13. Zidityaniswa njani iintambo zefiber optic?
Iindidi zokuCandwa
Kukho iindlela ezimbini zokudibanisa, oomatshini okanye ukudibanisa.Zombini ezi ndlela zibonelela ngelahleko esezantsi kakhulu yokufaka kuneziqhagamshelo zefiber optic.
I-Mechanical splicing
I-Optical cable mechanical splicing yenye indlela engayifuniyo i-fusion splicer.
I-Mechanical splices yi-splices ye-fibers optical ezimbini okanye ngaphezulu ezilungelelanisa kwaye zibeke amacandelo agcina iifibers zihambelana ngokusebenzisa i-index ehambelana ne-fluid.
I-Mechanical splicing isebenzisa i-mechanical splicing encinci malunga ne-6 cm ubude kunye ne-1 cm ububanzi ukudibanisa ngokusisigxina imicu emibini.Oku kulungelelanisa ngokuchanekileyo iintsinga ezimbini ezingenanto kwaye zikhuseleke ngoomatshini.
Izigqubuthelo eziqholiweyo, izigqubuthelo ezincamathelayo, okanye zombini zisetyenziselwa ukukhusela i-splice ngokusisigxina.
Imicu ayidityaniswanga ngokusisigxina kodwa idityaniswa ukuze ukukhanya kudlule ukusuka kwenye ukuya kwenye.(ilahleko yokufaka <0.5dB)
Ilahleko ye-splice idla ngokuba yi-0.3dB.Kodwa i-fiber mechanical splicing yazisa imbonakalo ephezulu kuneendlela zokudityaniswa kwe-fusion.
I-optical cable splice mechanical splice incinci, kulula ukuyisebenzisa, kwaye ilungele ukulungiswa ngokukhawuleza okanye ukufakwa ngokusisigxina.Zineentlobo ezisisigxina kunye nokungena kwakhona.I-optical cable mechanical splices iyafumaneka kwimowudi enye okanye i-multi-mode fiber.
Ukudibanisa ukudibanisa
I-Fusion splicing ibiza kakhulu kunokudibanisa ngoomatshini kodwa ihlala ixesha elide.Indlela yokudibanisa ukudibanisa idibanisa ii-cores kunye nokunciphisa okuncinci.(ilahleko yokufaka <0.1dB)
Ngexesha lenkqubo yokudibanisa, i-fusion splicer ezinikeleyo isetyenziselwa ukulungelelanisa ngokuchanekileyo iziphelo zefiber ezimbini, emva koko iziphelo zeglasi "zidityaniswe" okanye "zidityaniswe" kunye zisebenzisa i-arc yombane okanye ubushushu.
Oku kudala uxhulumaniso olungafihliyo, olungabonakaliyo, kunye noluqhubekayo phakathi kweefibers, okwenza ukuba ilahleko ephantsi ye-optical transmission.(Ilahleko eqhelekileyo: 0.1 dB)
I-fusion splicer yenza i-optical fiber fusion ngamanyathelo amabini.
1. Ulungelelwaniso oluchanekileyo lwemicu emibini
2. Yenza i-arc encinci yokunyibilikisa iintsinga kwaye uzidibanise
Ukongeza kwilahleko esezantsi ye-splice ye-0.1dB, izibonelelo ze-splice ziquka ukubonakaliswa okumbalwa ngasemva.
