I-DAC eqhelekileyo yokuhlelwa kwentambo yesantya esiphezulu

Intambo ye-DAC enesantya esiphezulu(I-Direct Attach Cable) ngokuqhelekileyo iguqulelwa njengekhebula elithe ngqo, intambo yobhedu okanye intambo yesantya esiphezulu.Ichazwa njengexabiso eliphantsi lesicwangciso soxhumo olufutshane oluthatha indawo yeemodyuli ze-optical.Zombini iziphelo zentambo enesantya esiphezulu zineemodyuli Iindibano zekhebula, izibuko ezingatshintshiyo, iintloko zemodyuli kunye neentambo zobhedu azikwazi ukwahlulwa, kodwa xa kuthelekiswa nemodyuli ye-optical cables optical cables (Active Optical Cables), iimodyuli zokudityaniswa kwiintambo ezinesantya esiphezulu zenza. ungabinazo iilaser zamehlo ezibizayo kunye nezinye izinto ze-elektroniki, ngoko ke Ukonga okuBalulekileyo kwiindleko kunye nokusetyenziswa kwamandla kwizicelo zomgama omfutshane.Ngezantya ze-Ethernet eziphezulu, i-computing yefu, i-Intanethi yeZinto, kunye namaziko edatha ebonakalayo, iimfuno ezingaphezulu zibekwe kubaqhubi beziko ledatha.Isantya sedatha ngokwenene sisendleleni eya kwi-400G, ngoko ke ukongeza kwikhonkco ngaphakathi kwe-3-5m kumncedisi, i-DAC ingasetyenziselwa (iimitha ezi-5-7 kufuneka zisebenzise izinto ezikhethekileyo zokugquma ukuze zihlangabezane neemfuno zeempawu).Uxhulumaniso olungaphaya kwale migama lubonwa ngokubanzi yi-AOC.

I-10G SFP + ukuya kwi-SFP + isantya esiphezulu Intambo

I-10G SFP + ukuya kwi-SFP + DAC isebenzisa i-passive twinaxial cable assembly kwaye idibanisa ngokuthe ngqo kwimodyuli ye-SFP +, ebonisa ubuninzi obuphezulu, amandla aphantsi, ixabiso eliphantsi, kunye ne-latency ephantsi.

Ziziphi iintlobo ze-10G SFP + ukuya kwi-SFP + iintambo zesantya esiphezulu ezikhoyo?

Ngokubanzi, kukho iintlobo ezintathu ze-10G SFP+ ukuya kwi-SFP+ iintambo ezinesantya esiphezulu:

I-10G SFP + i-copper passive core cable (DAC)

I-10G SFP + iCable Core esebenzayo yeCopper High Speed ​​​​Cable (ACC),

I-10G SFP+ iCable Optical Cable (AOC),

Zikulungele uqhagamshelo lwenethiwekhi ngaphakathi kwerack naphakathi kweerack ezikufutshane kwaye zibiza kakhulu.

I-SFP + i-copper passive core ye-high-speed cable inika umbane ochanekileyo phakathi kweziphelo ezimbini zentambo ehambelanayo, kwaye umgama wokudibanisa unokufikelela kwi-12m.Nangona kunjalo, ngenxa yobunzima obunzima bekhebula kunye nokuqwalasela ingxaki yengqibelelo yesignali, ubude bayo bokusetyenziswa Ngokuqhelekileyo bukhawulelwe phakathi kwe-7m kunye ne-10m.

I-40G QSFP + ukuya kwi-QSFP + iCable yesantya esiphezulu

Intambo ye-40G yesantya esiphezulu (i-DAC) ibhekisela kwintambo yokudibanisa kunye ne-fiber optic transceivers kuzo zombini iziphelo, ezinokufikelela kwi-40Gbps yokuhanjiswa kwedatha kwaye iyisisombululo esineendleko eziphezulu ze-intanethi.Iintambo eziqhelekileyo ze-40G zesantya esiphezulu zinokuhlulwa zibe ziintlobo ezintathu: 40G QSFP + ukuya kwi-QSFP + DAC, 40GQSFP + kwi-4 * SFP + DAC, kunye ne-40GQSFP + kwi-4XFP + DAC.

I-40G QSFP + ukuya kwi-QSFP + i-DAC iqulunqwe ezimbini ze-40G QSFP + i-transceivers optical kunye neengcingo ezingundoqo zethusi.Le ntambo yesantya esiphezulu ingasetyenziselwa ukuqonda ukudibanisa kwe-40G QSFP + izibuko ezikhoyo kwi-40G QSFP + izibuko, ngokubanzi kuphela ngaphakathi kwe-7m.umgama.

I-40G QSFP + ukuya kwi-4 × SFP + DAC yenziwe nge-40G QSFP + i-transceiver optical, i-copper core wire kunye nee-transceivers ezine ze-10G SFP +.Esinye isiphelo si-interface ye-40G QSFP +, ehlangabezana neemfuno ze-SFF-8436, kwaye enye isiphelo sine-10G SFP + interfaces ezine., ngokuhambelana neemfuno ze-SFF-8432, ezisetyenziselwa ukuqaphela uxhulumaniso phakathi kwe-40G kunye ne-10G izixhobo (NIC / HBA / CNA, izixhobo zokutshintsha kunye nomncedisi), ngokweemfuno zomthengi ubude beentambo kuzo zombini iziphelo, ngokubanzi kuphela phakathi kwe-7m.Umgama, okwangoku ngowona unoqoqosho kwaye kulula ukufikelela kwinguquko yokutshintsha izibuko.

I-40G QSFP + ukuya kwi-4XFP DAC yenziwe nge-40G QSFP + i-transceiver optical, i-copper core wire kunye nee-transceivers ezine ze-10G XFP.Ekubeni i-transceiver ye-fiber optic ye-XFP ayinayo i-DAC ye-copper ye-copper standard, imbuyekezo yesignali enikwe isixhobo iphantsi, kwaye ukulahlekelwa kwekhebula ngokwayo kukhulu kakhulu.Ingasetyenziselwa kuphela ukuhanjiswa komgama omfutshane, ngokubanzi kumgama we-2m.Ngoko ke, le ntambo yesantya esiphezulu ingasetyenziselwa i-Interconnects ekhoyo ye-40G QSFP + izibuko kwii-4 XFP port.
