Iindidi ze-SFP + iimodyuli ze-optical
Kwiimeko eziqhelekileyo, iimodyuli ze-SFP + ze-optical zihlelwa ngokwezicelo zangempela.Iintlobo eziqhelekileyo ziquka i-10G SFP +, i-BIDI SFP +, i-CWDM SFP +, kunye ne-DWDM SFP +.
I-10G SFP + imodyuli ye-optical
Olu hlobo lwemodyuli ye-optical yimodyuli eqhelekileyo ye-SFP + ye-optical, kwaye inokuthathwa njengenguqu ephuculweyo ye-1G SFP imodyuli ye-optical.Luyilo oluqhelekileyo kwimarike okwangoku, kwaye umgama omkhulu unokufikelela kwi-100KM.
I-BIDI SFP + imodyuli yokubona
Olu hlobo lwemodyuli ye-optical ithatha iteknoloji ye-WDM wavelength division, isantya esiphezulu sinokufikelela kwi-11.1G bps, kwaye ukusetyenziswa kwamandla kuphantsi.Ineejekhi ezimbini ze-fiber optical kunye nomgama wothumelo ophezulu yi-80KM.Ngokuqhelekileyo zisetyenziswa ngababini.Xa ukwakhiwa kwenethiwekhi kwiziko ledatha, kunokunciphisa inani le-fiber optical esetyenziswayo kunye neendleko zokwakha.
I-CWDM SFP + imodyuli yokubona
Olu hlobo lwemodyuli ye-optical luthatha iteknoloji ye-multiplexing ye-wavelength ye-coarse wavelength, kwaye isetyenziswa rhoqo kunye ne-fiber optical mode enye, enokugcina izibonelelo ze-fiber optical, kwaye iguquguquka ngakumbi kwaye ithembekile kuthungelwano, kwaye isebenzisa amandla aphantsi.Ukusebenzisa i-LC duplex optical interface, owona mgama mde unokufikelela kwi-80KM
I-DWDM SFP + imodyuli yokubona
Olu hlobo lwemodyuli ye-optical ithatha itekhnoloji ye-wavelength exineneyo yolwahlulo lwe-multiplexing, esetyenziswa kakhulu kuthumelo lwedatha lomgama omde.Umgama omkhulu wothumelo ungafikelela kwi-80KM.Ineempawu zesantya esiphezulu, umthamo omkhulu, kunye nokuqina okuqinileyo.
Isisombululo sokuhlanganiswa kwe-SFP + iimodyuli ze-optical kunye nokutshintsha
Iindidi ezahlukeneyo zeemodyuli ze-optical zixhunyiwe kwiitshintshi kwaye zingasetyenziselwa kwizisombululo ezahlukeneyo zokunxibelelana.Oku kulandelayo kukubonakaliswa kokusetyenziswa okusebenzayo kwe-SFP + iimodyuli ze-optical kunye nokutshintsha.
I-10G SFP + imodyuli ye-optical kunye ne-40G iskimu soqhagamshelwano lokutshintsha
Faka i-4 10G SFP + iimodyuli ze-optical kwi-10-Gbps SFP + i-port ye-switch enye, emva koko faka i-40G QSFP + imodyuli ye-optical kwi-40-Gbps QSFP + ichweba lolunye utshintsho, kwaye ekugqibeleni usebenzise i-jumper yefiber yesebe embindini Yenza uxhumano. .Le ndlela yokudibanisa iqonda ngokuyinhloko ukwandiswa kwenethiwekhi ukusuka kwi-10G ukuya kwi-40G, enokukhawuleza kwaye ihlangabezane neemfuno zokuphucula inethiwekhi yeziko ledatha.
Izilumkiso zokusetyenziswa kwe-SFP + iimodyuli zamehlo:
1. Xa usebenzisa imodyuli ye-optical, zama ukuphepha umbane ongatshintshiyo kunye namaqhuma.Ukuba amaqhuma ayenzeka, akukhuthazwa ukuba uqhubeke nokusebenzisa imodyuli ye-optical;2. Nika ingqalelo ngaphambili nangasemva kwimodyuli ye-optical, i-ring ring kunye neleyibhile kufuneka ijonge phezulu;3. Xa ufaka imodyuli ye-optical kwi-switch, zama ukuyityhalela ezantsi kangangoko.Ngokuqhelekileyo, kuya kubakho ukungcangcazela okuncinci.Emva kokufaka imodyuli ye-optical, ungakhupha ngobunono imodyuli ye-optical ukujonga ukuba isendaweni;4. Xa udibanisa imodyuli ye-optical, okokuqala udonsa isongo kwindawo ye-90 ° kwi-port optical, uze ukhuphe imodyuli ye-optical.
