I-EO Modsutor Serichung: I-Cyclic Fiber Loops kwiTekhnoloji yeLall

Yintoni i-fiber fiber fiber "? Uyazi malini ngayo?

Ingcaciso: I-fible ye-fible ye-fiber apho ukukhanya kungajikeleza amaxesha amaninzi

I-fible ye-fibec fir yiIsixhobo seFiber Opticapho ukukhanya kungajikeleza emva kwexesha. Isetyenziswa ikakhulu kwiNkqubo yokuNikezelela iFinof yeFinocal. Nokuba ubude beI-fiber offical. Oku kunceda ukufundisisa iziphumo eziyingozi kunye nohlalulo oluchaphazela umgangatho wokukhanya womqondiso.

Kwitekhnoloji yase-laser, i-cyclic fiber lops ingasetyenziselwa ukulinganisa i-ai-laser, ngakumbi xa umgca omncinci kakhulu (<1khz). Olu lokongezwa kwendlela yokulinganisa yokuzilinganisa, engafuni ireferensi eyongezelelweyo yase-Gars ukufumana isibonakaliso esivela kwisona, nto leyo ifuna ukusetyenziswa kweentsinga zemody enye. Ingxaki ngetekhnoloji yokuhlola eyakha

Umzobo 1: Umzobo we-schematic we-ringlic fible fir.

Isizathu esisisiseko sokusebenzisa i-fiber lops yi-fiber ubude obuphakathi inokubonelela ngokulibaziseka okude kuba ukukhanya kuhamba uninzi kwifibre. Ukwenzela ukwahlula ukukhanya kweelogo ezahlukeneyo, i-acook-optic modulator inokusetyenziswa kwi-lop ukuvelisa utshintsho oluthile (umzekelo, i-100mhz). Ngenxa yokuba le tshintsho likhulu likhulu kakhulu kunobuqili bomgca, ukukhanya okuhambe nenani elahlukileyo lokujika kwi-loop kunokwahlulwa kwi-domain ye-frequenc. Kwiifoto, eyantlandloloukukhanya kwe-laserkunye nokubetha kokukhanya emva kokutshintsha kobuso kunokusetyenziselwa ukulinganisa ububanzi bomgca.

Ukuba akukho sixhobo sokwenza i-loop, ilahleko kwi-ACoOSO-OKOTO-OKIC Imodyuli kunye nefibre inkulu kakhulu, kwaye ukukhanya kwengqondo kuya kusola kakhulu emva kweelogo ezininzi. Oku kubekwa umda kakhulu inani leelops xa i-widwidth ilinganiswa. I-Ampheber Amplifiisis inokongezwa kwi-loop ukuze isuse lo mda.

Nangona kunjalo, oku kudala ingxaki entsha: Nangona ukukhanya kudlula ngeendlela ezahlukeneyo ukujika kuyahluka ngokupheleleyo, uphawu lokubetha luvela kwizibini ezahlukeneyo zeefoto, ezitshintsha i-spectrum ye-REAT. I-fiber fiber i-fiber inokuthi yenziwe ngokufanelekileyo ukuba ithintele ngempumelelo kwezi ziphumo. Okokugqibela, ubuntununtunu be-fiber ye-fibec ye-fibeli inqunyelwe ngumsindo weI-fiber amplifier. Kuyimfuneko ukuqwalasela ukungabinamali yefayibha kunye nemigca engeyiyo i-loresz kwimpembelelo yedatha
