Preliminary and Proprietary 1 of 11 www.wavesplitter.com 100 Gbps QSFP28 Acti ve Optical Cable P/N: WST - QS28 - AOC x Cxx Feature  Compliant with 100GBASE - SR4 and CAUI - 4 specification per IEEE 802.3bm  Compliant to SFF - 8665 (QSFP28 Solution) Revision 1.8  Supp orts 100 Gbps data rate links up to 70m/ 100 m via OM3/ OM4 , respectively.  Low pow er consumption of max 2.5W  Hot plug gable electrical interface  Using standard 12/8 lane optical fiber with 3 - mm round cable  0 to 70°C case temperature operating range  RoHS - 6 Compliant (lead - free) Applications  Ethernet for 10 0GBASE - SR4  InfiniBand EDR, FDR, & QDR  HPC Interconnects  Propriet ary Interconnections General Description Quad Small Form - Factor Pluggable 28 (QSF P 28 ) active optical cables (AOC) are high - performance active optical cable with bi - directional sig nal transmission and aggregate 10 0 - Gbps bandwidth for both InfiniBand E DR and Ethernet 100G - SR 4 applications. Compared to conventional copper cables, longer and lighter optical cables enable the ease of complicated data - center cablings. The AOCs utilize multimode fiber with 850 - nm VCSELs and PIN PDs. The certificated cables have superior signal integrity and bit - error - rate, which enables reliable operation per formance.
