Itandukaniro riri hagati ya CWDM na DWDM

Bitewe n’iterambere rihoraho ry’inganda zikora itumanaho rya optique, ikoranabuhanga rishya n’ibisubizo bigabanya ikiguzi bikomeje kuboneka. Urugero, ibicuruzwa bya CWDM na DWDM bikomeje gukoreshwa cyane, bityo uyu munsi tuziga ku bicuruzwa bya CWDM na DWDM!

CWDM ni ikoranabuhanga rihendutse ryo kohereza WDM ku rwego rworoshye rwo kugera ku muyoboro w’umujyi. Rizigama neza umutungo wa fibre n’ikiguzi cy’imiyoboro, rikemura ibibazo bibiri by’ibura rya fibre no kohereza serivisi nyinshi mu buryo bugaragara. Umuyoboro urashobora kubakwa kandi ubucuruzi bugakorwa mu gihe gito.

Ibyiza bya CWDM:

※ Akamaro k'ingenzi ka CWDM ni igiciro gito cy'ibikoresho.

※ Bishobora kugabanya ikiguzi cy'imikorere y'umuyoboro.

※ Bishobora kongera cyane ubushobozi bwo kohereza fibre optique no kunoza ikoreshwa ry'umutungo wa fibre optique.

※ Ingano nto kandi ikoresha ingufu nke.

※ Ifite ubushobozi bwo koroshya ibintu no kwaguka neza

DWDM ishobora guhuza no kohereza uburebure butandukanye bw'uburebure muri fibre imwe icyarimwe. Kugira ngo igire akamaro, fibre imwe ihindurwamo fibre nyinshi. DWDM ubusanzwe ifite uburyo bubiri bwo kuyikoresha: DWDM ifunguye na DWDM ihuriweho.

Ibyiza bya DWDM:

※ Porotokole yayo n'umuvuduko wayo wo kohereza amakuru ntacyo bitwaye.

※Multiplexer na splitter bya sisitemu ya DWDM ihuriweho bikoreshwa ukwabyo kuri transmitter na receiver

※ Ibikoresho bya DWDM bihujwe bifite imiterere yoroshye n'ingano nto, hafi kimwe cya gatanu cy'umwanya ukoreshwa na DWDM ifunguye, bigatuma ibikoresho byo mu cyumba cya mudasobwa bizigamwa.

※Sisitemu ya DWDM ihuriweho ikoresha gusa ibice bidakora (nk'ibice bikoresha ibikoresho byinshi cyangwa ibikoresha byinshi) mu kwakira no kohereza. Abakora itumanaho bashobora gutumiza ibikoresho mu buryo butaziguye, bakagabanya imiyoboro y'ibikoresho kandi bakagabanya ikiguzi, bityo bakagabanya ikiguzi cy'ibikoresho.

CWDM na DWDM byombi ni multiplexers zo kugabanya uburebure bw'umuraba, none se itandukaniro riri hagati yabyo ni irihe? CWDM (ni ukuvuga multiplexing ya sparse wavelength division) na DWDM (ni ukuvuga dense wavelength division multiplexing), mu by'ukuri dushobora kubona itandukaniro riri hagati ya byombi: "dense" na "sparse". Sparse Wavelength Division Multiplexing, nk'uko izina ribigaragaza, ni isano ya hafi ya Dense Wavelength Division Multiplexing. 

Itandukaniro ryabo rigaragarira ahanini mu ngingo eshatu zikurikira:

1) Intera y'umuyoboro w'amashanyarazi wa CWDM ni nini cyane, bityo, ni hagati ya 5 na 6 gusa by'imiraba y'urumuri ishobora gukwirakwizwa kuri fibre imwe y'urumuri, kandi itandukaniro riri hagati y'amazina "aciriritse" n' "afite ubucucike" rituruka kuri ibi;

2) Lazeri ikoreshwa mu gukosora CWDM ikoresha lazeri itarakonjeshwa, mu gihe DWDM ikoresha lazeri ikonjeshwa. Lazeri ikonjeshwa ikoresha uburyo bwo gukosora ubushyuhe, naho lazeri itarakonjeshwa ikoresha uburyo bwo gukosora ikoranabuhanga. CWDM ubu ikunzwe cyane n'abatanga porogaramu rusange mu bigo. Mu magambo make: DWDM ni igice kimwe cya CWDM.

3) Imiterere y'ibikoresho iratandukanye. CWDM ikoreshwa cyane cyane mu gice cy'aho bihurira n'aho binjirira; DWDM ikoreshwa mu gice cy'itumanaho rya gari ya moshi.
