Introduction

Overview:

To date, a great deal of research and subsequent product development in the optical networking area has focused on the fundamentals of providing long distance, high-capacity transport technology. This work has resulted in the startling advancements in DWDM, CWDM, optical switching, high-capacity routers, new specialized fibers, optical amplifiers and other supporting hardware and software. In just two years, the focus has turned to more efficient ways to use the capacity and capabilities made possible by all of this development. Broadly speaking, we can characterize this new effort as 'Control,' and that control will be all important, because of its impact on operations costs.

This is an update of an earlier report on the same subject from IGI. The previous report was entitled "R-OADMs - The Lightwave Under Control." This report contains completely new forecast material, expanded technical material and updates on deployment activities since the previous work. It also includes new material on Wavelength Selective Switches, and many more figures, explaining the various types of approaches available for R-OADMS. This is a completely stand-alone report, containing all of the background material from the earlier report.

In preparing this update, the author spoke with executive representatives of the major vendors in this area and had input from major prospective users. This input was used to sharpen the focus of the forecasts from the previous report. that input was also used to improve the scenario that was the basis of our forecast.

While the telecom depression has eliminated (or at least dramatically postponed) a number of promised technologies and devices, the R-OADM is still clearly in the telecom future. It has the advantage of being an operations cost saver, and as such will endure when other enhancements may not. Indeed, the flexibility offered by the R-OADM is desire by all network operators. The only impediment is determining how to begin deployment.

This newest report from the Lightwave Series, "R-OADMs - Still Growing in 2004!" is the definitive report on Reconfigurable Optical Add Drop Multiplexers (R-OADMs). These devices are finally going to answer all carriers' desires to be able to control optical domain networks with the same flexibility and ease, as they are familiar with in SONET oriented networks. R-OADMs will provide all of the capacity of wavelength engineering with the ease and familiarity of SONET! These devices will usher in the truly intelligent optical network era.

R-OADMs will be systems that allow the very flexible, remote selection of wavelengths transiting a given intermediate node on a fiber network for drop and/or adding.

They will allow access to any of the wavelengths going through a given node.
They will allow the use of the data on the chosen wavelength and possibly adding to or modifying the data on that wavelength for transmitting on to the next node(s).
All of this can be done without impacting the through wavelengths in any way.

The market forecasts included in the report are very comprehensive, including various types of R-OADMs, as well as forecasts for the major sub-systems and components of R-OADMs. Both US and Global forecasts are provided and units as well as market totals are included. All of theses forecasts are based on discussions with industry participants as well as on the author's extensive experience in the industry. A comprehensive model for development (a time schedule for significant events) of the R-OADM market is the prime driver of the forecasts. This model is explained in detail in the report

This report covers all aspects of this rapidly developing product line. Included are:

Full description of the R-OADM and its relationship to other network elements.
Detailed analysis of the application possibilities for R-OADMs
Discussion of all the technologies and architectures being considered for implementing R-OADMs. (Switch based, Broadcast, and WSS)
Discussion and analysis of the market drivers for R-OADMs.
A detailed model for the market development of R-OADMs, with input from major carriers and vendors.
Detailed US and Global forecasts for R-OADM markets, both on a unit basis and a dollar basis.
Forecasts for US and Global components resulting from R-OADM development and deployment.
Sensitivity analysis for market forecasts.
Listing and discussion of the major vendors involved in R-OADMs both at the component and system level.
A compilation of which vendors are following each of the candidate architectures.
All sections are profusely illustrated with original drawings, tables, and charts.
