GigPeak, Inc. announced a 64 GBd quad-channel linear optical modulator driver for 400G/600G coherent optical networks. The GX66471 will support 16- and 64-QAM, addressing the needs of both 400G and 600G systems. It has a differential input and single-end output, with a 4.5 Vpp output swing for driving lithium niobate Mach-Zehnder modulators.

The driver has low power consumption and is assembled in a 14 mm x 9.1 mm surface-mount package, making it compatible with line card and pluggable module form factors, such as the CFP2-ACO.

GigPeak will be demonstrating the GX66471 at OFC2017, the annual optical networking and communications conference, which will be held from March 19 to 23 in Los Angeles.

Koichi Murata, GigPeak’s senior director of marketing for telecom products, said, “We are happy to see the successful sampling and evaluation of our newly released GX66471, offering our telecom customers an innovative driver solution for the next generation of 400 Gbps/600 Gbps coherent applications. The introduction of this product allows us to provide our customers with a solid transmitter product portfolio, in addition to our existing connectorized GPPO and SMT drivers for 100 Gbps and 200 Gbps applications.”

GigPeak is being acquired by IDT for approximately $250 million. Announced on February 13, 2017, IDT has begun buying GigPeak stock through a cash tender offer, which will close at midnight (EDT) on April 3, 2017.
