3.IFayibha Optic Attenuator

I-China fiber fiber optic umzi-mveliso

1. Kutheni ufuna i-fiber offic abambelele

Ukuba usokola ngokukhanya okukhulu kakhulu i-fiber optic, I-fiber optic abavelitor yenye yokunciphisa inqanaba lamandla lophawu lokukhanya. Ngokusebenzisa amaNqaku abahamba ngenyawo, Unokufikelela kwiyona ndlela ilungileyo ye-fiber optic.

Nje, Kukho iimeko ezimbini apho unokufuna i-fiber optic attenuators kwinkqubo yakho.

Xa kufuneka unciphise amandla afumanekileyo.

Ngamanye amaxesha umqondiso ufikelwe ngumamkeli womelele kakhulu kwaye unokukhulula izinto ezivumayo. Oku kunokubangelwa kukungqubana phakathi kwabatshintshi kunye nabamkeli okanye ukusetyenziswa kwabaguquli beendaba zenzelwe ixesha elide. Kule meko, Ungafaka ama-Antengelican Attenuashit kwikhonkco le-fiber optic ukunciphisa amandla eSigineli kwaye angqinelane kakuhle kwinqanaba lomqondiso.

Apho unokufuna ama-Antetigaashini xa uvavanya amabanga aphantsi.

Ngexesha lovavanyo, Abangathathi okwethutyana kwinkqubo yokongeza isixa sexesha lokulahleka kophawu kunye nenqanaba lamandla ovavanyo kwi-fiber optic inkqubo. Nge-Transmitter ivuliwe kwaye isebenzisa imitha yamandla e-fiber optic yeseti yenkqubo yokusebenza, Ungasebenzisa umbukeli ukuba avavanye amandla enkqubo.

2. Iindidi ze-fiber atterator fibconet ziya kubonelela

I-fiber optic ayisebenzi ingena ngeendlela ezininzi ezahlukeneyo. Kwintengiso, Ungazifumana iintlobo ezahlukeneyo zentengo ye-attenuat ehlelwe ngohlobo lwesinxibelelanisi, Uhlobo lwentambo kunye nangaphezulu.

Ngokubanzi, badityaniswe ngokwamaqela abathile abaphantsi (I-foa) kunye ne-attelicapes eyahlukileyo (Voa). Ungawahlulahlula kwimoni enye kunye ne-Atti-Attinators Antetinapt esekwe kwiindidi zentambo.

Umnxibelelanisi we-official off

Njengoko igama libonisa, I-Anteloators emiselweyo yenzelwe ukuba ibe nenqanaba elingaguqukiyo lokuthathwa kwe-faprical fiber, Ngokwesiqhelo phakathi kwe-1DB kunye ne-30DB. Abasebenzi abakhethiweyo abakhethiweyo bahlala besebenzisa nayiphi na imicu, Iifliki ezibonakalayo, okanye igunya lilonke, Ngelixa abantu abangakhethwanga bahlala besebenzisa ilahleko ye-GAP okanye imigaqo yokubonisa.

Zimbini iintlobo zexabiso elisigxina: Uhlobo lomgca Uphuculo olongezelelweyo kumgangatho wokuqala we-APON - kunye nokuwa kancinci kancinci kwi-ATM njengeprothokholi - kukhokelele ngokupheleleyo. Uhlobo lomnxibelelanisi. Uhlobo lomgca lubukeka njengentambo ye-fiber ye-fiber, Ngelixa umnxibelelanisi we-anteturetor ujongeka ngathi ngumnxibelelanisi we-bulkhead fiber. Aba bangatshatanga banokusetyenziswa kwiinethiwekhi zonxibelelwano, Izixhobo zovavanyo lweFipber, Uthungelwano lweNdawo yeNgingqi (I-LAN) kunye neenkqubo zekati.

I-Optical Staricator eyahlukileyo

Abathengi abaguqulweyo, okanye abaguquli abaguqukayo (Voa), Sebenzisa isihluzi esiguqukayo sokungathathi cala. Basetyenziswa ngokubanzi ukuze kuvavanywe kwaye kulinganiselwe, Kodwa bamkela ngokubanzi kwi-erbium ye-eriber amplifier (EDFA) Ukulinganisa amandla okukhanya phakathi kweendlela ezahlukeneyo.

Zimbini iintlobo ze-Attelications eziguquguqukayo: I-Antetionators eyahlukileyo kunye ne-Antetiators eqhubekayo.

I-Attenuators eyahlukileyo inokuthintela i-antition yokwahlulahlulahlula amanyathelo awaziwayo njenge-0.1db, 0.5dB, okanye i-1db.

I-Atticali eQhelekileyo engafaniyo inokubonelela ngenqanaba elichanekileyo lokuthambisa ngolungelelwaniso oluguqukayo.

Oku kuvumela abaqhubi ukuba bahlengahlengise umkhweli ngokukhawuleza kwaye ngokuchanekileyo ngaphandle kokuphazamiseka kwisekethe.
