ECOC '22 Reflections - Final Part

Gazettabyte has asked industry and academic figures for their thoughts after attending ECOC 2022, held last month in Basel, Switzerland. In particular, what developments and trends they noted, what they learned, and what, if anything, surprised them.

In the final part, Dr. Sanjai Parthasarathi of Coherent, Acacia’s Tom Williams, ADVA’s Jörg-Peter Elbers and Fabio Pittalà of Keysight Technologies share their thoughts.

ADVA targets access with its latest pluggable module

• The 25 gigabit-per-second (Gbps) SFP28 is self-tuning and has a reach of 40km
• ADVA’s CEO, Christoph Glingener, in his plenary talk at ECOC 2022 addressed the unpredictable nature of technology adoption.

ADVA has expanded its portfolio of optical modules with an SFP28 for the access market.

The AccessWave25 is a self-tuning dense wavelength division multiplexing (DWDM) pluggable.

The SFP28 is designed to enable communications service providers to straightforwardly upgrade their access networks from 10Gbps to 25Gbps.

ADVA made the announcement just before ECOC 2022.

ADVA and II-VI’s coherent partnership

• ADVA and II-VI have jointly developed a 100-gigabit coherent DSP
• Both companies plan to use the 2.0-2.5W, 7nm CMOS Steelerton DSP for a 100 ZR QSFP28 module
• II-VI’s ASIC design team engineered the DSP while ADVA developed the silicon photonics-based optics. 

ADVA and II-VI have joined forces to define a tiny coherent digital signal processor (DSP) that fits inside a QSFP28 optical module.

Christoph Glingener

The Steelerton DSP can send a 100-gigabit dense wavelength-division multiplexing (DWDM) transmission over 80-120km, carrying wireless backhaul and access traffic.

“It is backhaul of broadband, it is backhaul of mobile, and it definitely moves outdoors,” says Christoph Glingener, CTO at ADVA.

The module also serves metro networks with its 300km reach using optical amplification.

II-VI and ADVA now join such established coherent players as Ciena, Huawei, Infinera, Nokia as well as Marvell, NEL, and Acacia, now part of Cisco.

Effect Photonics announced at OFC earlier this year its coherent market entry with its acquisition of the Viasat DSP team.

ADVA Optical Engines adds bidirectional multiplexing

• ADVA expands its multiplexing modules to include the network edge
• The company is developing optical modules as part of a three-pillar business strategy
• ADVA’s merger with ADTRAN is approaching its conclusion

ADVA has expanded its family of multiplexing optical modules with a 40km bidirectional design for access networks. 

Saeid Aramideh

Until now, ADVA’s three multiplexer optical module products have focussed on IP routing and switching.

The multiplexing modules combine lower-speed optical interfaces into a higher-speed port.

The company unveiled its 4-by-10-gigabit MicroMux Edge BiDi, its first multiplexer module for the network edge, at the OFC show held in March in San Diego.

Books read in 2021: Part 3

In Part III, two more industry figures pick their reads of the year: Dana Cooperson of Blue Heliotrope Research and ADVA's Gareth Spence. 

Dana Cooperson, Founder and Principal Analyst at Blue Heliotrope Research

My reading traverses different ground from that of other invited analysts to this yearly section. In addition, my ‘avoid new releases’ approach means my picks are not from 2021. And before jumping straight into recommendations, I’ll preface my comments with an homage to communal aspects of reading that have meant so much to me, especially during these two Covid years.

My two book groups managed to meet steadily during the pandemic, sometimes while sitting outside in the snow, covered with blankets and sipping hot tea.

ADTRAN-ADVA's metro-access play

ADTRAN and ADVA have agreed to merge after a long courtship.

The two CEOs have spoken regularly over the years but several developments spurred them to act.

Tom Stanton, ADTRAN CEO

The merger combines ADTRAN’s expertise in access technologies with ADVA’s metro wavelength-division multiplexing (WDM) know-how to create a ‘metro-core-to-door’ company with revenues of $1.2 billion.

As such, the merger promises to double their size and networking skills. Yet the stock market appeared underwhelmed by the announcement, with ADTRAN’s shares down 16% for the rest of the week after the deal was announced. 

Market research analysts, however, are more upbeat.

“ADTRAN and ADVA have a better path forward together than separately,” said John Lively, principal analyst at LightCounting Market Research, in a research note.

The deal is expected to close in the second or third quarter of 2022 but only after several hurdles are overcome in what is described as a complex deal.

ADVA’s 800-gigabit CoreChannel causes a stir

ADVA’s latest addition to its FSP 3000 TeraFlex platform provides 800-gigabit optical transmission. But the announcement has caused a kerfuffle among its optical transport rivals.

ADVA’s TeraFlex platform supports various coherent optical transport sleds, a sled being a pluggable modular unit that customises a platform’s functionality.

Stephan RettenbergerThe coherent sleds use Cisco’s (formerly Acacia Communication’s) AC1200 optical engine. Cisco completed the acquisition of Acacia in March.

The AC1200 comprises a 16nm CMOS Pico coherent digital signal processor (DSP) that supports two wavelengths, each up to 600-gigabit, and two photonic integrated circuits (PICs), for a maximum capacity of 1.2 terabits.

The latest sled from ADVA, dubbed CoreChannel, supports an 800-gigabit stream in a single channel.

ADVA states in its press release that the CoreChannel uses “140 gigabaud (GBd) sub-carrier technology” to deliver 800-gigabit over distances exceeding 1,600km.

This, the company says, improves reach by over 50 per cent compared with state-of-the-art 95GBd symbol rate coherent technologies.

It is these claims that have its rivals reacting.
