Ngā Momo Hononga Muka Whatu

2025-02-12

Me whakamārama e au ngā momo hononga muka whatu rerekē. Kia tīmata māku mā te whakamahara i aku mōhiotanga. Ka whakamahia ngā hononga muka hei hono i ngā muka whatu ina hiahiatia he āheinga hono/momotu. He maha ngā momo, he hoahoa me ngā whakamahinga motuhake tō ia momo.

Tuatahi, ko te hononga ST. E mahara ana ahau he hononga momo bayonet, he rite pea ki ngā mea e whakamahia ana i roto i ngā whatunga tawhito. Kātahi ka tae mai te SC, ki taku whakaaro he hononga snap-in, he āhua tapawhā. He iti ake te LC, he momo pana-tō pea, e whakamahia ana i roto i ngā taiao kiato-teitei. Ka whakamahia e te FC he hononga miro, tika? He haumaru ake, pea mō ngā wāhi wiri-teitei. Ko te MTP me te MPO mō ngā hononga muka-maha, e whakamahia ana i roto i ngā pokapū raraunga. Kei reira anō te MU, he iti ake i te SC, me te E2000 me te kati tiaki. He momo tawhito te SMA, pea mō te whakamahinga ahumahi. Ko te DIN he paerewa Tiamana, he iti ake te kitea. Ā, kei reira ngā hononga takirua pērā i te FDDI me te ESCON, ahakoa kāore au i te tino mōhio mō ēnā.

 

Taria, me tirotiro e au mēnā kei te whakararuraru au i ētahi taipitopito. Hei tauira, he iti te āhua o te LC, he haurua te rahi o te SC. He ingoa waitohu te MTP mō te hononga MPO, tera pea? He rite tonu rānei? Waihoki, ko ētahi hononga he simplex (muka kotahi) me te duplex (muka e rua). Pērā i te LC, ka taea te duplex mā te tapahi i ngā mea e rua. Ka taea hoki te duplex te SC. Ka taea e te MPO/MTP te 12, 24 rānei ngā muka i roto i te hononga kotahi.

Ngā Momo Hononga Muka Whatu Ngā Whakamahinga: He mea noa te ST i ngā whare wānanga, te SC i roto i te whakawhitiwhiti raraunga, te LC i roto i ngā hononga kiato-teitei pēnei i ngā pokapū raraunga, te FC i roto i ngā taputapu, te MPO i roto i ngā hononga tuara. Me kōrero au mō te ngaronga whakaurunga me te ngaronga whakahoki mō ia mea, he mea nui tēnā mō te mahi. Waihoki, ko ngā momo whakakanapa pēnei i te PC, UPC, APC. He koki te APC mō te whakaata o raro o te tuara, e whakamahia ana i roto i ngā whatunga tere-teitei pēnei i te GPON.

 

Taria, i pātai te kaiwhakamahi mō ngā momo hononga, engari ko te whakakanapa i ngā momo he wāhanga o ngā whakaritenga hononga. Me whakauru atu e au tēnā? I whakaurua te whakautu tuatahi, nō reira he pai pea. Tukua ahau kia whakarite i ia hononga me ngā āhuatanga matua, ngā tono noa, me ngā whakaritenga mahi.

Me whakarite kia kore e ngaro i ahau ētahi momo nui. Me whakarārangi anō tātou i ēnei: ​​ST, SC, LC, FC, MTP/MPO, MU, E2000, SMA, DIN, FDDI, ESCON, D4, me ētahi atu pēnei i a Biconic, Opti-Jack rānei? Engari he iti ake te kitea o ēnei. Kia arotahi ki ngā mea matua kua whakahuatia.

 

Me whakaahua hoki ngā āhuatanga ā-tinana mō ia hononga: te momo hononga (bayonet, snap-in, miro), te rahi o te ferrule (he ferrule 2.5mm te ST, SC, LC 1.25mm). He ferrule tapawhā rite te MPO/MTP me ngā muka maha.

