JDSU launching ROADM and tunable XFP products for agile optical networks

Optoelectronic chip and module maker JDSU of Milpitas, CA, USA is to continue to expand its family of reconfigurable optical add/drop multiplexer (ROADM) and tunable XFP optical products to increase the capabilities of agile optical networks (AONs) by introducing a series of new devices for network equipment manufacturers (NEMs) over the next six months.

“Bandwidth capacity requirements continue to increase, requiring a great degree of flexibility in the network,” says Craig Iwata, senior director of marketing for JDSU’s Communication & Commercial Optical Products (CCOP) business segment. “To support this level of agility, all of the components within an optical network must also be agile,” he adds. “We’ve collaborated with our customers on a mix of new products that will help them get the most agility out of every network node in the most cost efficient way possible.”

As businesses and consumers use more on-demand applications such as video, increasing volumes of network traffic are entering networks in unpredictable ways, says JDSU. NEMs and service providers are evolving their networks to more sophisticated architectures that can flexibly support this traffic.

New products from JDSU will enable colorless and directionless architectures, enabling any add/drop port to be switched to any degree in the ROADM node.

ROADMs add, drop, and switch wavelengths within an agile optical network. New ROADM products to be introduced over the next six months (tailored to meet various requirements) include the following:

  • Mini 50GHz High Port Count WSS — offering an increased port count of 23 ports with the same size and performance as the 1x9 Mini 50 WSS, enabling increased cost efficiencies in a compact form factor for applications requiring high numbers of add/drop ports and colorless and directionless applications;
  • Mini 100GHz Low Port Count WSS — 1X2 and 1X4 WSSs designed to provide high performance but lower cost points for smaller-sized 100GHz applications;
  • Mini 50GHz Low Port Count WSS – offering 1X2 and 1X4 WSSs designed for high performance at lower cost points for smaller-sized 50GHz applications.

Tunable XFP transceivers (for sending and receiving signals within agile optical networks) provide a dramatically smaller, pluggable and cost-effective solution compared to older transceiver products, and are transforming available fixed XFP ports into tunable interfaces, says JDSU. New tunable XFP products will provide performance enhancements, and include the following:

  • Linear Tunable XFP+ Transceiver — providing an extended reach of 200km and enhanced tolerance to fiber impairments;
  • Enhanced Tunable XFP Transceiver — providing increased power for metro and regional applications and improved optical signal-to-noise ratio (OSNR) performance; and
  • Zero Chirp Tunable XFP Transceiver — designed to support long-haul applications.

The new products, as well as JDSU’s entire AON portfolio, are on show at this week’s Optical Fiber Communication Conference & Exposition and National Fiber Optic Engineers Conference (OFC/NFOEC 2010) in San Diego, CA, USA (23–25 March).
