He aha te kōwae whatu DWDM?

Ka taea te whakamahi i te hangarau Whakarea Wehenga Roangaru Matotoru (DWDM) i roto i ngā momo whatunga whakawhitiwhiti kōrero, tae atu ki ngā whatunga tuara tawhiti, ngā whatunga rohe tāone nui (MAN), ngā whatunga urunga noho, me ngā whatunga rohe ā-rohe (LAN).

I roto i ēnei tono, inā koa ko ngā MAN, he maha ngā wā ka tāutahia ngā momo kōwae whatu iti (SFP) me ētahi atu momo kōwae whatu ki ngā momo āhua kiato-teitei. Koinei te take e tino hiahia ana te tangata ki ngā whakawhiti whatu DWDM. Ma tēnei akoranga koe e kōrero mō te tirohanga whānui o ngā kōwae whatu DWDM, ā, ka whakamōhio atu ki a koe ki ngā otinga kōwae whatu DWDM a Beiyi Fibercom (WWW.F-TONE.COM).

He aha te kōwae whatu DWDM?

E ai ki tōna ingoa, ko te kōwae whatu DWDM he kōwae whatu e whakakotahi ana i te hangarau DWDM. Ka whakamahia e te kōwae whatu DWDM ngā roangaru rerekē hei whakakotahi i ngā tohu whatu maha ki roto i te muka whatu kotahi, ā, kāore tēnei mahi e pau te hiko. Kua hangaia ēnei kōwae whatu mō te tuku tawhiti-roa, kaha-teitei, ka taea te tere ki te 10GBPS, ā, ka taea te tawhiti mahi ki te 120KM. I taua wā anō, kua hangaia te kōwae whatu DWDM kia rite ki te paerewa Whakaaetanga Maha-Rohe (MSA) hei whakarite i te whānuitanga o te hototahitanga o ngā taputapu whatunga. Ka tautokohia e ngā kōwae whatu 10G DWDM te ESCON, ATM, Fiber Channel me te 10 Gigabit Ethernet (10GBE) i runga i ia tauranga. Ko ngā kōwae whatu DWDM kei te mākete ko: DWDM SFP, DWDM SFP+, DWDM XFP, DWDM X2 me ngā kōwae whatu DWDM XENPAK, me ētahi atu.

Te mahi me te mātāpono mahi o te kōwae whatu DWDM

He rite tonu te mahi matua me te kaupapa mahi a te waeine whatu DWDM ki ētahi atu waeine whatu, e huri ana i ngā tohu hiko hei tohu whatu, kātahi ka huri i ngā tohu whatu hei tohu hiko. Heoi, kua hangaia te waeine whatu DWDM mō ngā tono DWDM, ā, he mea tika kia whakahuatia he āhuatanga me ngā mahi anō ōna. Ki te whakatauritea ki te waeine whatu coarse wavelength division multiplexing (CWDM), kua hangaia te waeine whatu DWDM mō te muka aratau-kotahi, ā, e ai ki te ITU-T, kei roto i te awhe ingoa DWDM o te 1528.38 ki te 1563.86NM (hongere 17 ki te hongere 61). Ka mahi i waenga i ngā roangaru. Ka whakamahia hei whakatakoto i roto i ngā taputapu whatunga DWDM o te urunga tāone me te whatunga matua. Kei roto he hononga SFP 20-pine mō te mahi whakawhiti-wera. Ka whakamahia e tana wāhanga tuku he taiaho DFB puna maha-kuantum DWDM, he taiaho e tutuki ana i te Akomanga 1 e ai ki te paerewa haumaru o te ao IEC-60825. Hei tāpiritanga, ko ngā kōwae whatu DWDM mai i te maha o ngā kaiwhakarato e tutuki ana i te paerewa SFF-8472 MSA. Ko ngā mahi auaha hou i roto i ngā pūnaha tuku DWDM ko ngā kōwae whatu mono, ka taea te whakarerekē ka taea te mahi i runga i ngā hongere 40, 80 rānei. Mā tēnei whakatutukitanga ka tino whakaitihia te hiahia mō ngā kōwae mono motuhake ina ka taea anake te whakahaere i te whānuitanga katoa o ngā roangaru me ētahi taputapu mono torutoru i konei, i reira.

Te whakarōpūtanga o ngā kōwae whatu DWDM

I te nuinga o te wā, ina kōrero tātou mō ngā kōwae whatu DWDM, ka kōrero tātou mō ngā kōwae whatu DWDM Gigabit, 10 Gigabit rānei. E ai ki ngā momo takai rerekē, ka taea te wehewehe i ngā kōwae whatu DWDM ki ngā momo e rima. Ko ēnei: ​​DWDM SFP, DWDM SFP+, DWDM XFP, DWDM X2, me ngā kōwae whatu DWDM XENPAK.
