DWDMsiv 100GHz lossis 50GHz ib ntus, thiab tuaj yeem txhawb nqa 40 lossis 80 nthwv dej. Lub 100GHz lossis 50GHz lub sijhawm ntawm no sib raug rau cov wavelength cuam tshuam. Cov fiber ntau kho qhov muag muaj ob qhov ntev-wavelength qis-tsawg qhov rais, lub qhov rais 1310nm thiab 1550nm qhov rais, ob qho tib si tuaj yeem siv rau kev xa xov hluav taws xob, tab sis vim tias feem ntau siv erbium-doped fiber ntau amplifiers ua haujlwm nyob rau hauv lub wavelength ntawm 192.1 mus rau 196.1 tzs. Tsuas yog nyob ib ncig ntawm 1550nm qhov rais.
Yog li ntawd, kev khiav hauj lwm wavelength cheeb tsam ntawm optical wavelength division multiplexing system yog 192.1 ~ 196.1 THz. Yog xav paub ntxiv, xa mus rau ITU-T G.692 cov cai. Feem ntau, C-band lossis L-band feem ntau yog siv.
