Iyi transceiver ndeye yakakwira performance module yepfupi-renji duplex data kutaurirana uye interconnect application. Iyo inosanganisa nzira ina dzemagetsi data munzira imwe neimwe mukufambisira pamusoro peiyo imwe LC duplex fiber optic tambo. Imwe neimwe nzira yemagetsi inoshanda pa10.3125 Gbps uye inoenderana ne40GE XLPPI interface. The transceiver mukati ma multiplexes an XLPPI 4x10G interface mumatanho maviri emagetsi e20Gb / s, kutumira uye kugamuchira imwe neimwe optically pane imwe simplex LC fiber uchishandisa bi-directional optics. Izvi zvinoguma mune aggregate bandwidth ye40Gbps mune duplex LC tambo. Izvi zvinobvumira kushandiswazve kweiyo yakaiswa LC duplex cabling infrastructure ye40GbE application. Batanidza madaro anosvika 100 m uchishandisa OM3 uye 150m uchishandisa OM4 optical fiber inotsigirwa. Aya mamodule akagadzirwa kuti ashande pamusoro pemultimode fiber masisitimu achishandisa zita rekureba re850nm kune rimwe mugumo uye 900nm kune imwe mugumo. Iyo yemagetsi interface inoshandisa 38 yekuonana QSFP + mhando edge yekubatanidza. Iyo optical interface inoshandisa yakajairwa LC duplex yekubatanidza.
