I-Ethernet ubuchwepheshe benethiwekhi yendawo yekhompyutha, obusetshenziswa kakhulu ukuxhuma amasistimu amaningi enethiwekhi ukuze kuzuzwe inethiwekhi yendawo (LAN). Kunezinhlobo eziningi ze-Ethernet emakethe, okuyi-Ethernet esheshayo ne-Gigabit Ethernet ezivame kakhulu. I-Fast Ethernet (FS) izokunikeza ukuqhathanisa okuningiliziwe kwe-Ethernet esheshayo ne-Gigabit Ethernet ukuze uhlukanise umehluko phakathi kwakho kokubili.
Iyini i-Fast Ethernet?
I-Fast Ethernet (FE) igama le-Ethernet kunethiwekhi yekhompyutha, ehlinzeka ngezinga lokudlulisa elingu-100Mbps. Izinga le-IEEE 802.3u 100BASE-T Fast Ethernet yethulwa ngokusemthethweni yi-IEEE ngo-1995, futhi izinga lokudluliswa kwe-Ethernet esheshayo ngaphambili lalingu-10Mbps. Izinga le-Fast Ethernet lihlanganisa izigaba ezingaphansi ezintathu: 100BASE-FX, 100BASE-TX, kanye ne-100BASE-T4. I-100 ikhombisa izinga lokudlulisela lika-100Mbit/s. "BASE" kusho ukudluliswa kwe-baseband; Uhlamvu olulandela udeshi lubhekisela endaweni yokudlulisela ephethe isignali, "T" imele ipheya esontekile (ithusi), "F" imele i-optical fiber; Uhlamvu lokugcina (uhlamvu "X", inombolo "4", njll.) lubhekisela endleleni yekhodi yomugqa esetshenzisiwe. Ithebula elilandelayo libonisa izinhlobo ze-Ethernet ezisheshayo ezivamile.
Iyini i-Gigabit Ethernet?
Uma kuqhathaniswa ne-Ethernet esheshayo, i-Gigabit Ethernet (GE) inganikeza izinga lokudlulisa elingu-1000Mbps kunethiwekhi yekhompyutha. Izinga le-Gigabit Ethernet (elaziwa ngokuthi yi-IEEE 802.3ab standard) lashicilelwa ngokusemthethweni yi-IEEE ngo-1999, eminyakeni embalwa nje ngemva kokuvela kwezinga le-Fast Ethernet, kodwa alizange lisetshenziswe kabanzi kwaze kwaba ngu-2010. I-Gigabit Ethernet isebenzisa ifomethi yohlaka. ye-IEEE 803.2 Ethernet kanye nendlela yokulawula ukufinyelela kwemidiya ye-CSMA/CD, engasebenza ngemodi eyi-duplex enguhhafu kanye ne-duplex egcwele. I-Gigabit Ethernet inezintambo namadivayisi afanayo ku-Fast Ethernet, kodwa iguquguquka kakhulu futhi iyonga. Ngokuthuthukiswa okuqhubekayo kwe-Gigabit Ethernet, izinguqulo ezithuthuke kakhulu ziye zavela, njenge-40G Ethernet ne-100G Ethernet. I-Gigabit Ethernet inamazinga ahlukene wesendlalelo somzimba, njenge-1000BASE-X, 1000BASE-T, kanye ne-1000BASE-CX.
Okungenhla kunjaloi isingeniso esifushane se-Gigabit Ethernet ne-Ethernet esheshayo elethwe kuwe ngabakwaShenzhenI-HDV I-Photoelectron Ubuchwepheshe LTD futhi SHhenzhenI-HDV I-Photoelectron I-Technology LTD yinkampani egxile ekuxhumaneni kwe-optical njengemishini yokukhiqiza eyinhloko, ukukhiqizwa kwenkampani:I-ONU uchungechunge, uchungechunge lwamamojula optical,OLT uchungechunge, uchungechunge lwe-transceiver luwuchungechunge olushisayo lwemikhiqizo.
Ukwethulwa kuka-OumbonoFiberFerrule
Iningi lemicu ye-optical esivame ukuyibona i-optical fiber jumpers, okungukuthi, zombili iziphetho zinezixhumi, ezingafakwa ngokuqondile futhi zisuswe ngaphandle kokusebenzisa amanye amathuluzi, okuthiwa isixhumi sibhekisela ku-SC, FC, LC nezinye izinhlobo zokuhlukaniswa. .
Futhi uyini umgogodla, njengoba igama lisho ukuthi ingafakwa futhi ikhishwe ngaphandle kwengqikithi, ngokuvamile eyenziwe nge-ceramic, ingqikithi ngokuvamile ngesikhathi esifanayo nesixhumi, noma uma sikhuluma kabanzi, ingqikithi ilingana nesixhumi. , ithini indaba eqondile? Ake ngikutshele lokhu kancane.
Umnyombo ongaphakathi kwefayibha engenalutho empeleni mncane kakhulu futhi kulula ukuphuka, ngakho kukhona okudingayo ukuwuvikela. Phakathi nendawo ye-fiber, sizobeka i-cladding ukumboza umgogodla ukuze udlale indima yokuzivikela, bese kuthi ngomsila we-fiber sisebenzisa i-ceramic core. Kukhona imbobo encane kakhulu phakathi nendawo, inkaba ibhobozwa ngale mbobo engxenyeni yensimbi bese iphuma engxenyeni ye-ceramic, ingxenye eyengeziwe inqunywe ohlangothini lwe-ceramic, bese uthatha ithuluzi ukuze ugaye. ingxenye eyengeziwe isicaba, futhi qaphela lapho ugaya, amandla amaningi azophinde aphule umongo ngaphakathi komgogodla. (U-Xiabian ukhumbule ukuthi umgogodla wangaphakathi wagawulwa ngesandla ngesikhathi sokuhlolwa kwenyuvesi. Lapho ukukhanya kudluliselwa, kutholakala ukuthi ikhanda lepulaki likhipha ukukhanya okubomvu okusobala, kodwa amandla okuhlola awaphezulu, ngoba ukukhanya akusekho. isakazwa ngomugqa oqondile, kodwa ihlakazekile, okuholela ekukhanyeni okuphansi kakhulu okukalwa ngezinombolo ndawonye, hhayi kuphela ukuxhumana okuqinile, kodwa futhi ukuvimbela ukuchichima ukukhanya Yiqiniso, insimbi ewumgogodla ayixhunywanga ku-fiber optical, ingase isetshenziselwe ukukhiqizwa kwe-BOSA.
I-ShenzhenI-HDV I-Photoelectron UbuchwephesheLTD. ikulethela incazelo ye-"optical fiber plug", futhi inkampani yethu ingumkhiqizi wemishini yokuxhumana optical ochwepheshe, imikhiqizo eyinhloko ihlanganisa okuningi. kunaI-ONU uchungechunge,OLT uchungechunge, uchungechunge lwamamojula optical, uchungechunge lwe-transceiver nokunye. Izinto zokusebenza ezingenhla zinezincazelo ezihlukahlukene namamodeli ukuze zinikeze izinsizakalo eziqondiwe ezimweni ezihlukene zesidingo senethiwekhi, wamukelekile ukufika kwakho.
