Te rerekētanga i waenga i te CWDM me te DWDM

I te whanaketanga tonu o te umanga whakawhitiwhiti kōrero whatu, kei te puta tonu mai ngā hangarau hou me ngā otinga penapena utu. Hei tauira, kei te whānui haere te whakamahinga o ngā hua CWDM me DWDM, nō reira i tēnei rā ka ako tātou mō ngā hua CWDM me DWDM!

He hangarau tuku WDM iti te utu a te CWDM mō te paparanga urunga o te whatunga rohe tāone nui. He pai te penapena rauemi muka me ngā utu whatunga, ā, ka whakatauhia ngā raruraru e rua o te korenga o te muka me te tuku mārama o ngā ratonga maha. Ka taea te hanga i te whatunga, ā, ka taea te whakahaere pakihi i roto i te wā poto.

Ngā Painga o te CWDM:

※ Ko te painga nui o te CWDM ko te iti o te utu o ngā taputapu.

※ Ka taea te whakaiti i te utu whakahaere o te whatunga.

※ Ka taea e ia te whakanui ake i te kaha tuku o te muka whatu me te whakapai ake i te whakamahinga o ngā rauemi muka whatu.

※ He iti te rahi, he iti hoki te whakamahinga hiko.

※ He ngāwari, he tauine hoki

Ka taea e te DWDM te whakakotahi me te tuku i ngā roangaru rerekē i roto i te muka kotahi i te wā kotahi. Kia whai hua ai, ka hurihia te muka kotahi ki ngā muka mariko maha. E rua ngā momo tono a te DWDM: ko te DWDM tuwhera me te DWDM whakauru.

Ngā Painga o te DWDM:

※ Kāore he pānga o tōna kawa me te tere tuku.

※Ka whakamahia motuhaketia te multiplexer me te splitter o te pūnaha DWDM whakauru i te tuku me te kaiwhiwhi

※ He hanganga māmā noa iho ngā taputapu DWDM whakauru, ā, he iti ake te rahinga, tata ki te kotahi haurima noa iho o te wāhi e nohoia ana e te DWDM tuwhera, e penapena ana i ngā rauemi rūma rorohiko.

※Ka whakamahia noa e te pūnaha DWDM whakauru ngā wāhanga kore mahi (pērā i ngā multiplexers, i ngā demultiplexers rānei) i ngā pito whiwhi me te tuku. Ka taea e ngā kaiwhakahaere waea te tuku ota tika mai i ngā kaihanga taputapu, ka whakaiti i ngā hononga tuku me ngā utu iti iho, ā, ka penapenahia ngā utu taputapu.

He maha ngā momo wehewehenga roangaru te CWDM me te DWDM, nō reira he aha te rerekētanga i waenganui i a rāua? Ko te CWDM (arā, te wehewehenga roangaru papatahi) me te DWDM (arā, te wehewehenga roangaru matotoru), ka kitea tata te rerekētanga i waenganui i ngā mea e rua: "matua" me te "papatahi". Ko te Wehenga Roangaru Papatahi, e ai ki te ingoa, he whanaunga tata ki te Wehenga Roangaru Matotoru. 

Ko ō rātou rerekētanga e kitea nuitia ana i roto i ngā āhuatanga e toru e whai ake nei:

1) He whānui te tawhiti o ngā hongere kawe CWDM, nō reira, e 5 ki te 6 noa iho ngā roangaru o ngā ngaru mārama ka taea te whakarea i runga i te muka whatu kotahi, ā, ko te rerekētanga i waenga i ngā ingoa "takataka" me te "mātotoru" i ahu mai i tēnei;

2) Ka whakamahia e te taiaho whakarerekē CWDM te taiaho kāore i whakamataohia, ko te DWDM ia ka whakamahia e te taiaho whakamataohia. Ka whakamahia e te taiaho whakamataohia te whakatikatika pāmahana, ā, ka whakamahia e te taiaho kāore i whakamataohia te whakatikatika hiko. He tino rongonui te CWDM i waenga i ngā kaiwhakarato tono umanga whānui. He māmā noa iho: Ko te DWDM he wāhanga iti o te CWDM.

3) He rerekē te taiao whakamahi taputapu. Ko te CWDM te nuinga e whakamahia ana i roto i te paparanga huihuinga me te paparanga urunga; ko te DWDM te mea e whakamahia ana i roto i te taiao mahi whakawhitiwhiti kōrero rerewē.
