Yuav ua li cas ib tug kho qhov muag transciver ua tiav cov paib kev sib kis?

1. Cov teeb liab hloov dua siab tshiab
Lub cim hluav taws xob tawm tswv yim: kev ua haujlwm ntawm kev kho qhov muag transciver pib nrog tau txais cov cim hluav taws xob los ntawm cov khoom siv hluav taws xob xws li khoos phis tawj, hloov pauv lossis cov routers. Cov teeb liab no feem ntau yog digital cov cim, xws li cov cim Ethernet.
Analog-rau-digital hloov dua siab tshiab: Kev hloov kho kho qhov muag yuav xav hloov cov cim analog (xws li cov cim suab (xws li cov cim digital). Cov txheej txheem no feem ntau ua tiav los ntawm cov kev sib tw ua piv txwv-rau-digital converter (ADC).
Lub cim ntsuas kho qhov muag tau hloov dua tshiab rau hauv lub cim digital, lub davhlau ya nyob twg yuav siv cov cim ntsuas digital rau hauv kev ntsuas digital. Lasers feem ntau yog siv rau kev xa mus ntev vim tias lawv tuaj yeem tsim cov cim muaj zog kho tshiab.
2. Optical Cov Kev Nkag Mus Sib Kis
Kev sib kis tau los ntawm Optical Fibers: cov teeb liab hloov kho qhov muag yog kis tau los ntawm Optical Fibers. Qhov muag tau kho qhov muag tau, raws li cov kis tau kho qhov muag nruab nrab, thiab muaj peev xwm kis tau cov cim kho qhov muag tsis muaj kev cuam tshuam los ntawm cov hluav taws xob hluav taws xob.
Kos npe tawm ua kom nrov: hauv kev sib kis tau ntev, optical cov cim yuav ua rau muaj zog vim muaj kev cuam tshuam. Txhawm rau tswj lub teeb liab lub zog, kho qhov muag hloov kho kho qhov muag, xws li erbium-doped fiber ntau amplififefe (edfa), kom ua kom nrov dua lub teeb liab thaum tsim nyog.
