Acacia bets on silicon as coherent enters its next phase

Gazettabyte interviewed Acacia Communications’ president and CEO, Murugesan ‘Raj’ Shanmugaraj, as the coherent technology company celebrates its 10th anniversary.


Acacia Communications has come a long way since Raj Shanmugaraj (pictured) first joined the company as CEO in early 2010. “It was just a few conference rooms and we didn't have enough chairs,” he says.

The company has since become a major optical coherent player with revenues of $340 million in 2018; revenues that would have been higher but for the four-month trade ban imposed by the US on Chinese equipment maker ZTE, an Acacia customer.

And as the market for coherent technology continues to grow, Acacia and other players are preparing for new opportunities. 

“We are still in the early stages of the disruption," says Shanmugaraj. “You will see higher performance [coherent systems] in some parts of the network but there is going to be growth as coherent moves closer to the network edge.”

The Open ROADM MSA adds new capabilities in Release 2.0

The Multi-Source Agreement (MSA) for open reconfigurable add-drop multiplexers (ROADM) group expects to publish its second release in the coming months. The latest MSA specifications extend optical reach by including line amplification and adds support for flexible grid and lower-speed tributaries with OTN switching.

Xavier PougnardThe Open ROADM MSA, set up by AT&T, Ciena, Fujitsu and Nokia, is promoting interoperability between vendors’ ROADMs by specifying open interfaces for their control using software-defined networking (SDN) technology. Now, one year on, the MSA has 10 members, equally split between operators and systems vendors.

Orange joined the Open ROADM MSA last July and says it shares AT&T’s view that optical networks lack openness given the proprietary features of the vendors’ systems.
