Nguwuphi uMahluko: Imowudi enye vs iMultimode Fiber?

Ifiber ebonakalayo yifiber eguquguqukayo, ecacileyo eyenziwe ngeglasi ekhutshiweyo okanye iplastiki, ijiyile kancinci kuneenwele zomntu.Iintsinga zamehlo zisetyenziswa rhoqo njengendlela yokuhambisa ukukhanya phakathi kweziphelo zimbini zefiber kwaye zifumane usetyenziso olubanzi kunxibelelwano lwefiber-optic, apho zivumela ukuhanjiswa kwimigama emide kunye nakwi-bandwidths eziphezulu kuneentambo zocingo.Iintsinga ze-Optical zibandakanya undoqo ocacileyo ongqongwe yinto yokugquma ecacileyo enesalathiso esisezantsi se-refraction.Ukukhanya kugcinwa kwi-core yi-phenomenon ye-reflection yangaphakathi epheleleyo ebangela ukuba i-fiber isebenze njenge-waveguide.Ngokubanzi, kukho iindidi ezimbini zefiber optical: iifiber ezixhasa iindlela ezininzi zokusasaza okanye iindlela ezinqamlezayo zibizwa ngokuba ziifibers zemultimode (MMF), ngelixa ezo zixhasa imowudi enye zibizwa ngokuba ziintsinga zemowudi enye (SMF).Imowudi enye vs ifayibha ezininzi: yintoni umahluko phakathi kwazo?Ukufunda esi sicatshulwa kuya kukunceda ufumane impendulo.

Imowudi eNye vs iMultimode Fiber: Yeyiphi imowudi enye yefiber ebonakalayo?

Kunxibelelwano lwe-fiber-optic, i-fiber optical mode eyodwa (SM) i-fiber optical fiber eyenzelwe ukuthwala ukukhanya kuphela ngokuthe ngqo kwi-fiber - imodi enqamlezayo.Kwimowudi enye ye-fiber optical, kungakhathaliseki ukuba isebenza kwi-100 Mbit / s okanye i-1 Gbit / s amazinga omhla, umgama wokuhambisa unokufikelela ubuncinane kwi-5 km.Ngokuqhelekileyo, isetyenziselwa ukuhanjiswa kwesignali yomgama omde.

Imowudi enye vs iMultimode Fiber: Yintoni i-multimode optical fiber?

I-Multimode optical fiber (MM) luhlobo lwefiber optical esetyenziswa kakhulu kunxibelelwano kwimigama emifutshane, njengangaphakathi kwesakhiwo okanye kwikhampasi.Isantya sothumelo oluqhelekileyo kunye nemida yomgama yi-100 Mbit / s kumgama ukuya kwi-2 km (100BASE-FX), i-1 Gbit / s ukuya kwi-1000m, kunye ne-10 Gbit / s ukuya kwi-550 m.Kukho iindidi ezimbini zezalathisi ze-multimode: isalathisi senyathelo kunye nesalathisi somgangatho.

Yintoni umahluko phakathi kwefiber optical mode kunye nemultimode?

Ukuthotywa: Ukuthotywa kwefiber yemultimode iphezulu kunefiber ye-SM ngenxa yobukhulu bayo obungundoqo.I-fiber core ye-single mode cable imxinwa kakhulu, ngoko ke ukukhanya okudlula kwezi ntambo zefiber optical akubonakali amaxesha amaninzi, nto leyo egcina ukuthomalalisa kubuncinci.

Idayamitha engundoqo:Umahluko ophambili phakathi kwe-multimode kunye ne-fiber yemowudi enye kukuba eyokuqala inedayamitha engundoqo engundoqo, ene-diameter engundoqo eyi-50 okanye i-62.5 µm kunye nedayamitha yokugquma eyi-125 µm.Ngelixa umsinga oqhelekileyo wemowudi unedayamitha engundoqo phakathi kwe-8 kunye ne-10 µm kunye nedayamitha egqunyiweyo ye-125 µm.
