Ngokuqhelekileyo, kukho iindidi ezimbini zemicu: ezo zixhasa iindlela ezininzi zokusasaza okanye iindlela ezinqamlezayo zibizwa ngokuba yi-multi-mode fibers (MMF), kwaye ezo zixhasa imo enye zibizwa ngokuba yi-single-mode fibers (SMF). Kodwa yintoni umahluko phakathi kwabo? Ukufunda eli nqaku kuya kukunceda ufumane impendulo.
Isishwankathelo seNdlela enye Vs iMultimode yeFiber Optic Cable
I-fiber yemowudi enye ivumela ukusasazwa kwemowudi enye kuphela yokukhanya ngexesha, ngelixa i-multimode fiber optical inokusasaza iindlela ezininzi. Umahluko ophambili phakathi kwabo ukwi-fiber core diameter, i-wavelength kunye nomthombo wokukhanya, i-bandwidth, i-sheath yombala, umgama, ixabiso, njl.
IMowudi Eyodwa Vs I-Multimode Fiber, Yintoni Umahluko?
Ixesha lokuthelekisa imowudi enye vs. multimodei-fiber opticalkwaye baqonde iiyantlukwano zabo.
I-Core Diameter
Intambo yeNdlela eNye inobungakanani obungundoqo obuncinci, obuqhele ukuba yi-9μm, ivumela ukuthotywa okuphantsi, i-bandwidths ephezulu, kunye nemigama emide yothumelo.
Ngokwahlukileyo, i-Multimode i-fiber optical ine-core size enkulu, ngokuqhelekileyo i-62.5μm okanye i-50μm, kunye ne-OM1 kwi-62.5μm kunye ne-OM2 / OM3 / OM4 / OM5 kwi-5μm. Nangona kukho umehluko ngobukhulu, ayibonakali lula ku-Eve ohamba ze njengoko zincinci kunobubanzi beenwele zomntu. Ukujonga ikhowudi eprintiweyo kwintambo yefiber optic inokunceda ukuchonga uhlobo.
Ngokhuselo olukhuselayo, zombini imodi enye kunye ne-multimode fibers inobubanzi be-125μm.
Ubude beWaveleng kunye noMthombo wokukhanya
I-Multimode optical fiber, kunye nobukhulu bayo obuphambili, isebenzisa imithombo yokukhanya ephantsi kwexabiso eliphantsi njenge-LEDs ukukhanya kunye ne-VCSELs kwi-850nm kunye ne-1300nm wavelengths. Ngokwahlukileyo, intambo yemowudi enye kunye nombindi wayo omncinci, isebenzisa iilaser okanye i-laser diode ukuvelisa ukukhanya okufakwe kwintambo, eqhelekileyo kumaza e-1310nm kunye ne-1550nm.
Ububanzi
Ezi ntlobo zimbini zefayibha zahlukile kubuchule be-bandwidth. Ifayibha yendlela enye inikezela ngebhanwidth ephantse ibenamda ngenxa yenkxaso yayo yemowudi yomthombo wokukhanya omnye, ekhokelela ekuthotyweni nasekusasazekeni okusezantsi. Lukhetho olukhethwayo lonxibelelwano olukhawulezayo kwimigama emide.
Kwelinye icala, ifayibha yemultimode inokuhambisa iindlela ezininzi zamehlo, kodwa inomtsalane ophezulu kunye nokusasazwa okukhulu, inciphisa umda wayo.
Ifayibha yemodi enye igqithisa i-multimode ifayibha yamehlo ngokwendlela yomthamo webhanwidth.
Ukuthotywa
I-fiber yemowudi enye ine-attenuation esezantsi, ngelixa i-multimode ifayibha isesichengeni sokuthomalalisa.
Umgama
Ukuthotywa kwentambo yendlela enye kunye nemowudi yosasazo yenza umgama omde wothumelo kunemowudi. I-Multimode ineendleko ezisebenzayo kodwa inqunyelwe kwiikhonkco ezimfutshane (umzekelo, i-550m ye-1Gbps), ngelixa imowudi enye isetyenziselwa ukuhanjiswa kwexesha elide kakhulu.
Iindleko
Xa kuqwalaselwa ixabiso lilonke, amacandelo amathathu adlala indima ebalulekileyo.
