MultiPhy aims 100G single-wavelength PAM4 DSP at 5G cloud RAN applications

MultiPhy Ltd. used Mobile World Congress this week to unveil the MPF3101-SRW, a 100G single-wavelength PAM4 DSP device aimed at 5G cloud radio access network (RAN) applications. The programmable device also supports 25G and 50G transmission rates, making it applicable in a variety of applications, including those where network upgrades are anticipated.

The MPF3101-SRW leverages advanced DSP and mixed-signal technologies which, when combined with PAM4 modulation, enable increased data rates as well as lower power consumption and cost, MultiPhy says. The device will operate in extended temperature range applications and is designed to support QSFP28 form factors. It also supports Option 10 of the CPRI standard.

The company would appear to have at least one customer for the device. "5G wireless deployments present a strong potential opportunity for the entire optical industry," commented Osa Mok, co-founder and chief marketing officer of InnoLight, via a MultiPhy press release. "InnoLight's 100G single-wavelength optical modules enabled by MultiPhy's innovative PAM4 DSP are instrumental in realizing this opportunity in a timely fashion."

"The upcoming upgrade to 5G wireless networks is creating a strong demand for new, high-performance optical connectivity solutions," added Avi Shabtai, CEO of MultiPhy, in the same press statement. "The demand for 100G connections that allow the build out of these networks is clearly emerging, and the MPF3101-SRW is poised to become the core element of these network connections."

The introduction of the MPF3101-SRW follows earlier discussions of the MPF3101 100G single-wavelength PAM4 DSP line at ECOC 2017 (see "MultiPhy unveils MPF3101 PAM4 DSP for single-wavelength 100-Gbps applications").
