Ihe dị iche n'etiti CWDM na DWDM

Site na mmepe na-aga n'ihu nke ụlọ ọrụ nkwukọrịta anya, teknụzụ ọhụrụ na ngwọta nchekwa ego ka na-aga n'ihu na-enweta. Dịka ọmụmaatụ, a na-eji ngwaahịa CWDM na DWDM eme ihe nke ukwuu, yabụ taa anyị ga-amụta maka ngwaahịa CWDM na DWDM!

CWDM bụ teknụzụ nnyefe WDM dị ọnụ ala maka oghere nnweta nke netwọk mpaghara obodo ukwu. Ọ na-echekwa akụrụngwa eriri na ọnụ ahịa netwọk nke ọma, ọ na-edozi nsogbu abụọ nke ụkọ eriri na nnyefe doro anya nke ọtụtụ ọrụ. Enwere ike iwulite netwọk ahụ ma nwee ike ịrụ ọrụ ahụ n'ime obere oge.

Uru nke CWDM:

※ Uru kachasị mkpa nke CWDM bụ obere ọnụ ahịa nke akụrụngwa.

※ Ọ nwere ike ibelata ọnụ ahịa ọrụ nke netwọk ahụ.

※ Ọ nwere ike ime ka ikike nnyefe nke eriri anya dịkwuo elu ma melite ojiji nke akụrụngwa eriri anya.

※ Obere nha na obere oriri ike.

※ Nwere ezigbo mgbanwe na nhazi

DWDM nwere ike ijikọta ma bufee ogologo ebili dị iche iche n'otu eriri n'otu oge. Iji mee ka ọ dị irè, a na-agbanwe otu eriri ka ọ bụrụ ọtụtụ eriri mebere emebe. DWDM na-enwekarị ụdị ngwa abụọ: meghee DWDM na DWDM agbakwunyere.

Uru nke DWDM:

※ Usoro ya na ọsọ nnyefe ya adịghị mkpa.

※A na-eji multiplexer na splitter nke sistemụ DWDM agbakwunyere iche na transmitter na receiver

※ Ngwaọrụ DWDM agbakwunyere nwere nhazi dị mfe yana obere olu, naanị ihe dị ka otu ụzọ n'ụzọ ise nke oghere DWDM mepere emepe bi, na-echekwa akụrụngwa ụlọ kọmputa.

※ Sistemụ DWDM agbakwunyere na-eji naanị ihe ndị na-anaghị arụ ọrụ (dịka multiplexers ma ọ bụ demultiplexers) na njedebe nnata na nnyefe. Ndị ọrụ telecom nwere ike itinye iwu ozugbo site n'aka ndị nrụpụta ngwaọrụ, na-ebelata njikọ ọkọnọ ma na-ebelata ọnụ ahịa, si otú a na-azọpụta ọnụ ahịa akụrụngwa.

CWDM na DWDM bụ multiplexers nkewa wavelength, yabụ kedu ihe dị iche n'etiti ha? CWDM (ya bụ, multiplexing nkewa wavelength sparse) na DWDM (ya bụ, dens wavelength division multiplexing), n'ụzọ nkịtị anyị nwere ike ịhụ ihe dị iche n'etiti ha abụọ: "dense" na "sparse". Sparse Wavelength Division Multiplexing, dịka aha ya si kwuo, bụ ezigbo onye ikwu nke Dense Wavelength Division Multiplexing. 

Isi ihe atọ ndị a na-egosipụtakarị ọdịiche ha:

1) Oghere ọwa CWDM dị oke obosara, ya mere, naanị ogologo ebili mmiri 5 ruo 6 nke ìhè ka enwere ike ịgbasa na otu eriri anya ahụ, ọdịiche dị n'etiti aha "sparese" na "decrease" sitere na nke a;

2) Laser CWDM modulated na-eji laser uncooled, ebe DWDM na-eji laser oyi. Laser oyi na-eji nhazi okpomọkụ, laser a na-anaghị ajụ oyi na-ejikwa nhazi eletrọniki. CWDM abụrụla ihe a ma ama ugbu a n'etiti ndị na-enye ngwa ụlọ ọrụ izugbe. N'ikwu ya n'ụzọ dị mfe: DWDM bụ nkewa CWDM.

3) Ebe eji akụrụngwa dị iche. A na-ejikarị CWDM eme ihe na oyi akwa njikọta na oyi akwa nnweta; a na-eji DWDM eme ihe na gburugburu ebe ọrụ nkwukọrịta ụgbọ okporo ígwè.