Iindleko zoFakelo
Iindleko zokufakela i-fiber yemodi enye zihlala zibonwa ziphezulu kunentambo ye-multimode ngenxa yeenzuzo zayo. Noko ke, inyaniso yahlukile. ngenxa yokuvelisa ngokufanelekileyo, ukonga i-20-30% xa kuthelekiswa ne-multimode fiber. Kwi-pricier OM3/OM4/OM5 fibers, imowudi enye ingagcina ukuya kuthi ga kwi-50% okanye ngaphezulu. Nangona kunjalo, iindleko ze-optical transceiver kufuneka nazo zithathelwe ingqalelo.
Iindleko ze-Optical Transceiver
I-transceiver ebonakalayo licandelo lexabiso elibalulekileyo kwi-fiber cabling, ibalwa inxalenye enkulu, ngamanye amaxesha ukuya kwi-70% yeendleko zizonke. Ii-transceivers zemowudi enye ngokubanzi zibiza i-1.2 ukuya kumaxesha angama-6 ngaphezulu kwe-multimode. Oku kungenxa yokuba imowudi enye isebenzisa i-laser diode ephezulu yamandla (LD), ebiza kakhulu, ngelixa izixhobo zemultimode zisebenzisa i-LED okanye iVCSELS enexabiso eliphantsi.
Iindleko zoPhuculo lweNkqubo
Ngokuhambela phambili okukhawulezayo kwethekhnoloji, iinkqubo zekhebhuli zihlala zifuna ukuphuculwa kunye nokwandiswa. Imowudi enye ye-fiber optic cabling inika ukuqina okukhulu, ukuguquguquka, kunye nokuguquguquka. Intambo ye-Multimode, ngenxa ye-bandwidth yayo elinganiselweyo kunye nezakhono zomgama omfutshane, zinokuba nzima ukuhlangabezana neemfuno zexesha elizayo zokuhanjiswa komgama omde kunye nomthamo ophezulu.
Ukuphucula inkqubo ye-fiber optic yemowudi ilula ngakumbi, ibandakanya ukutshintsha kuphela i-switch kunye ne-transceivers ngaphandle kwesidingo sokubeka iifayili ezintsha. Ngokwahlukileyo, kwintambo ye-multimode, ukuphuculwa ukusuka kwi-OM2 ukuya kwi-OM3 kwaye emva koko ukuya kwi-OM4 yokuhanjiswa kwesantya esiphezulu kuya kuba neendleko eziphezulu kakhulu, ngakumbi xa utshintsha iifiber ezibekwe phantsi komgangatho.
Isishwankathelo, i-multimode inexabiso elisebenzayo kumgama omfutshane, ngelixa imowudi enye ifanelekile kumgama ophakathi ukuya kumde.
Umbala
Ikhowudi yombala yenza lula uhlobo lwentambo yokuchongwa. I-TlA-598C ibonelela ngekhowudi yombala ecetyisiweyo kushishino ukuze ibonakale lula.
I-Multimode i-OM1 kunye ne-OM2 idla ngokuba nejacket ye-orange.
I-OM3 ihlala ineebhatyi zemibala ye-Aqua.
I-OM4 ihlala ineebhatyi zemibala ye-Aqua okanye yeViolet.
I-OM5 yayinemibala eluhlaza okwesibhakabhaka.
Imowudi enye OS1 kunye ne-OS2 ngokwesiqhelo neebhatyi eziYellow.
Isicelo
Intambo yemowudi enye isetyenziswa ikakhulu kumqolo omde kunye neenkqubo zemetro kwi-telecom, datacom, kunye neenethiwekhi zeCATV.
Kwelinye icala, intambo yemultimode isetyenziswa ikakhulu kumgama omfutshane njengamaziko edatha, icomputing yamafu, iinkqubo zokhuseleko, kunye neeLAN (IiNethiwekhi zeNdawo yeNgingqi).
Ukuqukumbela
Ukuqukumbela, i-fiber cabling yendlela enye ilungele ukuhanjiswa kwedatha ixesha elide kwiinethiwekhi zabathwali, ii-MAN, kunye neePON. I-Multimode fiber cabling, ngakolunye uhlangothi, isetyenziswa ngokuqhelekileyo kwishishini, amaziko edatha, kunye neeLAN ngenxa yokufikelela okufutshane. Isitshixo kukukhetha uhlobo lwefayibha olulungela iimfuno zenethiwekhi yakho ngelixa uqwalasela ixabiso lilonke lefayibha. Njengomyili womnatha, ukwenza esi sigqibo kubalulekile kulungiselelo lwenethiwekhi olusebenzayo noluthembekileyo.