 

Ngā Momo Hononga Muka Whatu Ngā Whakamahinga: ST i ngā whatunga tawhito, FC i te waea whakawhitiwhiti, LC i ngā pokapū raraunga hou, MPO i ngā tuara tere-teitei pēnei i te 40/100G Ethernet.

 

Ngā Momo Tūhono Muka Whatu Mahi: Te Ngaronga Whakauru (te nui o te mārama e ngaro ana ina honoa) me te Ngaronga Whakahoki (te Whakaata Whakamuri). He pai ake te ngaronga whakahoki o te APC nā te oro koki.

 

Me mōhio anō hoki ahau he rongonui ake ētahi hononga i ētahi rohe, pērā i te E2000 i Ūropi. Ka whakamahia te SMA i roto i ngā mahi hōia, i ngā mahi ahumahi rānei nā te mea he roa.

 

Tukua ahau kia whakarite i ēnei mōhiohio ki ngā tohu matua mō ia momo hononga, pērā i te whakautu tuatahi. Kia poto te kōrero engari kia kapi i ngā tohu matua. Āta karohia ngā hapa hangarau. Hei tauira, he waitohu motuhake a MTP o te MPO, nō reira he rite tonu engari tera pea he whakapainga a MTP. Engari kia māmā ake ai, whakarōpūhia ngātahi.

 

Ngā Momo Hononga Muka Whatu Tirohia anō ngā rahi o te taura: ST, SC, FC e whakamahi ana i te 2.5mm; LC e whakamahi ana i te 1.25mm. He maha-muka te MPO, nō reira he nui ake te taura.

 

Ngā momo whakakanapa hononga muka whatu: PC (Physical Contact), UPC (Ultra Physical Contact), APC (Angled Physical Contact). He koki 8-tohu te APC. He pai ake te ngaronga whakahoki o te UPC i te PC, he pai ake te APC. Nō reira, kei reira ngā hononga pēnei i te SC/APC, LC/APC rānei, i runga i te tono.

Kua noho te taura muka whatu hei poutokomanawa mō ngā whatunga whakawhitiwhiti kōrero hou, e tautoko ana i te ipurangi tere-nui, te whakawhitiwhiti kōrero, ngā pokapū raraunga, te hanganga 5G, te aunoatanga ahumahi, me ngā tāone atamai. Ki te whakatauritea ki ngā taura parahi tuku iho, ka nui ake te whānui o te hononga o ngā taura muka whatu, ka iti ake te ngaronga tohu, ka roa ake te tawhiti tuku, ā, ka pai ake te ātete ki te pokanoa hikohiko.

Me pēhea te whiriwhiri i te taura muka tika?

I te whakatinanatanga nui o te muka FTTH ki te Kāinga, ngā pokapū raraunga rorohiko AI, te hononga mua 5G, te waea whānui o roto, te whakawhitiwhiti kōrero iti FPV drone me te whakahoutanga o te au ngoikore o te whare puta noa i te ao, kei te raru te muka aratau-kotahi tuku iho G.652D i te ngaronga piko nui me te iti o te wāhi waea, e tino whakawhāiti ana i te tahora o ngā whatunga whakawhitiwhiti kōrero whatu tere-teitei. I hangaia e ITU-T, ko te muka aratau-kotahi piko-kore-aroaro raupapa G.657 he mea hanga motuhake mō ngā kokonga hurihuri whaiti, ngā waea matotoru me ngā āhuatanga paipa moroiti. Ko ngā momo hua matua e toru, ko te muka ātete-piko paerewa G.657.A1, te muka ātete-piko whakarei ake G.657.A2 me te muka kore-piko tino-aroaro G.657.B3, e whakamahi ana i ngā kōtaha tohu whakaata āwhina-awaawa rerekē, ā, e whakaatu ana i ngā rerekētanga kua whakaritea i roto i te radius piko iti rawa, te diameter mara aratau me te mahi whakaiti. Ka hipokina e rātou ngā tono horopaki katoa mai i te waea whare ohanga ki te waea motuhake tino-kikī.
