'Industry’s first' 64 Gbaud linear modulator driver for 400G

By increasing the data rate on a single wavelength, operators can increase capacity and reduce the overall cost-per-bit of transmission. Metro networks can use higher order modulation formats at 32 Gbaud to achieve this but these higher order modulation formats such as 32 and 64 QAM have very limited reach due to signal-to-noise requirements. Long haul networks therefore require the use of higher baud rates up to 64G to achieve data rates of 400G on a single wavelength.

MACOM’s MAOM-006428 modulator driver features surface mount inputs and G3PO outputs to mate with the next generation high bandwidth modulator which is currently being standardized by the OIF. The device has linear performance to support higher order modulation formats with low power consumption and a compact form factor taking up <275mm² of PCB real estate.

“We believe that the MAOM-006428, in addition to being the industry’s first 64G baud linear modulator driver, provides customers with a revolutionary package design that delivers the high performance required by 64Gbaud in a cost effective form factor,” said Ray Moroney, Director of Product Marketing for High-Performance Analog at MACOM.
