Mu iyubakwa ry'imiyoboro y'akarere ka metropolitani (cyane cyane intera ndende ya OTN ya optique yohereza imiyoboro), ibikoresho byo kugabana imirongo yumurongo ni ngombwa cyane. Ibikoresho bya DWDM byuzuye bigabanya ibikoresho bifite intera ndende, ubushobozi bwogukwirakwiza cyane; Ibikoresho bya CWDM bigabanya ibikoresho bigabanya ibikoresho bifite igiciro gito. Noneho niba uhisemo uburyo bukwiye bwo kugabana ibikoresho byinshi kugirango wubake sisitemu yohereza optique?

Ni irihe tandukaniro riri hagatiCWDM / DWDM Multiplexer?

Kugeza ubu, uburyo bwiza bwo gukemura ikibazo cyiyongera cyogukwirakwiza amakuru kwaguka ni ugukoresha ibikoresho bya CWDM bigabanya ibikoresho byinshi hamwe nibikoresho bya DWDM bigabanya ibikoresho, ariko biratandukanye mubice byinshi.

Umwanya wumuyoboro usobanurwa nkitandukaniro ryumubare wabatwara izina hagati yimiyoboro ibiri yegeranye, kandi ikoreshwa muburyo bwo gukumira imiyoboro ihuza imiyoboro. Ibikoresho bya CWDM bigabanya ibikoresho byinshi bifite intera yagutse kuruta ibikoresho bya DWDM bigabanya ibikoresho. Irashobora kohereza uburebure bwa 18 bwumurongo muri gride ya ecran kuva kuri 1271 nm kugeza kuri 1611 nm hamwe numuyoboro wa 20 nm. Ibikoresho bya DWDM bigabanya ibikoresho byinshi birashobora kohereza uburebure bwa 40, 80 cyangwa 160, kandi intera y'umuyoboro irashobora kuba 0.8 nm.

Kuberako uburebure bwumurambararo wibikoresho byinshi (DWDM) byinjijwe cyane muburyo bwo kohereza fibre optique, ibikoresho bya DWDM bigabanya ibikoresho byinshi bishobora kohereza intera ndende kuruta ibikoresho bya CWDM bigabanya ibikoresho. Ibikoresho bya CWDM bigabanya ibikoresho byinshi bigezweho kuri ubu ntibishobora kugera ku ntera itagira imipaka, kandi intera ntarengwa yohereza ni kilometero 160 gusa, mu gihe intera yo kohereza ibikoresho bya DWDM bigabanya ibikoresho byinshi bigereranywa cyane n’ibikoresho bya CWDM bigabanywa.

Sisitemu ya CWDM igabanya ibikoresho bigabanya ibikoresho bifite ibisabwa bike kubipimo bya tekinike ya laser, kandi muri rusange ikoresha lazeri idakonje; Sisitemu ya DWDM igabanya ibikoresho bigabanya ibikoresho bikenera gukoresha lazeri ikonjesha, kandi laser yo gukonjesha ikoresha uburyo bwo guhindura ubushyuhe kugirango sisitemu ya DWDM igire imikorere myiza, umutekano muremure hamwe nubuzima bwa serivisi ndende, bityo DWDM igabanya umurongo wa Multlexer ikoresha ingufu nyinshi kurenza ibikoresho bya CWDM bigabanya ibikoresho byinshi ukoresheje lazeri idakonje

Sisitemu ya DWDM igabanya ibikoresho bigabanya ibikoresho bigabanya ubushyuhe budasanzwe muburyo bwagutse, bityo rero iyo tekinoroji yo gukonjesha ikoreshwa muguhindura ubushyuhe, ikiguzi cyo gukoresha sisitemu ya DWDM igabanya ibikoresho byiyongera. Mubyongeyeho, sisitemu yibikoresho bya DWDM bigabanya ibikoresho bigizwe ninshuro enye kugeza kuri eshanu zihenze kuruta sisitemu ya CWDM igabanya ibikoresho bigabanya ibikoresho. Ariko, hamwe no kwiyongera kwamamara ryikwirakwizwa ryinshi ryinshi (DWDM), igiciro cya moderi ya optique ya DWDM kiri hafi 20% -25% munsi yicyiza cya CWDM optique.
