Chithunzi cha CWDM
Mafotokozedwe Akatundu
CWDM-55 ndi chipangizo cha 1550nm CWDM mux kapena demux chokhala ndi fyuluta yomangidwira 1550nm yomwe imawonjezera chizindikiro cha 1550nm pa doko la com kapena kugwetsa chizindikiro cha 1550nm kuchokera pa doko la com. Chipangizo chamndandanda wa CWDM-xx ndichabwino kuwonjezera kapena kutsitsa njira ya xx CWDM ku fiber optic system. Kutalika kwa mawonekedwe a CWDM kuchokera ku 1270nm, 1290nm, 1310nm, 1330nm, 1330nm, 1350nm, 1370nm, 1390nm, 1410nm, 1430nm, 1014nm, 1450nm, 1450nm 1530nm, 1550nm, 1570nm, 1590nm mpaka 1610nm, pomwe 1310nm ndi 1490nm ndi GPON njira ziwiri zowonera mafunde a fiber kunyumba, 1550nm ndiye mawonekedwe owulutsira omwe amawulutsidwa pogwiritsa ntchito makina amplifier optical fiber. Chida chokhazikika cha Nch CWDM mux kapena de-mux ndikuyika zida za N-1 zotulutsa CWDM zosefera imodzi.
Kulumikizana kwa Fiber optic kwasintha dziko lino kuyambira 1980s. Single mode fiber ili ndi ubwino wokonza mosavuta, kutsika pang'ono, kutalika kwa mawonekedwe a mawonekedwe a mawonekedwe ndi deta yothamanga pamtundu uliwonse wa kuwala. Kuphatikiza apo, CHIKWANGWANI chimakhala chokhazikika pakusintha kwa kutentha komanso malo osiyanasiyana. Mauthenga a Fiber optic akugwira ntchito zofunika kwambiri kuyambira pakusinthana zidziwitso kumayiko ena kupita ku zosangalatsa zabanja. Zipangizo za WDM, ma fiber splitters ndi ma fiber patchcords ndizofunikira kwambiri mu passive optical network (PON), zomwe zimathandizira ma multi optical wavelengths omwe amagwira ntchito limodzi kuchokera ku mfundo imodzi kupita kunjira ziwiri. Pamodzi ndi zatsopano zomwe zimagwira ntchito monga laser, photodiode, APD ndi optical amplifier, passive fiber optic particles zimapangitsa chingwe cha fiber kupezeka pakhomo la olembetsa kunyumba pamtengo wotsika mtengo. Intaneti yothamanga kwambiri, kuwulutsa kwakukulu kwamavidiyo a HD pa fiber kumapangitsa dziko lapansi kukhala laling'ono.
Chipangizo cha CWDM chitha kugwiritsidwa ntchito ngati chida choyimirira kapena chophatikizidwa mu laser ndi photodiode. Phukusi lodziwika bwino ndi chubu cha fiber pigtail atatu, bokosi la pulasitiki lamakaseti, nyumba za LGX ndi 19 ”1RU chassis.
