Ethernet yog lub khoos phis tawj hauv cheeb tsam hauv cheeb tsam network thev naus laus zis, uas yog siv los txuas ntau lub network kom ua tiav thaj chaw hauv cheeb tsam (LAN). Muaj ntau hom Ethernet nyob rau hauv kev ua lag luam, uas ceev Ethernet thiab Gigabit Ethernet yog qhov feem ntau. Fast Ethernet (FS) yuav muab cov ncauj lus kom ntxaws sib piv ntawm ceev Ethernet thiab Gigabit Ethernet kom paub qhov txawv ntawm ob.
Fast Ethernet yog dab tsi?
Fast Ethernet (FE) yog lo lus rau Ethernet hauv kev sib txuas hauv computer, uas muab kev hloov pauv ntawm 100Mbps. Tus qauv IEEE 802.3u 100BASE-T Fast Ethernet tus qauv tau tshaj tawm los ntawm IEEE hauv xyoo 1995, thiab tus nqi xa mus ceev Ethernet yav dhau los yog 10Mbps. Tus txheej txheem ceev Ethernet suav nrog peb pawg: 100BASE-FX, 100BASE-TX, thiab 100BASE-T4. 100 qhia qhov kis tus nqi ntawm 100Mbit / s. "BASE" txhais tau tias kev sib kis ntawm baseband; Tsab ntawv tom qab qhov khiav ceev yog hais txog qhov nruab nrab kis tau tus mob nqa lub teeb liab, "T" stands rau twisted khub (tooj liab), "F" stands rau optical fiber; Cov cim kawg (tus ntawv "X", tus lej "4", thiab lwm yam) yog hais txog cov kab code siv. Cov lus hauv qab no qhia txog hom Ethernet ceev ceev.
Gigabit Ethernet yog dab tsi?
Piv rau ceev Ethernet, Gigabit Ethernet (GE) tuaj yeem muab kev hloov pauv ntawm 1000Mbps hauv lub computer network. Gigabit Ethernet tus qauv (lub npe hu ua IEEE 802.3ab tus qauv) tau tshaj tawm los ntawm IEEE hauv xyoo 1999, tsuas yog ob peb xyoos tom qab qhov kev tshwm sim ntawm tus qauv Fast Ethernet, tab sis nws tsis tau siv dav mus txog rau xyoo 2010. Gigabit Ethernet tau txais cov qauv qauv. ntawm IEEE 803.2 Ethernet thiab CSMA / CD media access control method, uas tuaj yeem ua haujlwm hauv ib nrab duplex thiab puv duplex hom. Gigabit Ethernet muaj cov cables zoo sib xws thiab cov khoom siv rau Fast Ethernet, tab sis nws muaj ntau yam thiab kev lag luam. Nrog rau kev txhim kho txuas ntxiv ntawm Gigabit Ethernet, ntau cov ntawv tshaj tawm tau tshwm sim, xws li 40G Ethernet thiab 100G Ethernet. Gigabit Ethernet muaj cov txheej txheem sib txawv ntawm lub cev, xws li 1000BASE-X, 1000BASE-T, thiab 1000BASE-CX.
Cov saum toj no yogtus Kev taw qhia luv luv ntawm Gigabit Ethernet thiab ceev Ethernet coj los rau koj los ntawm ShenzhenHDV Photoelectron Technology LTD thiab SShenzhenHDV Photoelectron Technology LTD yog lub tuam txhab tshwj xeeb hauv kev sib txuas lus kho qhov muag raws li cov khoom siv tseem ceeb, lub tuam txhab tsim khoom:ONU series, kho qhov muag module series,OLT series, transceiver series yog kub series ntawm cov khoom.
Kev taw qhia ntawm OpticalFibFyuam kev
Feem ntau ntawm cov fibers optical peb feem ntau pom yog optical fiber jumpers, uas yog, ob qhov kawg muaj cov khoom sib txuas, uas tuaj yeem raug tso ncaj qha thiab tshem tawm yam tsis siv lwm cov cuab yeej, qhov kev sib txuas yog hais txog SC, FC, LC thiab lwm yam kev faib tawm. .
Thiab dab tsi yog qhov tseem ceeb, raws li lub npe txhais tau hais tias nws tuaj yeem muab ntxig thiab rub tawm ntawm cov tub ntxhais, feem ntau yog ua los ntawm ceramic, cov tub ntxhais feem ntau yog tib lub sijhawm raws li qhov sib txuas, lossis hais dav dav, cov tub ntxhais sib npaug sib npaug rau cov khoom sib txuas. , qhov tshwj xeeb yog dab tsi? Cia kuv qhia koj qhov no maj mam.
Cov tub ntxhais hauv cov liab qab fiber ntau yog qhov nyias nyias thiab yooj yim tawg, yog li qee yam yuav tsum tau tiv thaiv nws. Rau nruab nrab ntawm cov fiber ntau, peb yuav teeb lub cladding los npog cov tub ntxhais los ua lub luag haujlwm tiv thaiv, tom qab ntawd rau tus Tsov tus tw ntawm cov fiber ntau peb siv ceramic core. Muaj ib lub qhov me me heev nyob rau hauv nruab nrab ntawm cov tub ntxhais, cov tub ntxhais yog pierced los ntawm lub qhov no nyob rau hauv cov hlau ib feem thiab ces tawm ntawm lub ceramic ib feem, qhov ntxiv yog txiav tawm ntawm lub ceramic sab, thiab ces muab lub cuab tam los zom. qhov ntxiv qhov tiaj tus, thiab ceev faj thaum sib tsoo, lub zog ntau dhau yuav ua rau cov tub ntxhais hauv cov tub ntxhais tawg. (Xiabian nco ntsoov tias lub hauv paus tseem ceeb tau muab tshem tawm los ntawm txhais tes thaum lub sijhawm sim hauv tsev kawm ntawv. Thaum lub teeb xa mus, nws pom tias lub taub hau ntsaws emits lub teeb liab pom tseeb, tab sis lub zog ntsuas tsis siab, vim tias lub teeb tsis yog lawm. propagated nyob rau hauv ib txoj kab ncaj nraim, tab sis yog dispersed, uas ua rau ib tug heev tsawg lub teeb ntsuas tus naj npawb ntawm cov hlau kawg yog nruab nrab ntawm lub optical fiber, uas yog feem ntau tiv thaiv los ntawm cladding thiab txheej ntawm lub taub hau thiab nruab nrab ib feem yuav tsum tau glued ua ke, tsis yog tsuas yog rau kev sib txuas ntawm cov khoom sib txuas, tab sis kuj tseem tiv thaiv lub teeb dhau ntawm qhov tseeb, cov hlau tseem ceeb tsis tas yuav txuas nrog cov khoom siv kho qhov muag, nws kuj tseem siv tau rau BOSA ntau lawm.
ShenzhenHDV Photoelectron TechnologyLTD. coj koj cov lus piav qhia ntawm "optical fiber plug", thiab peb lub tuam txhab yog cov kws tshaj lij kev sib txuas lus cov khoom siv kho qhov muag, cov khoom tseem ceeb npog ntau dua tshajONU series,OLT series, optical module series, transceiver series thiab hais txog. Cov khoom siv saum toj no muaj ntau yam kev qhia tshwj xeeb thiab cov qauv los muab cov kev pabcuam tshwj xeeb rau cov kev xav tau sib txawv network, txais tos koj tuaj txog.
