Gigalight release first-generation 100G QSFP28 family of products unveiled CIOE 2015

August 21, 2015, Gigalight officially released the first generation 100G QSFP28 family of products, including: 100G QSFP28-SR4 optical modules, 100G QSFP28 active optical cable (AOC) and 100G QSFP LOOPBACK module. Gigalight will demonstrate at the 17th CIOE China International Expo light scene.

The first generation of design performance 100GE QSFP28 SR4 meets IEEE 802.3bm 100GBASE SR4 and InfiniBand EDR protocol standard. The emitted light power range + -0.5dbm receiving OMA protocol parameters slightly lower standards, but to fully meet 75 meters OM3 fiber transmission and OM4 fiber 100 m transmission applications. The actual testing environment based on more stringent standard error rate testing (less than -15 times square), transmission OM4 fiber did not find any errors. The module uses Gigalight self-developed lens and light engine integrates four 25Gbps data channels and typically consumes 3.2W, support in addition to other projects outside TX power digital diagnostic functions. The module received a very good optical eye diagram and electrical eye performance.
