Iimpawu: ◊ Ithobela i40GbE XLPPI inkcukacha zombane ngeIEEE 802.3ba-2010 ◊ Ithobelana neQSFP+ SFF-8436 Iinkcukacha ◊ ​​I-Aggregate bandwidth ye > 40Gbps ◊ Isebenza kwi-10.3125 yedatha yombane ye-encod6/6 Gb ◊ QSFP MSA iyathobela ◊ Iyakwazi ukusasaza ngaphezulu kwe-100m kwi-OM3 Multimode Fiber (MMF) kunye ne-150m kwi-OM4 MMF ◊ Umbane oMnye +3.3V osebenzayo ◊ Ngaphandle kwemisebenzi yokuxilongwa kwedijithali ◊ Uluhlu lobushushu 0 °C ukuya kwi-70 °C iNxalenye yeRoHS ◊ Isebenzisa i-LC eqhelekileyo Intambo yefayibha eyi-duplex evumela ukuphinda kusetyenziswe isiseko sentambo ekhoyo Usetyenziso: ◊ 40 Gigabit Ethernet uqhagamshelo ◊ Uqhagamshelo lweDatacom/Telecom kunye noqhagamshelo lwerutha ◊ Udityaniso lwedatha kunye nezicelo ze-backplane ◊ Iprothokholi yobunini kunye nezicelo zoxinaniso Inkcazo: YiChannel-Four,Pluggable, LC Duplex, I-Fiber-Optic QSFP + Transceiver ye-40 Gigabit Ethernet Usetyenziso. Le transceiver yimodyuli ephezulu yokusebenza yonxibelelwano olufutshane lwedatha ye-duplex kunye nezicelo zoqhagamshelwano. Idibanisa imizila emine yedatha yombane kwicala ngalinye ekuhanjisweni nge-LC duplex fiber optic cable enye. Umzila ngamnye wombane usebenza kwi-10.3125 Gbps kwaye uhambelana ne-40GE XLPPI interface. I-transceiver yangaphakathi i-multiplexes i-XLPPI 4x10G i-interface kwi-20Gb / s iziteshi zombane ezimbini, ukuthumela kunye nokufumana i-optically nganye phezu kwe-fiber eyodwa ye-LC elula usebenzisa i-bi-directional optics. Oku kuphumela kwi-aggregate bandwidth ye-40Gbps kwi-duplex LC cable. Oku kuvumela ukuphinda kusetyenziswe i-LC duplex cabling infrastructure efakiweyo kwi-40GbE yesicelo. Umgama wokudibanisa ukuya kwi-100 m usebenzisa i-OM3 kunye ne-150m usebenzisa i-OM4 i-fiber optical ixhaswa. Ezi modyuli ziyilelwe ukuba zisebenze kwiinkqubo ze-multimode zefiber zisebenzisa i-wavelength ye-850nm kwelinye icala kunye ne-900nm kwelinye icala. I-interface yombane isebenzisa i-38 yoqhagamshelwano lwe-QSFP + uhlobo lwe-edge connector. I-optical interface isebenzisa i-LC duplex connector eqhelekileyo.
