I le fausiaina o fesoʻotaʻiga faʻapitonuʻu (aemaise lava mamao mamao OTN fesoʻotaʻiga fesoʻotaʻiga), o meafaigaluega e telexing vaevaega umi e taua tele. DWDM mafiafia galu vaevaega multiplexing meafaigaluega e mamao-mamao, maualuga-bandwidth gafatia felauaiga; CWDM gaogao gaogao vaevaega multiplexing meafaigaluega ei ai se tau maualalo. O lea pe afai e te filifilia le sa'o wavelength vaevaega multiplexing meafaigaluega e fausia ai se faiga feaveai opitika tau-lelei?

O le a le eseesega i le vaCWDM/DWDM Multiplexer?

I le taimi nei, o le auala aoga e foia ai le faʻaauau pea o faʻasalalauga faʻasalalau faʻamatalaga o le faʻaogaina lea o le CWDM wavelength division multiplexing equipment ma DWDM wavelength division multiplexing equipment, ae e eseese i le tele o itu.

(1) Avanoa vaeluaga i le va o le CWDM wavelength vaevaega masini multiplexing ma DWDM wavelength vaevaega masini multiplexing.

O le va o alalaupapa o lo'o fa'amatalaina o le eseesega i le va'aiga masani o le va'aiga i le va o laina va'aia e lua, ma e masani ona fa'aoga e taofia ai le fa'alavelave va'aia. CWDM wavelength division multiplexing mea faigaluega e sili atu le avanoa nai lo DWDM wavelength division multiplexing equipment. E mafai ona tuʻuina atu 18 galu umi i se faʻasologa faʻaaliga mai le 1271 nm i le 1611 nm faʻatasi ai ma le va o le 20 nm. O le DWDM wavelength division multiplexing equipment e mafai ona tuʻuina atu 40, 80 poʻo 160 wavelengths, ma o le vaeluaga o le ala e mafai ona 0.8 nm.

(2) Faʻasalalau le mamao i le va o le CWDM wavelength division multiplexing equipment ma DWDM wavelength division multiplexing equipment

Talu ai ona o le umi o le galu o le tele o le galu o le vaevaega o meafaigaluega (DWDM) e maualuga le tuʻufaʻatasia i le faʻaogaina o le fiber, o le DWDM wavelength division multiplexing meafaigaluega e mafai ona faʻasalalau mamao atu nai lo le CWDM wavelength division multiplexing equipment. CWDM wavelength vaevaega multiplexing meafaigaluega i le taimi nei e le mafai ona ausia le faatapulaaina felauaiga mamao, ma lona mamao tele felauaiga mamao e na o le 160 kilomita, ae o le mamao auina atu o DWDM wavelength vaevaega multiplexing meafaigaluega mamao atu nai lo le CWDM wavelength vaevaega multiplexing meafaigaluega.

(3) Fa'atonu lasers o le CWDM wavelength division multiplexing equipment ma DWDM wavelength division multiplexing equipment

Ole faiga ole CWDM wavelength division multiplexing equipment e maualalo mana'oga ile fa'ailoga fa'apitoa ole laser, ma e masani ona fa'aaogaina se laser uncooled; O le faiga o DWDM wavelength vaevaega multiplexing meafaigaluega e manaʻomia le faʻaogaina o le laser malulu, ma le faʻamafanafana leisa e faʻaaogaina se metotia o le fetuunaiga o le vevela e faʻamautinoa ai o le DWDM e sili atu le faʻatinoga, maualuga le saogalemu ma le umi o le auaunaga, o lea DWDM wavelength division multiplexer E faʻaaogaina le tele o le malosi. nai lo CWDM wavelength vaevaega multiplexing meafaigaluega e faʻaaoga ai lasers uncooled

(4) Tau o le CWDM wavelength division multiplexing equipment ma DWDM wavelength division multiplexing equipment

O le faiga o le DWDM wavelength vaevaega multiplexing meafaigaluega e le tutusa le tufatufaina o le vevela i le lautele o le galu, o lea pe a faʻaaogaina le faʻamafanafana leisa tekinolosi e fetuunai ai le vevela, o le tau faʻaaogaina o le faiga o DWDM wavelength vaevaega multiplexing meafaigaluega ua faateleina. E le gata i lea, o le faiga ole DWDM wavelength division multiplexing meafaigaluega e masani lava fa i le lima taimi sili atu le taugata nai lo le faiga ole CWDM wavelength division multiplexing meafaigaluega. Ae ui i lea, faʻatasi ai ma le faʻateleina o le lauiloa o le tele o galu o le galu (DWDM), o le tau o le DWDM opitika modules e toetoe lava 20% -25% maualalo ifo nai lo le CWDM optical modules.
