Ko te muka aratau kotahi, me te multimode pērā

A, no te haere mai te reira ki te tuku raraunga i tetahi wāhi mamao ki tetahi, te whakanui ake hei utu o te waea parahi tuku iho ki nga kirimana kiritaki karangatia ki whakapanga te taura whatu. Mō tenei hangarau whakaongaonga i tenei ra matou me ka kōrero tatou.

aho kōrero muka-whatu (muimui) mahi i runga i te parau tumu o te tuku o ngaru marama e takere motuhake hanga o te karaihe kiripaka tino parakore. ponana Electrical o taputapu hiko whakaratohia ki te kaitahuri tohu, e mahia he awa o ngātere marama, me te whakawhiti ratou ki te taura. I te tahi atu pito o te kaiwhiwhi marama e tango te awa, me te transcodes reira whakahokia ki te ngātere hiko. No te mea kei te rorohiko whakahaeretia te tukanga katoa, me te ko te faafariuraa mamati, distortion iti.

Hei hanga i taua pūtāuta, te whakamahi i te rauemi motuhake - muka-aratau kotahi, me te multimode.

i pera whānui Optic rārangi, e kore anake e tika ana ki te kore o pokanoa ki te tuku o te tohu. I roto i nga painga mâro-o tenei hangarau ko te ropu whanui, he attenuation tohu rawa ngoikore, ātete kē ki tetahi pokanoa o te natura hiko, te whānuitanga tuku nui, i te tokomaha kia tekau o kiromita. He painga nui ko te mahi kōrero wā roa, whakatakotoria te whakamahi i te te pūtāuta, kia i te iti rawa 25 tau.

momo o te muka

A, no te whakapuru hononga te whakamahi i te rārangi muka-whatu tīpakohia te multimode ranei ranei muka aratau kotahi.

He aha te mea tenei taura? Ko te matua o te muka, ko te kiripaka, ultrapure karaihe, e haere hoki i roto i te kurupae marama. He riringi e kore e puta i te reira no te mea te taupū anga hakoko raro atu i te matua, na reira, kei te rawa kitea te kurupae marama i te taiepa i roto i te muka.

Multimode pai kia taea rere reira e rave rahi rau aratau marama e kua whakaurua i koki rerekē. aratau Ia he ona ake ara, me te, rite te putanga, te wa whakatö ahurei.

Ko te drawback matua o tenei momo o te muka - aratau purara, e iti mai te hōkaiipurangi me tauwhāiti te roa raina mōrahi. Foaki mo multimode raina kōrero e te nuinga o te tawhiti mōrahi o e pā ana ki 5 kiromita.

Ko te raruraru o te whakaiti aratau manene whakatau taura ki te rōnaki kōtaha te taupū hakoko o te matua. Tenei muka, i roto i te rerekē ki paerewa taupū kōwhiringa kōwhiringa hakoko heke i te matua pokapū ki te anga, e homai whakapai ake nui i roto i te tawhā o te tohu tuku.

hangaia te muka aratau kotahi, e hāngai ana i runga i te mahi e tika ana i te hongere kōrero kotahi anake aratau (taketake). He maha ngā painga tenei huarahi. Ētahi āhuatanga i roto i te taura, i hanga o te hangarau-aratau kotahi, he tikanga o te nui pai atu i taua whakaputaina e te multimode. Ko te take whakatakotoria e pā te kōwhiringa i roto i te manakohia o te Engineers tuatahi i roto i te whakapanga hononga muka whatu hou tenei. Ko e mo'oni, whakarato muka-aratau kotahi attenuation i 0,25db ia kiromita, he iti rawa te rerekētanga o reira, me te whakarato hōkaiipurangi whanui he tuku mārama, me te tere o te nui o ngā raraunga kahore distortion.

Ko reira kei roto i te rango hinu i roto i te hinu. Ko nui atu te utu atu i te muka multimode tenei momo. Mai te mea iti rawa te rahi o nga otaota marama-ārahi i roto i te-taura kotahi, te tāuru radiation i roto i te taura taua he wero, me te titau mana rawa tupato i roto i te splicing. Ko te tūhono mutunga mo enei raina me te he nui atu te utu atu i ngā rārangi kontseviki multimode. I tua atu, ko te whakamutunga e tika ana ki te tapatahi o te tāuru kurupae marama ki te matua whānui o tino māmā, ongoi e cheap, i hua hoki he maha nui o whakataetae kamupene.
