Cisco goes deeper into photonic, optical technology with $2.6B Acacia buy

Cisco: Optical-interconnect technologies are becoming increasingly strategic for data centers, service providers

Looking to bulk-up its optical systems portfolio, Cisco says it intends to buy Acacia Communications for approximately $2.6 billion.  The deal is Cisco’s largest since it [laid out $3.7B for AppDynamics][2] in 2017.

Acacia develops, manufactures and sells high-speed [coherent optical][3] interconnect products that are designed to transform networks linking data centers, cloud and service providers. Cisco is familiar with Acacia as it has been a “significant” customer of the optical firm for about five years, Cisco said.

Acacia’s other customers include Nokia Oyj, Huawei and ZTE. Cisco accounts for about 18% of its revenue, [according to Bloomberg’s supply-chain analysis][6].

"With the explosion of bandwidth in the multi-cloud era, optical interconnect technologies are becoming increasingly strategic,” said David Goeckeler, executive vice president and general manager of Cisco's networking and security business in a statement. “The acquisition of Acacia will allow us to build on the strength of our switching, routing and optical networking portfolio to address our customers' most demanding requirements."

For Cisco, one of the key drivers for making this deal was Acacia’s coherent technology – “a fancy term that means the ability to send optical signals over long distances,” said Bill Gartner, senior vice president of Cisco’s Optical Systems and Optics business.  “That technology today is typically delivered via a line card on a big chassis in a separate optical layer but with Acadia’s digital signal processing, ASIC and other technology we are looking to move that from a line card to a pluggable module that increases network capacity, but also reduces complexity and costs.”

In addition, Acacia uses silicon photonics as the platform for integration of multiple photonic functions for coherent optics, Gartner wrote in a [blog][7] about the acquisition. “Leveraging the advances in silicon photonics, each new generation of coherent optics products has enabled higher data transmission rates, lower power and higher performance than the one before.”

Recent research from [IHS Markit][8] shows that data center interconnections are the fastest growing segment for coherent transceivers.

“Acacia’s digital signal processing and small form-factor long-distance communications technology is strong and will be very valuable to Cisco in the long and short term,” said Jimmy Yu, vice president of the Dell'Oro Group.

The question many analysts have is the impact the sale will have on other Acacia customers Yu said.   “If wasn’t for Acacia selling to others, [such as Huawei, ZTE and Infinera] I don’t thise think vendors would have done as well as they have, and when Cisco owns Acacia it could be a different story,” Yu said.

The Acacia buy will significantly boost Cisco’s optical portfolio for application outside the data center.  In February [Cisco closed a deal to buy optical-semiconductor firm Luxtera][9] for $660 million, bringing it the advanced optical technology customers will need for speed and throughput for future data center and webscale networks.

The combination of Cisco’s and Luxtera’s capabilities in 100GbE/400GbE optics, silicon and process technology will help customers build future-proof networks optimized for performance, reliability and cost, Cisco stated.

The reason Cisco snatched-up Luxtera was its silicon photonics technology that moves data among computer chips optically, which is far quicker than today's electrical transfer, Cisco said. Photonics will be the underpinning of future switches and other networking devices.

"It seems that Cisco is going all in on being a supplier of optical components and optical pluggable: Luxtera (client side optical components and pluggable) and Acacia (line side optical components and pluggable)," Yu said.

"Unless Cisco captures more of the optical systems market share and coherent shipment volume, I think Cisco will need to continue selling Acacia products to the broader market and other system vendors due to the high cost of product development," Yu said.

The acquisition is expected to close during the second half of Cisco's FY2020, and upon close, Acacia employees will join Cisco's Optical Systems and Optics business within its networking and security business under Goeckeler.
