Module imatembenuza njira zolowetsamo za 4 (ch) za 25.78Gbps ku 27.95Gbps deta yamagetsi ku ma 4 ma sign optical lanes, ndikuwachulukitsa mu njira imodzi ya 100Gb / s optical transmission. Mobwerezabwereza, kumbali yolandira, module optically de-multiplexes 100Gb / s yolowera muzitsulo za 4, ndikuwatembenuzira ku misewu ya 4 yotulutsa deta yamagetsi. Chingwe cha riboni cha fiber chokhala ndi cholumikizira cha MPO/MTP kumapeto kulikonse chimamangirira mu chotengera cha module ya QSFP28. Mayendedwe a chingwe cha riboni ndi "makiyi" ndipo zikhomo zowongolera zilipo mkati mwa chotengera cha module kuti zitsimikizire kulondola koyenera. Chingwe nthawi zambiri sichikhala chopindika (kiyi mpaka makiyi apamwamba) kuwonetsetsa kuti njira yoyenera imayendera. Kulumikizana kwamagetsi kumatheka ngakhale cholumikizira cha z-pluggable 38-pin IPASS®. Gawoli limagwira ntchito kuchokera ku mphamvu imodzi ya + 3.3V ndi zizindikiro zolamulira zapadziko lonse za LVCMOS / LVTTL monga Module Present, Reset, Interrupt and Low Power Mode zilipo ndi ma modules. A 2-waya serial mawonekedwe akupezeka kuti atumize ndi kulandira zizindikiro zowongolera zovuta komanso kupeza chidziwitso cha digito.
