Pinout kpara akpa ụzọ

Modern ụzọ nke Internet ohere njikọ enye ọtụtụ nhọrọ: eji coaxial USB, eriri optic agbagọ ụzọ. Ka anyị biri na e ji mara nke gburugburu cable na otú pinout ka nke gbagọrọ agbagọ ụzọ, ihe dị mkpa na ihe iwu a ga-agbaso.

Kpara akpa ụzọ a na-akpọ wires na-gbagọrọ na kpuchie mkpuchi. A kpara akpa cable nwere ike nkejikotara abụọ ma ọ bụ anọ kpara akpa na abụọ nke wires, enịm ke a dielectric n'ọbọ. The wires na-na iche iche voltaji ọmụma mgbaàmà ọnọ site ha. ọtụtụ ụdị nke gbagọrọ agbagọ-ụzọ nwere ike mata. Ha na-unshielded, foil na mpụga ihuenyo, foil na a ụzọ mpụga meziri, na-echebe na echebekwa echebe. Kpara akpa ụzọ nwere otu mwepu. Mgbe ya na ime e nwere ihe ize ndụ nke interception nke ozi-ebute site ná site na USB. Izere ọ dị mkpa iji zere eavesdropping. N'aka nke ọzọ Ọgba Gịnị bụ nnọọ oké ọnụ, ya mere na-adịkarịghị eji.

The Gịnị, nke na-eji kpara akpa na ụzọ, ekewa n'ime ọtụtụ ige. Nke mbụ bụ na ekwentị USB ebute okwu. Site na udi cable 2 nwere ike ebunye ọmụma na a ugboro ole gbalaga ruo otu megahertz, Category 3 - iri na isii megahertz, Atiya 4 - iri abụọ megahertz. Ikpeazụ ya na-adịkarịghị eji, n'ihi na ọ fọrọ nke nta mba dị iche iche si cable 3 ige.

The kasị zuru okè na oge a na-ewere nke ise, Atiya USB, haziri maka nnyefe nke ozi ke frequencies nke ruo otu narị megahertz. Kpara akpa ụzọ Atiya 5 bụ ihe na-erughị iri abụọ na asaa, ibe kwa mita nke ogologo. Na-emekarị, e nwere ọtụtụ iberibe, iri abụọ na ise na abụọ. The cable adabara ejikọta kọmputa na Internet na e kere eke nke na mpaghara na netwọk. E nwere Gịnị 6 na nke 7 na edemede, nke na-karị gbakọọ maka 200 na 600 megahertz. Category 6 cable na-eji jikọọ Ethernet netwọk.

Mgbe ejikọta na mpaghara na netwọk na ihe abụọ kọmputa nwere ihe isi ike. Iji merie ha ma na-eme ihe ndị kasị ezigbo njikọ, na-achọ na netwọk kaadị kọmputa agbagọ ụzọ, na-ezo aka ise, Atiya, nakwa dị ka Njikọ bụ RJ-45.

Ebe ọ bụ na cables esịnede kpara akpa ụzọ abụọ, ndị siri ike bee n'ime mgbidi tinyekwa, ọ na-ewe ha crimp, nke a rụrụ dị ka ụkpụrụ na ojiji nke pụrụ iche ngwaọrụ-adịghị emetụta àgwà nke data nnyefe. Ọ bụrụ na USB nwere asatọ-eduzi, na-enwe pinout gbagọrọ ụzọ Ethernet na Gigabit Ethernet ụkpụrụ. N'ihi na eziokwu na cables bụ Atiya 5 na nke 6 na-egosi nke ọma na ya onwe ya na torsion na-ekwe, ha na-ọma na-eji maka n'ichepụta nke kwachie udọ na jikọọ na mpụta outlets.

Birinụ abụọ embodiments, nke na-eji na njikọ kọmputa na netwọk ma ọ bụ jikọọ a PC na netwọk ngwaike (udọ). Ọzọkwa, dum na mpaghara na netwọk nwere ike iji naanị otu version, nke ga-ẹkenịmde na kpara akpa-ụzọ pinout. The cable ga-kwadebere maka ntinye n'ime njikọ. Ọ bụ uru na-arịba ama na ma ndị RJ-45 njikọ ga-crimped dokwara. E nwere ihe abụọ na ụdị crimping, nke na-etinyere na kpara akpa ụzọ. The mbụ (na-atụ iji) nwere ntụziaka "workstation Hub". The abụọ - n'obe, cross-Linkova.

Iji jikọọ ozugbo na netwọk kaadị nke abụọ kọmputa, mkpa ka ị na itughari USB nke mere na ụzọ (atụ, oroma na green) nwesịrị. N'ihi ya pinout ẹkenịmde kpara akpa ụzọ USB, dị ka a n'ihi nke a otu n'ime njikọta ka crimped mbụ n'onwe, na nke abụọ - na abụọ. The cable ga-ahụ ga na-akpọ a crossover. Na-akpọ nulhabnym.

N'ihi ya, uru nke gbagọrọ agbagọ ụzọ abụọ a na-ewere dị ka udo nke echichi na ala na-eri. Tọrọ atọ ruo ọtụtụ eduzi nwere a ukwuu mgbaàmà attenuation na kasị jikọọ na Ịntanetị, iji melite ogo nke usoro eji pinout gbagọrọ ụzọ cable na-enye ohere ka imeghari ka ogige na a na kọmputa na peripherals.
