaphandle kuneengxaki.

Okokuqala, ukubuyisela unxibelelwano beesekethe evulekileyo lufuna ukutshintshwa kwindawo yonke yonakele, akanako spliced waveguides ngaloo isandisa iindleko zokusilungisa.

Okwesibini, umsebenzi wofakelo kwakhona ngemali cheap. Kuba kokuziphumeza kufuneka ngqo oomatshini, kwaye kuyabiza. Nezakhono eziyimfuneko kakhulu, kwaye ke kufuneka uhlawule ngokufanelekileyo.

Okwesithathu, ukuba uthe umqondiso Converter kwi igalelo nemveliso imigca, kwakunye izihlanganisi (izixhobo ezinika utshintshe nje), amabango phezulu kakhulu kwi ukuthembeka, iilahleko ezamehlo okuchaneka. Ukuba umgangatho nto ibiza imali, akukho mntu kufuneka ukucacisa.

Communication elizayo

Sekunjalo, ezilungileyo ngakumbi. ezihamba Optical angadlulisela uphawu broadband, nto leyo eyandisa kakhulu isantya ulwazi lonaniso (kulinganiswa kakade terabits yesibini nganye). Xa olu eziphango incinane kakhulu (xa kukho ngamaza 1,55 microns, kuba dB 0,22 kuphela / km). Ngaphezu koko, isakhono amaza okukhanya lihamba ephambana (kunye nokwehlukana ezahlukeneyo) nganye umqhubi fibre optic kwandisa amathuba. zoPhuculo zazo, kuyaqhubeka.
