Ethernet ndiukadaulo wamakompyuta amdera lanu, womwe umagwiritsidwa ntchito makamaka kulumikiza ma netiweki angapo kuti akwaniritse netiweki yapafupi (LAN). Pali mitundu yambiri ya Efaneti pamsika, yomwe mwachangu Efaneti ndi Gigabit Efaneti ndizofala kwambiri. Fast Ethernet (FS) ikupatsani kufananitsa kwatsatanetsatane kwa Efaneti wachangu ndi Gigabit Efaneti kuti musiyanitse kusiyana pakati pa ziwirizi.
Kodi Fast Ethernet ndi chiyani?
Fast Ethernet (FE) ndi mawu oti Ethernet pamanetiweki apakompyuta, omwe amapereka kusamutsa kwa 100Mbps. Muyezo wa IEEE 802.3u 100BASE-T Fast Ethernet udayambitsidwa ndi IEEE mu 1995, ndipo kufalikira kwa Ethernet mwachangu kale kunali 10Mbps. Muyezo wa Fast Ethernet umaphatikizapo magawo atatu: 100BASE-FX, 100BASE-TX, ndi 100BASE-T4. 100 ikuwonetsa kufalikira kwa 100Mbit / s. "BASE" amatanthauza kutumiza kwa bandeji; Kalata ikadutsa pamzerewu imatanthawuza njira yotumizira chizindikiro, "T" imayimira awiri opindika (mkuwa), "F" imayimira nsonga ya kuwala; Chilembo chomaliza (chilembo "X", nambala "4", ndi zina zotero) chimatanthawuza njira ya mzere wogwiritsidwa ntchito. Gome lotsatirali likuwonetsa mitundu yodziwika bwino ya Efaneti.
Kodi Gigabit Ethernet ndi chiyani?
Poyerekeza ndi Efaneti wachangu, Gigabit Efaneti (GE) ikhoza kupereka kutengerapo kwa 1000Mbps pamaneti apakompyuta. Muyezo wa Gigabit Efaneti (wotchedwa IEEE 802.3ab standard) unasindikizidwa mwalamulo ndi IEEE mu 1999, patangopita zaka zochepa kuchokera pakubwera kwa Fast Ethernet muyezo, koma sunagwiritsidwe ntchito kwambiri mpaka cha 2010. Gigabit Efaneti akutenga mawonekedwe a chimango. ya IEEE 803.2 Efaneti ndi njira ya CSMA/CD media access control, yomwe imatha kugwira ntchito mu theka la duplex ndi duplex mode. Gigabit Ethernet ili ndi zingwe ndi zida zofanana ndi Fast Ethernet, koma ndizosunthika komanso zotsika mtengo. Ndi chitukuko chokhazikika cha Gigabit Ethernet, matembenuzidwe apamwamba kwambiri awonekera, monga 40G Ethernet ndi 100G Ethernet. Gigabit Ethernet ili ndi magawo osiyanasiyana osanjikiza thupi, monga 1000BASE-X, 1000BASE-T, ndi 1000BASE-CX.
Pamwambapa ndindi Kufotokozera mwachidule kwa Gigabit Efaneti ndi Efaneti yachangu yobweretsedwa ndi ShenzhenZithunzi za HDV Photoelectron Malingaliro a kampani Technology LTD ndi SHhenzhenZithunzi za HDV Photoelectron Technology LTD ndi kampani okhazikika mu kuwala kulankhulana monga zida zazikulu zopangira, kampaniyo kupanga:ONU mndandanda, optical module series,OLT mndandanda, transceiver mndandanda ndi otentha mndandanda wa zinthu.
Chiyambi cha OpticalFiberFerrule
Ulusi wambiri wa kuwala womwe timawona nthawi zambiri ndi optical fiber jumpers, ndiko kuti, mbali zonse ziwiri zimakhala ndi zolumikizira, zomwe zimatha kulowetsedwa mwachindunji ndikuchotsedwa popanda kugwiritsa ntchito zida zina, cholumikizira chotchedwa SC, FC, LC ndi mitundu ina yamagulu. .
Ndipo pachimake ndi chiyani, monga momwe dzinalo limatanthawuzira kuti chitha kulowetsedwa ndikuchichotsa pachimake, chomwe chimapangidwa ndi ceramic, pachimake nthawi zambiri chimakhala cholumikizira, kapena kunena momveka bwino, pachimake chimakhala chofanana ndi cholumikizira. , nkhani yeniyeni ndi chiyani? Ndiroleni ndikuuzeni izi pang'onopang'ono.
Pakatikati mwa ulusi wopanda kanthu ndi woonda kwambiri komanso wosavuta kusweka, ndiye kuti pali chinthu chofunikira kuuteteza. Pakatikati mwa ulusi, tidzayika chotchinga kuti chiphimbe pachimake kuti chiteteze, ndiye kuti mchira wa ulusi timagwiritsa ntchito pachimake cha ceramic. Pali dzenje laling'ono kwambiri pakati pa pachimake, pachimake amabowoledwa kudzera mu dzenje ili mu gawo lachitsulo ndiyeno kuchokera ku gawo la ceramic, gawo lowonjezera limadulidwa kuchokera kumbali ya ceramic, ndiyeno mutenge chida chopera. gawo lowonjezera lathyathyathya, ndipo samalani popera, mphamvu yochuluka idzaphwanyanso pakati pakatikati. (Xiabian kumbukirani kuti pachimake mkati anali pansi pa dzanja pa kuyesera yunivesite. Pamene kuwala ndi opatsirana, amapezeka kuti pulagi mutu umatulutsa kuwala kofiira, koma mayeso mphamvu si mkulu, chifukwa kuwala sikulinso. zimafalitsidwa mumzere wowongoka, koma zimamwazikana, zomwe zimapangitsa kuti pakhale kuwala kochepa kwambiri komwe kumayesedwa ndi nambala pamodzi, osati kugwirizana olimba, komanso kuteteza kuwala kusefukira, ndithudi, pachimake zitsulo si ogwirizana CHIKWANGWANI kuwala, angagwiritsidwenso ntchito BOSA kupanga.
ShenzhenZithunzi za HDV Photoelectron ZamakonoLTD. imakubweretserani kufotokozera kwa "optical fiber plug", ndipo kampani yathu ndi akatswiri opanga zida zoyankhulirana, zinthu zazikulu zimaphimba zambiri. kuposaONU mndandanda,OLT series, optical module series, transceiver series ndi zina zotero. Zida zomwe zili pamwambazi zili ndi mitundu yosiyanasiyana komanso zitsanzo kuti zipereke ntchito zomwe zikuyembekezeredwa pazovuta zosiyanasiyana zapaintaneti, landirani kubwera kwanu.
