N'oge mgbawa ozi, ihe fọrọ nke nta ka ọ bụrụ onye ọ bụla kwesịrị ịnweta ịntanetị, na ihe fọrọ nke nta ka ọ bụrụ ebe ọ bụla nwere netwọk na netwọk netwọk, ma ị nwere ike ọ gaghị ama na ọ bụ ezie na eriri netwọk na-ele anya otu ihe, e nwere n'ezie ụdị dị iche iche. N'ebe a, isiokwu a ga-atụnyere eriri netwọk Cat5e (super 5), eriri netwọk Cat6 (6), eriri netwọk Cat6a (super 6) na eriri netwọk Cat7 (7), iji nyere gị aka ịhọrọ eriri netwọk ziri ezi.
A na-akpọkwa eriri netwọk dị ka jumper netwọk na ụzọ gbagọrọ agbagọ, a na-ejikarị ya na isi RJ 45 kristal, n'ihi na ọ dị ọnụ ala ma na-ejikarị ya na LAN, na eriri netwọk bụ usoro mgbasa ozi na-emekarị na wiring agbakwunyere.
Cat5e na-arụ ọrụ n'otu ụzọ ahụ dị ka eriri netwọk Cat6, ha abụọ nwere otu ụdị nkwụnye RJ-45, ma nwee ike itinye ya na jakị Ethernet ọ bụla na kọmputa,rawụta, ma ọ bụ ngwaọrụ ndị ọzọ yiri ya. Ọ bụ ezie na ha nwere ọtụtụ myirịta, ha nwere ụfọdụ ọdịiche, Cat5e netwọk USB etinyere na Gigabit Ethernet, nnyefe anya ruo 100m, na ike na-akwado 1000Mbps nnyefe ọsọ. Igwe netwọkụ Cat6 nwere ike ịnye ọsọ nnyefe ruru 10 Gbps na bandwit 250 MHz. Ogologo nnyefe nke eriri netwọk Cat5e na eriri netwọk Cat6 bụ 100m, ma mgbe ị na-eji ngwa GBASE-T 10, ebe nnyefe nke eriri netwọk Cat6 nwere ike iru 55 m. Isi ihe dị iche n'etiti Cat5e na Cat6 bụ arụmọrụ njem. Igwe Cat6 nwere ihe nkesa dị n'ime nke na-ebelata nnyonye anya ma ọ bụ crosstalk proximal (NEXT). Ọ na-emeziwanye crosstalk distal (ELFEXT) karịa eriri Cat5e, ma nwee mfu nhụsianya dị ala na mfu ntinye. Yabụ, eriri Cat6 nwere arụmọrụ ka mma. Igwe netwọk Cat6 na-akwado nnyefe ọsọ ruo 10G ma nwee bandwidth ugboro ugboro ruo 250 MHz, ebe eriri netwọk Cat6a nwere ike ịkwado bandwidth ugboro ugboro ruo 500 MHz, ugboro abụọ nke eriri netwọk Cat6. Igwe netwọkụ Cat7 na-akwado bandwit ugboro ole ruru 600 MHz, ma na-akwado 10 GBASE-T Ethernet. Na mgbakwunye, eriri netwọk Cat7 na-ebelata mkpọtụ crosstalk nke ukwuu ma e jiri ya tụnyere eriri netwọk Cat6 na Cat6a. Cat5e Network cable, Cat6 USB na Cat6a cable nwere njikọ RJ 45, ma njikọ nke Cat7 cable bụ ihe pụrụ iche, ụdị njikọ ya bụ GigaGate45 (CG45). Ka ọ dị ugbu a, ụkpụrụ TIA / EIA akwadola eriri Cat6 na eriri Cat6a, mana eriri Cat7 adịghị.
Igwe netwọkụ Cat6 na eriri netwọk Cat6a dabara adaba maka iji ụlọ. Kama, ọ bụrụ na ị na-agba ọsọ ọtụtụ ngwa, ị kwesịrị ị na-ahọrọ nke ọma Cat7 netwọk USB, n'ihi na ọ bụghị nanị na-akwado otutu ngwa, ma na-enwekwa mma arụmọrụ.
