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.

Ciena's multi-format 400G coherent QSFP-DD pluggable

Ciena showcased a working 400-gigabit Universal coherent pluggable module at the ECOC 2022 conference and exhibition in Basel, Switzerland.

Ciena is using its WaveLogic 5 Nano coherent digital signal processor (DSP) for the Universal QSFP-DD coherent pluggable module.

"We call it universal because it supports many transmission modes - interoperable and high performance; the most in the industry," says Helen Xenos, senior director of portfolio marketing at Ciena.

The pluggable has custom extended-performance modes and supports three industry formats: the 400ZR interoperable standard, the 400ZR+ multi-source agreement (MSA), and the OpenROADM MSA. (See tables below).

Tencent makes its co-packaged optics move

  • Tencent is the first hyperscaler to announce it is deploying a co-packaged optics switch chip
  • Tencent will use Broadcom’s Humboldt that combines its 25.6-terabit Tomahawk 4 switch chip with four optical engines, each 3.2 terabit-per-second (Tbps)

Part 2: Broadcom's co-packaged optics 

Tencent will use Broadcom’s Tomahawk 4 switch chip co-packaged with optics for its data centres.

“We are now partnered with the hyperscaler to deploy this in a network,” says Manish Mehta, vice president of marketing and operations optical systems division, Broadcom. “This is a huge step for co-packaged optics overall.”

The Chinese hyperscaler will use Broadcom’s 25.6Tbps Tomahawk 4 Humboldt, a hybrid design where half of the chip’s input-output (I/O) is optical and half is the chip’s serialisers-deserialisers (serdes) that connect to pluggable modules on the switch’s front panel.

The significance of 6G

Henning Schulzrinne is known for speaking his mind.

A professor at the Department of Computer Science and the Department of Electrical Engineering at Columbia University, he previously expressed concern regarding what he saw as excessive hype surrounding 5G.

More recently, he has written about 6G, placing the emerging wireless standard in the broader context of societal needs.

"Research, particularly academic research, should be driven by the urgent needs of society, not just supplying patent-protected 'moats' against the competition, whether between companies or nations," he wrote in an introduction to the book, Shaping Future 6G Networks.

Schulzrinne stresses he is not working on 6G standards but has taken part in an early 6G flagship project at the University of Oulu, Finland.

"My expertise is not on the radio; it is system architecture," he says. "We have a lot of interest in my research group on issues such as automation and authentication, not specifically to 6G but to networks."
