I ke kua o ka hoʻomohala wikiwiki ʻana i nā ʻoihana pūnaewele, ke kū nei ka ʻoihana kelepona i kahi pilikia ulu koʻikoʻi. ʻO kekahi o nā ʻenehana koʻikoʻi i nā kamaʻilio optical - Wavelength Division Multiplexing (WDM) - ua lilo i mea nui no ka lanakila ʻana i kēia mau palena kino.

Inā hoʻohālikelike ʻia ke kaula uila optical me ke alaloa nui, ua like ke kamaʻilio kuʻuna me kahi kaʻa hoʻokahi e noho ana ma ke alanui holoʻokoʻa. Hoʻokaʻawale maoli ka ʻenehana WDM i kēia ala kino i nā "alanui virtual" he nui ʻaʻole e hoʻopilikia (nā nalu optical like ʻole), e ʻae ana i nā hōʻailona ʻikepili he nui e hoʻouna ʻia i ka manawa like ma o ka kaula uila like. ʻO ka lako paʻa e hiki ai i kēia ʻenehana ʻo ia ka kānana passive DWDM (Dense Wavelength Division Multiplexing). Hāʻawi kēia ʻatikala i kahi loiloi pōkole o kēia ʻenehana.

I. Nā Kumumanaʻo Koʻikoʻi a me nā Pōmaikaʻi o nā Kānana Passive

DWDM Passive, OSP Ring OADM, 1 Channel, 100 GHz Spacing, Channel 48, 900um 1m Fiber, SC/APC Connector

ʻO ke ʻano o ka huaʻōlelo "passive" ʻaʻole pono ka hāmeʻa i kekahi lako mana o waho. Akā, hilinaʻi nui ia i nā uhi ʻili lahilahi optical kikoʻī a i ʻole nā ​​​​​​hale grating e hoʻokaʻawale pololei (demultiplex) a i ʻole e hoʻohui (multiplex) i nā hōʻailona optical o nā nalu like ʻole.

Hāʻawi kēia ʻano optical kino wale nō i ke kūpaʻa a me ka hilinaʻi kūikawā, e hoʻolilo ana i ka hāmeʻa i mea kūpaʻa loa i ka hoʻopilikia electromagnetic. ʻO ka hopena, kūpono loa ia no ka hana lōʻihi i nā lumi lako kelepona paʻakikī a i ʻole nā ​​​​​​wahi waho ʻino.

I loko o nā hoʻolālā pūnaewele optical, hana nā kānana DWDM passive ma ke ʻano he "mea hoʻokele kaʻa." Ke hahai pono nei lākou i nā kūlana o ka International Telecommunication Union (ITU-T), e puʻunaue ana i ka puka makani hoʻoili optical low-loss i nā ʻumi a i ʻole nā ​​​​haneli o nā kahawai kamaʻilio kūʻokoʻa me ka mamao o ka nalu haiki loa.

ʻO ke ʻano kēia, hiki i kahi fiber optical hoʻokahi, i hiki ke lawe i hoʻokahi hōʻailona wale nō, ke hoʻonui koke i kona hiki ke hoʻoili i nā manawa he nui, e hoʻomaikaʻi nui ana i ka pono spectral.

II. Nā hiʻohiʻona noi maʻamau a me ka waiwai

DWDM Passive, OSP Ring OADM, 1 Channel, 100 GHz Spacing, Ch52, Monitor (1%), 900um 1m Fiber, Me ka ʻole o ka mea hoʻohui

Hoʻolālā pinepine ʻia kēia mau kānana passive me nā ʻano hoʻopili maʻamau, e like me nā modula cassette LGX a i ʻole nā ​​​​kāleka rack-mount 19-'īniha, a ua lako me nā mea hoʻohui fiber optic kiʻekiʻe no ka hoʻohui maʻalahi ʻana i nā pūnaewele fiber mode hoʻokahi. ʻO kā lākou mau waiwai noi nui:

Hoʻonui ʻia ʻana o ka Metropolitan Transmission a me ka Backbone Network

Me ka hoʻohui ʻole ʻana i nā kaula fiber kino hou, hiki i ka ʻenehana WDM ke hoʻonui koke i ka bandwidth transmission o nā pūnaewele wahi metropolitan a me nā pūnaewele iwi kuamoʻo ʻāpana, e hoʻokō ana i nā koi nui o ka throughput data o nā lawelawe e like me ke kahe wikiō wehewehe kiʻekiʻe a me ka computing ao.

Nā Pūnaewele Hana Ma waho (OSP) a me ke Komo ʻana

Mahalo i ko lākou mau ʻano passive a me ka mālama ʻole ʻia, ua hoʻolaha nui ʻia kēia mau mea hana i nā pūnaewele hoʻolaha optical waho, e hōʻemi pono ana i nā kumukūʻai hana a me ka mālama lōʻihi no nā mea lawelawe telecom.

Hoʻohui kikowaena ʻikepili

I loko o nā kikowaena ʻikepili a i ʻole ma waena o nā kikowaena ʻikepili he nui, hiki i nā kānana passive ke hoʻokele pono i nā hōʻailona optical he nui me ka pohō hoʻokomo haʻahaʻa loa, e hōʻoiaʻiʻo ana i ka hoʻoili ʻikepili wikiwiki a paʻa.
