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.

100G QSFP28-SR4 optical modules

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.
