Acacia unveils its 400G coherent module portfolio

Acacia Communications has unveiled a full portfolio of 400-gigabit coherent optics and has provided test samples to customers, one being Arista Networks.

Delivering a complete set of modules offers a comprehensive approach to address the next phase of coherent optics, the company says. 

Tom WilliamsThe 400-gigabit coherent designs detailed by Acacia are implemented using the QSFP-DD, OSFP and CFP2 pluggable form factors.

Collectively, the pluggables support three performance categories: the 400ZR standard, OpenZR+ that is backed by several companies, and the coherent optics specification used for the Open ROADM multi-source agreement (MSA). 

“These are challenging specifications,” says Tom Williams, vice president of marketing at Acacia. “Even the 400ZR, where the objective has been to simplify the requirements.”

Nokia buys Elenion for its expertise and partnerships

Nokia will become the latest systems vendor to bolster its silicon photonics expertise with the acquisition of Elenion Technologies. 

The deal for Elenion, a privately-held company, is expected to be completed this quarter, subject to regulatory approval. No fee has been disclosed.

“If you look at the vertically-integrated [systems] vendors, they captured the lion’s share of the optical coherent marketplace,” says Kyle Hollasch, director of optical networking product marketing at Nokia. “But the coherent marketplace is shifting to pluggables and it is shifting to more integration; we can’t afford to be left behind.”

Cisco-Acacia blurs the optical ecosystem vendor divide

Cisco Systems’ acquisition of Acacia Communications would make it first to market with a 400ZR pluggable coherent interface. So claims Vladimir Kozlov, CEO of LightCounting Market Research. 

“This is the main reason Cisco is doing the deal,” says Kozlov. “It is very important for Cisco to get its core routers with DWDM optics and push network evolution in this direction.” 

Cisco is keen to grow its market share among service providers and lead in the development of software for automating telecom networks centred around routers, he says: “This will be the best way for Cisco to re-energise its optical transport business.”

Tom Williams, Acacia“We are planning to sample [the 400ZR] before the deal closes,” says Tom Williams, vice president for marketing at Acacia. “Our plan is to be first to volume, that is the most important thing.”

The acquisition is expected to be completed in the second half of Cisco’s fiscal year, 2020 (February-July 2020).

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.”

Data centre interconnect drives coherent

• NeoPhotonics announced at OFC a high-speed modulator and intradyne coherent receiver (ICR) that support an 800-gigabit wavelength

• It also announced limited availability of its nano integrable tunable laser assembly (nano-ITLA)  and demonstrated its pico-ITLA, an even more compact silicon photonics-based laser assembly

• The company also showcased a CFP2-DCO pluggable

NeoPhotonics unveiled several coherent optical transmission technologies at the OFC conference and exhibition held in San Diego last month.

Ferris Lipscomb“There are two [industry] thrusts going on right now: 400ZR and data centre interconnect pizza boxes going to even higher gigabits per wavelengths,” says Ferris Lipscomb, vice president of marketing at NeoPhotonics.

The 400ZR is an interoperable 400-gigabit coherent interface developed by the Optical Internetworking Forum (OIF).

Optical module makers are developing 400ZR solutions that fit within the client-side QSFP-DD and OSFP pluggable form factors, first samples of which are expected by year-end.

Kim Roberts: The 2019 John Tyndall Award winner

A Profile

A conceptualiser, mathematician, furniture maker, prolific inventor, sushi lover, creative spirit, team leader and mentor. These are just some of the descriptors applied to Kim Roberts of Ciena by the people that know him.

Roberts has been awarded the 2019 John Tyndall Award by The Optical Society (OSA) and the IEEE Photonics Society in recognition of his “pioneering contributions to the development of practical coherent communication systems”.

“It is well deserved,” says Seb Savory, who first knew Roberts when they both worked at Nortel and who is now an academic at the University of Cambridge working on joint projects with Ciena. Ciena acquired Nortel in 2010.

Pilot Photonics makes a one terabit coherent comb source

Pilot Photonics has produced a four-wavelength laser chip for one-terabit coherent transmissions. 

It is one of several applications the Irish start-up is pursuing using its optical comb source that produces multiple tunable outputs, the equivalent of a laser array.   

The company is using its laser technology and photonic integration expertise to address Next Generation Passive Optical Network 2 (NG-PON2), coherent long-haul transmission, and non-telecom applications such as Light Detection and Ranging (LiDAR) and sensing.

“We have a number of chips reaching maturity and we are transitioning from an R&D-focussed company to early commercial activity,” says Frank Smyth, CEO of Pilot Photonics.
