64, feem ntau tsawg dua 10.
1. Nyob rau hauv txoj kev xav, 64 tuaj yeem txuas tau, tab sis xav txog qhov attenuation ntawm lub teeb thiab qhov rhiab heev ntawm onu rau lub teeb, nyob rau hauv kev siv dav dav, cov kev sib txuas ntawm ib qho chaw nres nkoj tsawg dua 10. Qhov siab tshaj plaws ntawm cov neeg siv nkag los ntawm olt yog feem ntau. txwv los ntawm peb yam xwm txheej, uas yog, tus naj npawb ntawm cov kev pabcuam bandwidth thiab MAC chaw nyob uas cov neeg siv tuaj yeem tau txais.
2.olt (optical kab davhlau ya nyob twg) kho qhov muag kab davhlau ya nyob twg.Hauv kev siv pon thev naus laus zis, olt cov cuab yeej yog cov cuab yeej tseem ceeb hauv chaw ua haujlwm.Lub luag haujlwm nws paub yog txuas rau pem hauv ntej-kawg hloov nrog lub network cable, hloov nws mus rau hauv lub teeb liab kho qhov muag, thiab siv cov khoom siv kho qhov muag los cuam tshuam nrog lub optical splitter ntawm tus neeg siv kawg.Paub txog kev tswj hwm, kev tswj hwm thiab kev ua haujlwm ntawm lub onu ntawm cov khoom siv davhlau ya nyob twg.Zoo li onu ntaus ntawv, lub olt ntaus ntawv kuj yog ib tug optoelectronic integrated ntaus ntawv.
3.onu (optical network unit) kho qhov muag node.onu muab faib ua active optical network unit thiab passive optical network unit.Feem ntau, cov cuab yeej nruab nrog kev saib xyuas network suav nrog optical receiver, uplink optical transmitter, thiab ntau tus choj amplifiers hu ua optical node.
