He aha te CWDM?
-I roto i nga whakawhitiwhitinga muka-a-whatu, ko te WDM-roa-ngaru he hangarau e whakatiki ana i te maha o nga tohu kawe whatu ki runga i te muka whatu kotahi ma te whakamahi i nga roangaru rereke (ara, tae) o te rama laser. Ma tenei tikanga ka taea te whakawhitiwhiti korero takirua i runga i te whenu kotahi o te muka, e kiia ana ko te roangaru-waahanga mataruarua, me te whakareatanga o te kaha.
-Ko te ingoa katoa o CWDM ko Coarse Wavelength Division Multiplexing.
-E ai ki te ingoa, he ahua o te muka optics maha, no reira ka taea e nga whatunga CWDM te tuku korero tukutahi, rua-ara.
-Ko te kupu “maroke” e pa ana ki te mokowhiti roangaru i waenganui i nga hongere.
-Ka whakamahia e te CWDM nga tohu laser e rereke ana i nga waahanga o te 20 nm. He 18 nga waahana rereke e waatea ana - me te awhe roangaru mai i te 1610 nm ki te 1270 nm - me te 8 ka taea te whakamahi i roto i te punaha kotahi. I te mea ka taea e ia hongere te reiti raraunga 3.125 Gbps, ko te kaha whakahiato he 10 Gbps mo tetahi taura CWDM.
-Ka whakamahia te CWDM mo te utu iti, te iti o te kaha (sub-10G) me nga tono tawhiti poto he mea nui te utu.
-He pai te CWDM mo nga whatunga tere me te roa e kore e hiahia kia nui ake te utu. He pai hoki mo te whakamohoatanga o nga punaha tawhito.
-Ka taea e CWDM to raina ngawari e pupuri ana i o whiringa ka tuwhera, engari ka taea tonu e koe te whakamahi i etahi atu hoahoa taura ka puta te hiahia.
Painga:
- Iti me te marama, Ahumahi, ka taea te whakanoho ngawari;
- Mono me te purei, ngawari te whakauru me te tiaki, kaore he whirihoranga;
- Kore tuku roa, whakapai ake i te mahi tuku, tautoko i te tawhiti atu;
- Mo nga whatunga muka whatu, kaore e hiahiatia he mana, he pono nui, tautoko i te tono o waho;
- Kia marama ki nga tohu ratonga, ka taea te tautoko i te FE/GE/10GE/25GE/100GE, OTU1/OTU2/OTU3, FC1/2/4/8/10, STM1/4/16/64, me etahi atu;
