Gigalight Launched First Generation 100G QSFP28 Family of Products

On August 21 2015, Gigalight officially launched its first generation 100G QSFP28 family of products, including 100G QSFP28-SR4 optical transceiver, 100G QSFP28 active optical cable and 100G QSFP loopback transceiver. Gigalight has carried live demo to these new products at the 17^th CIOE (China International Optoelectronic Expo) in Shenzhen, China.

Gigalight 100G QSFP28-SR4 Transceiver

The first generation 100GE QSFP28 SR4 design performance conforms to protocol standard of IEEE 802.3bm 100GBASE SR4 and InfiniBand EDR. Its emitted optical power ranges in +-0.5dbm. Received OMA parameter is a bit lower than protocol standard; still it can totally be applied to OM3 optical fiber 75meter transfer and OM4 optical fiber 100meter transfer. The practical test environment is on the basis of stricter SER test standard (<10^-15), there’s no single error code while transferring OM4 optical fiber. This transceiver uses Gigalight original lens and optical engine, integrates 4channels of 25Gbps data channel, classic consumption is 3.2W, and supporting digital diagnosis function on the project except TX power. This transceiver has obtained excellent optical and electric eye mask.
