He aha te CWDM?
-I roto i ngā whakawhitiwhitinga muka-whatu, ko te whakarea wehewehenga-roaroa (WDM) he hangarau e whakarea ana i te maha o ngā tohu kawe whatu ki runga i te muka whatu kotahi mā te whakamahi i ngā roangaru rerekē (arā, ngā tae) o te mārama taiaho. Mā tēnei tikanga ka taea te whakawhitiwhitinga taha-rua i runga i te aho muka kotahi, e kiia ana ko te whakarea wehewehenga-roaroaroa, me te whakarea hoki i te kaha.
-Ko te ingoa katoa o te CWDM ko te Coarse Wavelength Division Multiplexing.
-E ai ki te ingoa, he momo muka whatu maha-whakawhitiwhiti, nō reira ka taea e ngā whatunga CWDM te tuku whakawhitiwhiti kōrero rua-ara i te wā kotahi.
-Ko te kupu "mātotoru" e pā ana ki te mokowā o ngā roangaru i waenga i ngā hongere.
-Ka whakamahia e te CWDM ngā tohu taiaho e rerekē ana i roto i ngā pikinga o te 20 nm. E 18 katoa ngā hongere rerekē e wātea ana — me te awhe roangaru mai i te 1610 nm ki te 1270 nm — ā, e 8 ka taea te whakamahi i roto i te pūnaha kotahi. Nā te mea ka taea e ia hongere te kawe i ngā tere raraunga o te 3.125 Gbps, ko te kaha katoa he 10 Gbps mō tētahi taura CWDM.
-E whakamahia ana te CWDM mō ngā tono iti ake te utu, iti ake te kaha (iti iho i te 10G) me ngā tono tawhiti poto ake, ina he mea nui te utu.
-He pai rawa te CWDM mō ngā whatunga tere, roa hoki, kāore e hiahia ana ki ngā tere utu nui. He pai hoki mō te whakapai ake mārire i ngā pūnaha tawhito.
-Ka taea e te CWDM te noho hei taura ngāwari māu hei pupuri i ō kōwhiringa kia tuwhera tonu, engari ka taea tonu e koe te whakamahi i ētahi atu hoahoa taura mēnā e tika ana.
Ngā Painga:
- Iti, māmā hoki, ā-ahumahi, ka taea te whakanoho ngāwari;
- Monokia, ka purei, he ngāwari te tāuta me te tiaki, kāore he hiahia mō tētahi whirihoranga;
- Kāore he whakaroa tuku, ka whakapai ake i te mahi tuku, ka tautoko i te tawhiti atu;
- Mō ngā whatunga muka whatu kore mahi, kāore he hiko e hiahiatia ana, he tino pono, he tautoko i te tono o waho;
- Kia mārama ki ngā tohu ratonga katoa, ka taea te tautoko i te FE/GE/10GE/25GE/100GE, OTU1/OTU2/OTU3, FC1/2/4/8/10, STM1/4/16/64, me ētahi atu;
