Site na mmepe na-aga n'ihu nke ụlọ ọrụ nkwurịta okwu anya, teknụzụ ọhụrụ na ngwọta na-echekwa ọnụ ahịa na-anọgide na-enweta.Dịka ọmụmaatụ, ngwaahịa CWDM na DWDM na-ejikarị eme ihe, yabụ taa, anyị ga-amụta banyere ngwaahịa CWDM na DWDM!
CWDM bụ teknụzụ nnyefe WDM dị ọnụ ala maka oghere ohere nke netwọkụ mpaghara mepere emepe.Na-echekwa ego fiber na ọnụ ahịa netwọk nke ọma, ọ na-edozi nsogbu abụọ nke ụkọ fiber na nnyefe transperent nke ọtụtụ ọrụ.Enwere ike iwulite netwọkụ ahụ yana enwere ike ịme azụmahịa ahụ n'ime obere oge.
Uru nke CWDM:
※ Uru kachasị mkpa nke CWDM bụ ọnụ ala akụrụngwa.
※ Ọ nwere ike ibelata ụgwọ ọrụ nke netwọkụ.
※ Ọ nwere ike ịbawanye ikike nnyefe nke eriri anya ma melite ojiji nke akụrụngwa eriri anya.
※ Obere nha na obere ike oriri.
※ nwere ezigbo mgbanwe na scalability
DWDM nwere ike ijikọ na bufee dị iche iche wavelengths n'otu eriri n'otu oge.Ka ọ dị irè, a na-atụgharị otu eriri ka ọ bụrụ ọtụtụ eriri mebere.DWDM na-enwekarị ụdị ngwa abụọ: mepere DWDM na DWDM agbakwunyere.
Uru nke DWDM:
※ Usoro ya na ọsọ nnyefe adịghị mkpa.
※ A na-eji multiplexer na splitter nke sistemu DWDM agbakwunyere iche iche na nnyefe na nnata.
※ Ngwa DWDM agbakwunyere nwere usoro dị mfe yana obere olu, naanị ihe dị ka otu ụzọ n'ụzọ ise nke oghere DWDM mepere emepe, na-echekwa akụrụngwa ime ụlọ kọmputa.
※ Usoro DWDM agbakwunyere na-eji naanị ihe ndị na-agafe agafe (dịka multiplexers ma ọ bụ demultiplexers) na njedebe nnata na nnyefe.Ndị na-ahụ maka ekwentị nwere ike ịnye iwu ozugbo site n'aka ndị na-emepụta ngwaọrụ, na-ebelata njikọ ọkọnọ na ọnụ ala dị ala, si otú a na-echekwa ọnụ ahịa akụrụngwa.
CWDM na DWDM bụ multiplexers nkewa wavelength, yabụ kedu ihe dị iche n'etiti ha?CWDM (ie, sparse wavelength division multiplexing) na DWDM (ya bụ, nnukwu ogologo nkewa nkewa multiplexing), n'ụzọ nkịtị anyị nwere ike ịhụ ihe dị iche n'etiti ha abụọ: "ok" na "sparse".Sparse Wavelength Division Multiplexing, dị ka aha ahụ na-egosi, bụ ezigbo onye ikwu nke Dense Wavelength Division Multiplexing.
Esemokwu ha na-apụtakarị n'isi ihe atọ ndị a:
1) CWDM na-ebu ọwa spacing dịtụ obosara, ya mere, nanị 5 ka 6 wavelengths nke ìhè ebili mmiri nwere ike multiplexed na otu ngwa anya eriri, na ihe dị iche n'etiti "sparse" na "ok" aha si na nke a;
2) CWDM modulated laser na-eji laser adịghị mma, ebe DWDM na-eji laser jụrụ oyi.Laser jụrụ oyi na-eji ntugharị okpomọkụ, na laser adịghị mma na-eji nlegharị anya eletrọnịkị.CWDM na-ewu ewu ugbu a n'etiti ndị na-eweta ngwa ụlọ ọrụ izugbe.N'ikwu ya n'ụzọ dị mfe: DWDM bụ nkewa nke CWDM.
3) The akụrụngwa eji gburugburu ebe obibi dị iche iche.A na-ejikarị CWDM eme ihe na oyi akwa convergence na oghere ohere;A na-eji DWDM na gburugburu ebe ọrụ nkwukọrịta ụgbọ oloko.
