FAAHFAAHINTA Alaabada

Sharaxaada Alaabta

CWDM-55 waa 1550nm CWDM mux ama qalab demux ah oo leh shaandheyn ku dhex jirta 1550nm kaas oo ku daraya signalka 1550nm dekedda com ama ka soo daadiya signalka 1550nm dekedda com. Qalabka taxanaha CWDM-xx ayaa ku habboon in lagu daro ama lagu rido xx CWDM kanaalka nidaamka fiber optic-ga. Mawjada dhererka CWDM ee caadiga ah laga bilaabo 1270nm, 1290nm, 1310nm, 1330nm, 1330nm, 1350nm, 1370nm, 1390nm, 1410nm, 1430nm, 1410nm, 14140nm 1530nm, 1550nm, 1570nm, 1590nm ilaa 1610nm, halka 1310nm iyo 1490nm ay yihiin GPON Mowjadaha laba-geesoodka ah ee fiber-ka ee guriga, 1550nm waa hirarka baahinta caadiga ah ee ka kooban mawjadaha iyadoo la adeegsanayo cod-weyneeye fiber indhaha ah. Qalabka Nch CWDM mux ama qalabka de-mux-ga ee joogtada ah waa isku-xidhka N-1 cascading CWDM hal qalab filter.

Isgaarsiinta Fiber optic-ga ayaa beddeshay meerahaan tan iyo 1980-meeyadii. Halbeegga fiber-ka ah wuxuu leeyahay faa'iidooyinka dayactirka fudud, attenuation hooseeya, baaxadda hirarka dhererka indhaha ee ballaaran iyo xogta xawaaraha sare ee mawjadaha dhererka indhaha. Intaa waxaa dheer, fiberku wuxuu leeyahay xasillooni sare oo isbeddelka heerkulka iyo deegaanno kala duwan. Xidhiidhka Fiber optic-ga ayaa ciyaaraya door muhiim ah laga bilaabo isweydaarsiga macluumaadka qaaradaha ilaa madadaalada qoyska. Aaladaha WDM, Fiber-kala-qeybiyeyaasha iyo xirmooyinka fiber-ka ayaa ah qaybaha muhiimka ah ee shabakadda indhaha ee dadban (PON), oo taageeraya hirarka mowjadaha indhaha ee badan ee wadashaqeynta min hal dhibic ilaa dhibcaha badan ee codsiyada labada dhinac ah. Iyada oo ay weheliso hal-abuurka qaybaha firfircoon sida laser, photodiode, APD iyo amplifier indhaha, qaybaha fiber optic-ga ee dadban ayaa ka dhigaya fiilada fiber-ka laga heli karo albaabka guriga macaamiisha qiimo jaban. Intarneet xawaarihiisu sarreeyo, fiidyowyo HD ah oo fiidyow ah oo fidiya oo kor u kaca fiber ayaa meerahan ka dhigaya mid yar.

Aaladda CWDM waxa loo isticmaali karaa sidii qalab gooni-gooni ah ama waxa lagu dhex dhejin karaa laysarka iyo photodiode. Xirmada caanka ah waa saddex tubbada pigtail fiber, sanduuqa caagga ah ee cajaladda, guryaha LGX iyo 19 "1RU chassis.
