Intambo yesantya esiphezulu ye-DAC(Intambo eNcamathise ngqo) ngokubanzi iguqulelwa njengentambo ethe ngqo, intambo yobhedu eqhagamshelweyo ngqo okanye intambo ekhawulezayo. Ichazwa njengesicwangciso soqhagamshelo olufutshane olunexabiso eliphantsi esithatha indawo yeemodyuli ze-optical. Zombini iziphelo zentambo ekhawulezayo zineemodyuli Iindibano zentambo, iiports ezingatshintshwayo, iintloko zemodyuli kunye neentambo zobhedu azinakwahlulwa, kodwa xa kuthelekiswa neentambo ze-optical module ezisebenzayo (Iintambo ze-Active Optical), iimodyuli zesixhumi kwiintambo ezikhawulezayo azinazo ii-laser ze-optical ezibizayo kunye nezinye izinto ze-elektroniki, ngoko ke ukonga okukhulu kwindleko kunye nokusetyenziswa kwamandla kwizicelo zomgama omfutshane. Ngesantya esiphezulu se-Ethernet, i-cloud computing, i-Intanethi yezinto, kunye namaziko edatha ebonakalayo, kuye kwabekwa iimfuno ezingaphezulu kubaqhubi beziko ledatha. Isantya sedatha sisendleleni eya kwi-400G, ngoko ke ukongeza kuqhagamshelo olungaphakathi kwe-3-5m kwiseva, i-DAC ingasetyenziswa (iimitha ezi-5-7 kufuneka zisebenzise izixhobo zokukhusela ezizodwa ukuhlangabezana neemfuno zempawu). Uqhagamshelo olungaphaya kwale migama ngokubanzi luqatshelwa yi-AOC.
Isantya esiphezulu sisuka kwi-10G SFP+ ukuya kwi-SFP+ Intambo
I-10G SFP+ ukuya kwi-SFP+ DAC isebenzisa i-passive twinaxial cable assembly kwaye iqhagamshela ngqo kwi-SFP+ module, equka uxinano oluphezulu, amandla aphantsi, iindleko eziphantsi, kunye ne-low latency.
Zeziphi iintlobo zeentambo ezikhawulezayo ze-10G SFP+ ukuya kwi-SFP+ ezikhoyo?
Ngokubanzi, kukho iintlobo ezintathu zeentambo ezikhawulezayo ze-10G SFP+ ukuya kwi-SFP+:
Intambo ye-10G SFP+ esisiseko sobhedu esingenamsebenzi (DAC),
Intambo ye-10G SFP+ yeCopper Core esebenzayo ekhawulezayo (i-ACC),
Intambo ye-Optical esebenzayo ye-10G SFP+ (AOC),
Zilungele uqhagamshelo lwenethiwekhi ngaphakathi kwirakhi naphakathi kweerakhi ezikufutshane kwaye zixabisa kakhulu.
Intambo ye-SFP+ passive copper core high-speed cable inika ujongano lombane ngqo phakathi kweziphelo ezimbini zentambo ehambelanayo, kwaye umgama woqhagamshelo unokufikelela kwi-12m. Nangona kunjalo, ngenxa yobunzima obukhulu bentambo kunye nengxaki yokuthembeka kwesignali, ubude bokusetyenziswa kwayo ngokubanzi bunqunyelwe phakathi kwe-7m kunye ne-10m.
Intambo yesantya esiphezulu ukusuka kwi-40G QSFP+ ukuya kwi-QSFP+
Intambo yesantya esiphezulu ye-40G (i-DAC) ibhekisa kwintambo edibanisayo ene-transceivers ze-fiber optic kuzo zombini iziphelo, enokufikelela kuthumelo lwedatha lwe-40Gbps kwaye sisisombululo soqhagamshelo olukhawulezayo olungabizi kakhulu. Iintambo zesantya esiphezulu ze-40G eziqhelekileyo zinokwahlulwa zibe ziintlobo ezintathu: 40G QSFP+ ukuya kwi-QSFP+DAC, 40GQSFP+ ukuya kwi-4*SFP+DAC, kunye ne-40GQSFP+ ukuya kwi-4XFP+DAC.
I-40G QSFP+ ukuya kwi-QSFP+ DAC yenziwe ngee-transceivers ezimbini ze-40G QSFP+ optical kunye neengcingo ze-copper core. Le ntambo ikhawulezayo ingasetyenziselwa ukwenza uqhagamshelo lwee-ports ze-40G QSFP+ ezikhoyo kwii-ports ze-40G QSFP+, ngokubanzi kumgama we-7m kuphela.
I-40G QSFP+ ukuya kwi-4×SFP+ DAC yenziwe nge-transceiver enye ye-40G QSFP+ optical, i-copper core wire kunye ne-transceivers ezine ze-10G SFP+. Isiphelo esinye yi-interface ye-40G QSFP+, ehlangabezana neemfuno ze-SFF-8436, kwaye esinye isiphelo zii-interfaces ezine ze-10G SFP+. , ngokuhambelana neemfuno ze-SFF-8432, esetyenziswa kakhulu ukwenza unxibelelwano phakathi kwezixhobo ze-40G kunye ne-10G (i-NIC/HBA/CNA, izixhobo zokutshintsha kunye neseva), ngokweemfuno zomthengi zobude beentambo kuzo zombini iziphelo, ngokubanzi ngaphakathi kwe-7m kuphela. Umgama, okwangoku yeyona nto ingabizi kakhulu kwaye ilula ukuyifikelela ekuguquleni i-switch port.
I-40G QSFP+ ukuya kwi-4XFP DAC yenziwe nge-transceiver enye ye-40G QSFP+ optical, i-copper core wire kunye ne-10G XFP optical transceivers ezine. Ekubeni i-XFP fiber optic transceiver ingenawo umgangatho we-DAC copper cable, imbuyekezo yesignali enikwa sisixhobo iphantsi, kwaye ukulahleka kwentambo ngokwayo kukhulu kakhulu. Ingasetyenziselwa kuphela uthumelo lomgama omfutshane, ngokubanzi ngaphakathi komgama we-2m. Ke ngoko, le ntambo yesantya esiphezulu ingasetyenziselwa ii-Interconnects ezikhoyo ze-40G QSFP+ ports ukuya kwii-4 XFP ports.
