AbstractR-OADMs are systems that allow the very flexible, remote selection of wavelengths transiting a given intermediate node on a fiber network for dropping and/or adding. They allow access to any of the wavelengths going through a node (or, in more limited R-OADM implementations, access to a set of the transiting wavelengths) for use of the data on the chosen wavelength and the possibility of adding to, or modifying, the data on that wavelength for transmitting it on to the next node(s). They also allow the interconnection of multiple intersecting networks (multiple degree nodes) at the optical level, avoiding the expense and complexity of OEO conversions to achieve the interconnection. The device offers the promise of substantial savings in operations costs, and many operational benefits.
We have been writing about R-OADMs and their coming importance almost since the beginning of the technology. This is the fourth R-OADM report in our Lightwave series. Four years ago, we prepared our first report on R-OADMs - “R-OADMs - the Lightwave under Control.” At the time, very few authors were writing much about R-OADMs. As stated in that report it was, “… a report about a device that did not exist; whose technology was unselected; and whose market was very unclear.”
We followed our first report on this subject with a new discussion a year later with “R-OADMs - Still Here in 2004!” By then a few of the smaller DWDM system vendors had a Reconfigurable Optical Add/Drop Multiplexer (R-OADM) offering, none of the major vendors (90%, or so, of the total market) had yet announced a product. Our next update, a year later, (“R-OADMs - Key to Upgrading the Newly Merged Networks,”) of that report noted, “Every major system vendor has a R-OADM offering, and more are on the way. This is very good timing because the RBOC-IXC mergers of early 2005 will require a great deal of network consolidation, and R-OADMs will be key.”
