Optical transceivers: Pouring a quart into a pint pot 

Transceiver feature - 3rd and final part

Optical equipment and transceiver makers have much in common.  Both must contend with the challenge of yearly network traffic growth and both are addressing the issue similarly: using faster interfaces, reducing power consumption and making designs more compact and flexible.  

Yet if equipment makers and transceiver vendors share common technical goals, the market challenges they face differ. For optical transceiver vendors, the challenges are particularly complex.

LightCounting's global optical transceiver sales forecast. In 2009 the market was $2.10bn and will rise to $3.42bn in 2013

Differentiation in a market that demands sameness

Transceiver feature: Part 2

At first sight, optical transceiver vendors have little scope for product differentiation. Modules are defined through a multi-source agreement (MSA) and used to transport specified protocols over predefined distances.


“Their attitude is let the big guys kill themselves at 40 and 100 Gig while they beat down costs"

Do multi-source agreements benefit the optical industry?

Transceiver feature: Part 1

System vendors may adore optical transceivers but there is a concern about how multi-source agreements originate. 

Optical transceiver form factors, defined through multi-source agreements (MSAs), benefit equipment vendors by ensuring there are several suppliers to choose from.  No longer must a system vendor develop its own or be locked in with a supplier.


“Personally, the MSA is the worst thing that has happened to the optical industry
