Heavy Reading’s take on optical module trends  

Part 1: Optical transceiver trends 

The industry knows what the next-generation 400-gigabit client-side interfaces will look like but uncertainty remains regarding what form factors to use. So says Simon Stanley who has just authored a report entitled: From 25/100G to 400/600G: A Competitive analysis of Optical Modules and Components.

Implementing the desired 400-gigabit module designs is also technically challenging, presenting 200-gigabit modules with a market opportunity should any slip occur at 400 gigabits.


Simon StanleyStanley, analyst-at-large at Heavy Reading and principal consultant at Earlswood Marketing, points to several notable developments that have taken place in the last year. For 400 gigabits, the first CFP8 modules are now available. There are also numerous suppliers of 100-gigabit QSFP28 modules for the CWDM4 and PSM4 multi-source agreements (MSAs). He also highlights the latest 100-gigabit SFP-DD MSA, and how coherent technology for line-side transmission continues to mature.

Books in 2015 - Final Part 

The final part of what industry figures have been reading in 2015 - Part 3 of 3

Sterling Perring, senior analyst, Heavy Reading  

My ambitions to read far exceed my actual reading output, and because I have such a backlog of books on my reading list, I generally don’t read the latest.

Source: The Age of Spiritual Machines

I have long been fascinated by a graphic from futurist Ray Kurweil which depicts the exponential growth of computing and plots it against living intelligence. The graphic is from Kurzweil’s 1999 book on artificial intelligence The Age of Spiritual Machines: When Computers Exceed Human Intelligence, which I read in 2015.

Optical industry restructuring: The analysts' view

The view that the optical industry is due a shake-up has been aired periodically over the last decade. Yet the industry's structure has remained intact. Now, with the depressed state of the telecom industry, the spectre of impending restructuring is again being raised.

In Part 2, Gazettabyte asked several market research analysts - Heavy Reading's Sterling Perrin, Ovum's Daryl Inniss and Dell'Oro's Jimmy Yu - for their views.

Part II: The analysts' view

"It is just a very slow, grinding process of adjustment; I am not sure that the next five years will be any different to what we've seen"

60-second interview with .... Sterling Perrin

Heavy Reading has published a report Photonic Integration, Super Channels & the March to Terabit Networks. In this 60-second interview, Sterling Perrin, senior analyst at the market research company, talks about the report's findings and the technology's importance for telecom and datacom.


"PICs will be an important part of an ensemble cast, but will not have the starring role. Some may dismiss PICs for this reason, but that would be a mistake – we still need them."

Ciena: Changing bandwidth on the fly

Ciena has announced its latest coherent chipset that will be the foundation for its future optical transmission offerings. The chipset, dubbed WaveLogic 3, will extend the performance of its 100 Gigabit links while introducing transmission flexibility that will trade capacity with reach.

Feature: Beyond 100 Gigabit - Part 1

"We are going to be deployed, [with WaveLogic 3] running live traffic in many customers’ networks by the end of the year"

Michael Adams, Ciena

ROADMs: core role, modest return for component players

Next-generation reconfigurable optical add/ drop multiplexers (ROADMs) will perform an important role in simplifying network operation but optical component vendors making the core component  - the wavelength-selective switch (WSS) - on which such ROADMs will be based should expect a limited return for their efforts.


"[Component suppliers] are going to be under extreme constraints on pricing and cost"
