Challenges, progress & uncertainties facing the optical component industry

In recent years the industry has moved from direct detection to coherent transmission and has alighted on a flexible ROADM architecture. The result is a new level in optical networking sophistication. OFC/NFOEC 2012 will showcase the progress in these and other areas of industry consensus as well as shining a spotlight on issues less clear.

Optical component players may be forgiven for the odd envious glance towards the semiconductor industry and its well-defined industry dynamics.

The CFP4 optical module to enable Terabit blades

The next-generation CFP modules - the CFP2 and CFP4 - promise to double and double again the number of 100 Gigabit-per-second (Gbps) optical module interfaces on a blade.

Using the CFP4, up to 16, 100Gbps modules will fit on a blade, a total line rate of 1.6 Terabits-per-second (Tbps). With a goal of a 60W total module power budget per blade, that equates to 27Gbps/W. In comparison, the power-efficient SFP+ achieves 10Gbps/W.

Reflections and predictions: 2011 & 2012 - Part 1

Gazettabyte has asked industry analysts, CEOs, executives and commentators to reflect on the last year and comment on developments they most anticipate for 2012.

"For 2012, the macroeconomy is likely to dominate any other developments"

Martin Geddes, telecom consultant @martingeddes

Sometimes the important stuff is slow-burning: we're seeing a continued decline in the traditional network equipment providers, and the rise in Genband, Acme, Sonus and Metaswitch in their place. Smaller, leaner, and more used to serving Tier 2 and Tier 3 operators and enterprise players and their lower cost structures.

100 Gigabit for the metro

ADVA Optical Networking has launched a 100 Gigabit transmission card designed for metro wavelength-division multiplexing (WDM) applications.

The firm claims this is an industry first: a direct-detection-based 100 Gigabit-per-second (Gbps) design using four, 28Gbps channels rather than current 10x10Gbps schemes.

"Data centre operators want to make best use of the fibre insfrastructure and get lower overall cost, footprint and power consumption"

Jörg-Peter Elbers, ADVA Optical Networking

OFC announcements and market trends

Avago Technologies, Finisar and Opnext spoke to Gazettabyte about market trends and their recent OFC/NFOEC announcements. 

More compact transceiver designs at 10, 40 and 100 Gigabit, advancements in reconfigurable optical add-drop multiplexer (ROADM) technology and parallel optical engine developments were all in evidence at this year’s OFC/NFOEC show held in Los Angeles in March.
