Multiplexers SDH: whakaahuatanga, ti'araa

E ngā multiplexers mamati whakaaro arorau e kua hangaia mo te tuku te mana o te mōhiohio i ngā pūtake raraunga maha ki te hongere putanga kotahi. I roto i te meka, he pūrere taua ko te whakakā tū mamati maha. Fakatatau ki ai, Ka taea te faaoti i te reira e te multiplexer mamati ko te tohu pana tāuru ki te raina putanga kotahi. Ka kia whakaaro tenei tuhinga he momo motuhake o ngā pūrere - multiplexers optical SDH.

E hangaia taua whakaaro ki te mahi ki te rere raraunga i te tikanga o kurupae marama, e rerekē i roto i te wāhanga tīwera ranei pae kupenga , me te roangaru. multiplexers SDH tuku mōhiohio i runga i te awa E1 me ngā rārangi Itarangi ki te kawe whatunga muka-whatu. mahi ratou i runga i tetahi e rua ranei optical muka (kotahi-aratau multimode ranei) i 155, 520 Mbit / s i te roangaru o 1550/1310 nm. Ka taea e multiplexers SDH ite ake ki 126 ngā o whakapā.

Ko te painga o taua whakaaro ngā resilience, haumaru hangarau, tiaki ki hacking o ngā mōhiohio tuku.

E ngāwari tauineine ki ngā te wae matua ki runga ki te toru atu takere Itarangi tuku SDH-multiplexers kōwae E1, tukunga kōrero, me te awa o PM.

Kei te āhuatanga e tiketike "kaha i" whatunga ēnei whakaaro. Whakatinanatanga E1 He uara jitter iti kitea e tenei paerewa mō te E1 i roto i tukutahitanga tere, me te kore i STM-1 wā pūnaha. tawhā Atanga tukua ki te aroturuki i te hapa i roto i te hongere kōrero , ka mahi whakawhitinga ki te teihana kē. i whakatoea ara whatu me te mana 1 + 1. Ko, ka mahi i runga i te whatu hongere muka, i roto i te take o te kino o te taura, te hononga rongoa i waenganui i nga kaiohauru te.

multiplexers SDH ngāwari ngā ki ētahi atu momo o te taputapu SDH. Ka taea e ratou te mahi i roto i aratau tukutahinga me tukutahingakore e whakaaetia i roto i te multimode me-aratau kotahi muka. tautoko SDH multiplexer whirihoranga mamao, me te whakahaere o TCP / IP, 10/100 BaseT kawa.

Kei te tikanga wehea pūrere whakawhiti pērā ki e rua ngā momo: kāpeka me ahau / O. E kore te mea te rerekētanga i waenganui i enei momo i te wahi o nga tauranga, a i roto i te whakanohonga o te pūrere i roto i te whatunga SDH. multiplexer Kāpeka whakaoti töpü takere commuting he maha nui o awa putanga me te wāhi i roto ia ratou. Ko te momo tuarua o mea tauwhiro whakawhiti raina whakahiato i runga i te raina e noho i te tūranga takawaenga. Ko te kupu te takere takoha mōhiohio i takea mai i te awa whakahiato patia ranei ki reira.

hua te nuinga o ngā kaiwhakanao momo ao multiplexers SDH, e kua whakamahia rite tāuru / putanga kāpeka, me te whakawhiti-tūhono - i runga i te kōwae tāutatia i roto i to ratou töpü me tauranga takoha rānei.

I roto i te mutunga, tāpiri tatou e multiplexers muka whatu, kei te whiwhi atu me te ake rongonui tika ki te whanaketanga kaha o tenei momo o te kōrero. hoki hangarau muka whatu o te heke mai.
