CWDM/DWDMka hoʻohana ʻana i nā lako hana hoʻohana ʻana i ka hawewe lōʻihiKe piʻi aʻe nei nā koi o nā kānaka no ka bandwidth, Dense Wavelength Division Multiplexing (DWDM) ua holomua nui nā mea hana i ka hōʻemi ʻana i nā kumukūʻai, a no laila ua makemake nui ʻia ma ka mākeke. Eia nō naʻe, nā lako hoʻoheheʻe ʻana o ka hawewe lōʻihi (CWDM) ʻoi aku ka maikaʻi o ke kumukūʻai kiʻekiʻe ma nā hiʻohiʻona kahi haʻahaʻa haʻahaʻa o ka pilina ma mua o 10G a me ka hoʻouna ʻana i kahi pōkole. I ke kūkulu ʻana i ka ʻikepili haʻahaʻa haʻahaʻa, ʻo ia ka mea hiki ke hana i kēia manawa.ʻO ka hoʻoili ʻia ʻana o ka hawewe nalu CWDM/DWDM i nā mea hana multiplexingLoaʻa i nā mea hana hoʻoheheʻe nalu CWDM a me ka DWDM wavelength division multiplexing lako i kā lākou pono ponoʻī i nā pūnaewele OTN. ʻO nā mea maikaʻi o ka CWDM wavelength division multiplexing lako hiki iā ia ke hoʻohana i nā lasers manaʻo haʻahaʻa haʻahaʻa i hāʻawi ʻia ʻaʻole pono e hoʻomaha a me nā kumukūʻai haʻahaʻa. ʻO ka kānana passive, no laila ua hoʻohana nui ʻia ka ʻōnaehana hawewe nalu CWDM i kēia manawa i ka DWDM wavelength division multiplexing equipment system. ʻOiai hiki ke hoʻohana ʻia ka ʻenehana CWDM i nā ʻōnaehana DWDM no ka hoʻohana ʻana i nā modula optical ʻoi aku ka liʻiliʻi, ʻoi aku ka nui o ka spacing channel CWDM, no laila e hoʻemi ʻia ka helu o nā nalu i loaʻa i ka ʻōnaehana, a ke kaupalena nei kēia i ka hiki ke hoʻouna ʻia o ka ʻōnaehana, no laila i kahi ʻO kekahi I kekahi ʻano, ʻaʻole hiki iā ia ke hoʻomau i nā lako hana hoʻokaʻawale ʻole DWDM.
