Ko te100M whatu whatu transceiver(e mohiotia ana ko te kaitahuri whakaahua 100M) he kaitahuri Itarangi tere. He tino hototahi ki te IEEE802.3, IEEE802.3u, me te IEEE802.1d te kaitahuri muka. E tautoko ana i nga momo mahi e toru: te taapiri katoa, te haurua rua, me te urutau.
Gigabit whatu whatu transceiver(e mohiotia ana ko te kaitahuri whakaahua) he Itarangi tere me te tere tuku raraunga o te 1Gbps. Kei te whakamahi tonu i te tikanga mana uru CSMA/CD me te hototahi ki te Itarangi o naianei. Ma te tautoko o te punaha waea, Ka taea te whakapai ake i te tere tere tere me te tiaki i te haumi taketake o nga kaiwhakamahi.
Ko te hangarau whatunga Gigabit te hangarau pai mo nga whatunga hou me te hanga ano. Ahakoa kua pai ake nga whakaritenga o te punaha waea whakauru, he pai mo te whakamahi a nga kaiwhakamahi me nga whakahoutanga a meake nei.
Ko te paerewa o Gigabit Ethernet i hangaia e IEEE 802.3, a e rua nga paerewa waea o 802.3z me 802.3ab. I roto i a raatau, ko te 802.3ab he paerewa waea i runga i te takirua takirua, ma te whakamahi i nga takirua e 4 o te waahanga 5 UTP, a ko te tawhiti nui o te tuku he 100m. A ko te 802.3z he paerewa e pa ana ki te Hongere Fiber, a e toru nga momo pāpāho e whakamahia ana:
a) 1000Base-LX whakatakotoranga: Ko tenei tohu e pa ana ki nga tawhā o te multimode me te muka kotahi-mode e whakamahia ana i tawhiti. I roto ia ratou, ko te tawhiti tuku o te muka aratau maha he 300 (550 mita, a ko te tawhiti tuku o te muka aratau kotahi he 3000 mita.) Ko te whakaritenga me whakamahi i nga kaiwhakawhiti laser ngaru-roa te utu.
b) 1000Base-SX whakatakotoranga: Ko tenei tohu ko nga taapiri o te muka multimode e whakamahia ana i nga tawhiti poto. Ka whakamahi i te muka multimode me te CD ngaru poto iti-utu (kopae kiato) ranei VCSEL lasers, a ko tona tawhiti tuku he 300（550 mita.)
Ko nga korero: Ko te kaitahuri whatu Gigabit he momo kaitahuri tohu tohu e whakamahia ana hei huri i te tohu hiko o te rorohiko Gigabit Ethernet ki te tohu whatu. He rite ki te paerewa IEEE802.3z/AB; ko tona ahuatanga he tauranga hiko Ko te tohu e rite ana ki te 1000Base-T, ka taea te whakarereke i a ia ano ma te raina tika / raina whakawhiti; ka taea hoki i roto i te aratau matarua/hawhe matarua.
I tenei wa, neke atu i te kotahi rau megabits e whakamahia ana, a, he iti noa nga mea kua whakamahia, engari inaianei kua tata haere nga utu mo te kotahi rau megabits me te gigabit. Mena ka titiro koe mai i te tirohanga mo te wa roa, ka tūtohu kia whakamahia te gigabitnga kaiwhakawhitiwhiti muka.
Mena karekau he whakaritenga motuhake a te whatunga o naianei, ahakoa ko te tuku i te ataata whakamarama-nui, te nui ranei o te tuku raraunga, he ranea te whatunga 100M.
100M he iti ake te utu o nga kaiwhakawhiti whatu i te gigabit whatu transceivers, a ka whakamahia ano hoki te 100M whatu transceivers i runga i te utu. Engari, mehemea ko te whatunga rohe o te rohe he whatunga gigabit, he pai ake te whakamahi i nga whakawhiti whakawhiti gigabit i te 100M transceiver.
Whakarāpopototanga: He rite tonu te mahi a nga kaiwhakawhitiwhiti muka tere me te Gigabit, ka whakamahia ki te whiwhi tohu marama, engari he rereke to raatau bandwidth, he tere ake te tere o te Gigabit.
