MultiPhy unveils 100G single-wavelength PAM-4 chip

A chip to enable 100-gigabit single-wavelength client-side optical modules has been unveiled by MultiPhy. The 100-gigabit 4-level pulse amplitude modulation (PAM-4) circuit will also be a key building block for 400 Gigabit Ethernet interfaces that use four wavelengths.

Dubbed the MPF3101, the 100-gigabit physical layer (PHY) chip is aimed at such applications as connecting switches within data centres and for 5G cloud radio access network (CRAN).

“The chip has already been sent out to customers and we are heading towards market introductions,” says Avi Shabtai, CEO of MultiPhy.

MultiPhy raises $17M to develop 100G serial interfaces

Start-up MultiPhy has raised U.S. $17 million to develop 100-gigabit single-wavelength technology for the data centre. Semtech has announced it is one of the companies backing the Israeli fabless start-up, the rest coming from venture capitalists and at least one other company.

MultiPhy is developing chips to support serial 100-gigabit-per-second transmission using 25-gigabit optical components. The design will enable short reach links within the data centre and up to 80km point-to-point links for data centre interconnect.

“It is not the same chip [for the two applications] but the same technology core,” says Avi Shabtai, the CEO of MultiPhy. The funding will be used to bring products to market as well as expand the company’s marketing arm.

MultiPhy eyeing 400 Gig after completing funding round 

MultiPhy is developing a next-generation chip design to support 100 and 400 Gigabit direct-detection optical transmission. The start-up raised a new round of funding in 2013 but has neither disclosed the amount raised nor the backers except to say it includes venture capitalists and a 'strategic investor'.

MultiPhy targets low-power coherent metro chip for 2013

MultiPhy has given first details of its planned 100 Gigabit coherent chip for metro networks. The Israeli fabless start-up expects to have samples of the device in 2013. 

"We can tolerate greater [signal] impairments which means the requirements on the components we can use are more relaxed"
