Ethernet ni mudasobwa yaho ikorana buhanga rya tekinoroji, ikoreshwa cyane cyane muguhuza sisitemu nyinshi kugirango ugere kumurongo waho (LAN). Hariho ubwoko bwinshi bwa Ethernet kumasoko, muribwo Ethernet yihuta na Gigabit Ethernet nibisanzwe. Ethernet yihuta (FS) izaguha igereranya rirambuye rya Ethernet yihuse na Gigabit Ethernet kugirango utandukanye itandukaniro ryombi.
Ethernet yihuta ni iki?
Ethernet yihuta (FE) nijambo rya Ethernet muguhuza mudasobwa, itanga igipimo cyo kohereza 100Mbps. IEEE 802.3u 100BASE-T Byihuta Ethernet yashyizweho na IEEE kumugaragaro mu 1995, kandi umuvuduko wa Ethernet wihuta wari 10Mbps. Igipimo cyihuta cya Ethernet gikubiyemo ibyiciro bitatu: 100BASE-FX, 100BASE-TX, na 100BASE-T4. 100 yerekana igipimo cyo kohereza 100Mbit / s. "BASE" bisobanura kohereza baseband; Inyuguti nyuma yumurongo werekana uburyo bwo kohereza butwara ibimenyetso, "T" bisobanura guhuza (umuringa), "F" bisobanura fibre optique; Inyuguti ya nyuma (inyuguti "X", umubare "4", nibindi) bivuga uburyo bw'imirongo ikoreshwa. Imbonerahamwe ikurikira irerekana ubwoko bwihuse bwa Ethernet.
Gigabit Ethernet ni iki?
Ugereranije na Ethernet yihuta, Gigabit Ethernet (GE) irashobora gutanga igipimo cyo kohereza 1000Mbps mumurongo wa mudasobwa. Igipimo cya Ethernet ya Gigabit (kizwi ku izina rya IEEE 802.3ab) cyasohowe ku mugaragaro na IEEE mu 1999, nyuma yimyaka mike nyuma y’igipimo cyihuta cya Ethernet, ariko nticyakoreshejwe cyane kugeza mu mwaka wa 2010. Gigabit Ethernet yakoresheje imiterere yikadiri. ya IEEE 803.2 Ethernet hamwe na CSMA / CD itangazamakuru uburyo bwo kugenzura uburyo, bushobora gukora muri kimwe cya kabiri cya duplex nuburyo bwuzuye bwa duplex. Gigabit Ethernet ifite insinga nibikoresho bisa na Ethernet yihuta, ariko birahinduka kandi byubukungu. Hamwe niterambere rihoraho rya Gigabit Ethernet, hagaragaye izindi verisiyo zateye imbere, nka 40G Ethernet na 100G Ethernet. Gigabit Ethernet ifite ibipimo ngenderwaho bitandukanye, nka 1000BASE-X, 1000BASE-T, na 1000BASE-CX.
Ibyavuzwe haruguru nii kumenyekanisha muri make Gigabit Ethernet na Ethernet yihuse yazanwe na ShenzhenHDV Ifotoon Ikoranabuhanga LTD na SShenzhenHDV Ifotoon Ikoranabuhanga LTD ni isosiyete izobereye mu itumanaho rya optique nkibikoresho nyamukuru bitanga umusaruro, umusaruro w’isosiyete:ONU urukurikirane, optique module ikurikirana,OLT urukurikirane, transceiver urukurikirane nuruhererekane rwibicuruzwa.

Ibyinshi muri fibre optique dusanzwe tubona ni optique ya fibre isimbuka, ni ukuvuga ko impande zombi zifite umuhuza, zishobora kwinjizwamo no gukurwaho udakoresheje ibindi bikoresho, ibyo bita umuhuza bivuga SC, FC, LC nubundi bwoko bwo gutondekanya .
Nibyingenzi niki, nkuko izina risobanura ko rishobora kwinjizwamo no gukururwa hanze, muri rusange ryakozwe muri ceramic, intangiriro muri rusange icyarimwe hamwe nu muhuza, cyangwa nukuvuga muri rusange, intangiriro ihwanye nu muhuza. , nikihe kibazo cyihariye? Reka nkubwire buhoro.
Intangiriro imbere ya fibre yambaye ubusa mubyukuri iroroshye cyane kandi yoroshye kumeneka, kuburyo ikintu gikeneye kukirinda. Hagati ya fibre, tuzashyiraho cladding kugirango dutwikire intangiriro kugirango tugire uruhare mukurinda, hanyuma kumurizo wa fibre dukoresha ceramic core. Hano hari umwobo muto cyane hagati yinturusu, intoki yacengewe muri uyu mwobo mugice cyicyuma hanyuma ikava mubice bya ceramic, igice cyongeweho kicibwa kuruhande rwibumba, hanyuma ugafata igikoresho cyo gusya. igice cyongeweho kiringaniye, kandi witondere mugihe cyo gusya, imbaraga nyinshi nazo zizacika intangiriro imbere. . ikwirakwizwa mu murongo ugororotse, ariko iratatana, bivamo urumuri ruto cyane rwapimwe mu mibare. Impera y'icyuma ni hagati ya fibre optique, ubusanzwe ikingirwa no kwambara no gutwikira hamwe, ntabwo ari uguhuza gukomeye, ariko kandi kugirango wirinde urumuri rwinshi, Birumvikana ko ibyuma byibanze bitagomba guhuzwa na fibre optique, birashobora no gukoreshwa mubikorwa bya BOSA.
ShenzhenHDV Ifotoon IkoranabuhangaLTD. akuzaniye ibisobanuro bya "optique ya fibre optique", kandi isosiyete yacu ni uruganda rukora ibikoresho byitumanaho rukora ibikoresho, ibicuruzwa byingenzi bikubiyemo byinshi kurutaONU urukurikirane,OLT urukurikirane, optique module ikurikirana, transceiver ikurikirana nibindi. Ibikoresho byavuzwe haruguru bifite ibisobanuro bitandukanye hamwe nicyitegererezo cyo gutanga serivise zigenewe ibintu bitandukanye bisabwa nurusobe, ikaze ukuza kwawe.
