Landa

Izici:

◊ Ihambisana nokucaciswa kukagesi kwe-40GbE XLPPI nge-IEEE 802.3ba-2010 ngayinye

◊ Ithobelana Nemininingwane ye-QSFP+ SFF-8436

◊ Umkhawulokudonsa ohlanganisiwe > 40Gbps

◊ Isebenza ku-10.3125 Gbps ngeshaneli kagesi ngayinye enedatha efakwe ikhodi engu-64b/66b

◊ I-QSFP MSA iyahambisana

◊ Iyakwazi ukuthumela ngaphezu kwe-100m ku-OM3 Multimode Fiber (MMF) kanye ne-150m ku-OM4 MMF

◊ Ukunikezwa kwamandla okukodwa +3.3V okusebenzayo

◊ Ngaphandle kwemisebenzi yokuxilonga yedijithali

◊ Ibanga lokushisa 0°C kuya ku-70°C

◊ Ingxenye Ethobelayo ye-RoHS

◊ Isebenzisa intambo evamile ye-LC duplex fiber evumela ukusetshenziswa kabusha kwengqalasizinda yekhebula ekhona

Izicelo:

◊ 40 Gigabit Ethernet ukuxhumana

◊ I-Datacom/Telecom switch & nokuxhumeka kwerutha

◊ Ukuhlanganiswa kwedatha nezinhlelo zokusebenza zendiza engemuva

◊ Iphrothokholi yobunikazi kanye nezicelo zokuminyana

Incazelo:

I-Four-Channel, Pluggable, LC Duplex, Fiber-Optic QSFP+ Transceiver ye-40 Gigabit Ethernet Applications.Le transceiver iyimojula yokusebenza okuphezulu yokuxhumana kwedatha ye-duplex yebanga elifushane kanye nezinhlelo zokusebenza zokuxhumanisa.Ihlanganisa imizila yedatha kagesi emine ohlangothini ngalunye ukuze idluliselwe ngentambo eyodwa ye-LC duplex fibre optic.Umzila ngamunye kagesi usebenza ku-10.3125 Gbps futhi uvumelana ne-40GE XLPPI interface.

I-transceiver yangaphakathi iphindaphinda i-XLPPI 4x10G isikhombimsebenzisi eziteshini ezimbili zikagesi ze-20Gb / s, idlulisela futhi yamukele i-optical ngayinye phezu kwe-fibre eyodwa ye-LC elula isebenzisa i-bi-directional optics.Lokhu kubangela umkhawulokudonsa ohlanganisiwe we-40Gbps ube yikhebula ye-LC eyiduplex.Lokhu kuvumela ukusetshenziswa kabusha kwengqalasizinda ye-LC duplex cabling efakiwe yohlelo lokusebenza lwe-40GbE.Xhuma amabanga afika ku-100 m usebenzisa i-OM3 kanye ne-150m usebenzisa i-OM4 fibre optical asekelwa.Lawa mamojula aklanyelwe ukusebenza phezu kwezinhlelo ze-multimode fibre kusetshenziswa ubude begagasi obungu-850nm ngakolunye uhlangothi kanye no-900nm ngakolunye uhlangothi.Isixhumi esibonakalayo sikagesi sisebenzisa isixhumi esinqenqemeni sohlobo lwe-38 QSFP+.I-optical interface isebenzisa isixhumi esivamile se-LC duplex.
