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-optically ngayinye phezu kwe-fiber eyodwa ye-simplex ye-LC 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.
