CWDM-55 bụ 1550nm CWDM mux ma ọ bụ ngwaọrụ demux nwere nzacha 1550nm arụnyere n'ime ya nke na-agbakwunye akara 1550nm na ọdụ ụgbọ mmiri com ma ọ bụ tụfuo akara ngosi 1550nm site na ọdụ ụgbọ mmiri com. CWDM-xx usoro ngwaọrụ dị mma ịgbakwunye ma ọ bụ dobe xx CWDM ọwa na eriri optic usoro. Ogologo ogologo ogologo CWDM sitere na 1270nm, 1290nm, 1310nm, 1330nm, 1330nm, 1350nm, 1370nm, 1390nm, 1410nm, 1430nm, 1414nm, 1450nm 1530nm, 1550nm, 1570nm, 1590nm ruo 1610nm, ebe 1310nm na 1490nm bụ GPON Ogologo ụzọ anya ụzọ abụọ maka eriri n'ụlọ, 1550nm bụ ogologo ọdịnaya mgbasa ozi na-ahụkarị site na ngwa nke amplifier fiber optical. Ngwa Nch CWDM mux ma ọ bụ de-mux mgbe niile bụ nchịkọta N-1 cascading CWDM otu ngwaọrụ nzacha.

Nzikọrịta fiber optic agbanweela ụwa a kemgbe 1980s. Single mode eriri nwere uru nke mfe mmezi, ala attenuation, wide optical wavelength nso na elu ọsọ data na nke ọ bụla ngwa anya wavelength. Tụkwasị na nke ahụ, eriri nwere nkwụsi ike dị elu na mgbanwe okpomọkụ na gburugburu ebe dị iche iche. Nzikọrịta fiber optic na-arụ ọrụ dị mkpa site na mgbanwe ozi na kọntinent na ihe ntụrụndụ ezinụlọ. Ngwa WDM, Fiber splitters na fiber patchcords bụ isi ihe dị na netwọọkụ anya ngwa anya (PON), na-akwado multi optical wavelengths na-arụkọ ọrụ site n'otu ebe ruo ọtụtụ isi ngwa ụzọ abụọ. Yana mgbakwunye na ihe ọhụrụ na ihe ndị na-arụ ọrụ dị ka laser, photodiode, APD na amplifier ngwa anya, akụrụngwa fiber optic na-eme ka eriri eriri dị n'ọnụ ụzọ ụlọ ndị debanyere aha na ọnụ ọnụ ọnụ.
