Worlds’ first single wavelength flexible PHY solution for 100G and beyond Data Center connections

FlexPhy: Single optics, Maximum speed

Pioneering the transition to 100G on a single wavelength, the revolutionary FlexPhy product line delivers best-in-class DSP based 100G and 400G ICs for next generation Data Center and wireless network architecture. FlexPhy products utilize leading-edge Digital Signal Processing (DSP) and mixed signal technologies combined with PAM4 single wavelength technology, reducing the number of optical components and easing opto-electronic bandwidth requirements, resulting in an unparalleled reduction of overall infrastructure costs, power and network complexity. MultiPhy’s innovative technology can be deployed within Data Centers (Intra-connection) for switch to switch connections and between Data Centers (Interconnection) with connection distances between 2km-10km and up to 80km respectively. This same technology can also enable the emerging 5G cloud RAN networks by realizing ultra-high capacity fronthaul connections. FlexPhy easily integrates into various form factors including QSFP28 pluggable modules and onto the host board, further enabling the lowest cost, highest density, and most flexible solutions required by the market.


FlexPhys’ unique approach, powered by patented DSP and mixed signal technologies employs PAM4 modulation of up to 60GBaud over a single wavelength, several Forward Error Correction (FEC) schemes as well as 25G and 50G SERDES. The product line is implemented in compliance with the IEEE future standard amendments 802.3cd (100GBASE-DR) and 802.3bs (400GBASE-DR4) and is fabricated in a high speed, low-power 16nm CMOS process.
