The JDSU agile optical switch family provides the broadest portfolio of reconfigurable optical add-drop multiplexer (ROADM) solutions designed to meet the requirements of all major market segments and applications. They are the core building blocks for agile optical networks (AONs) and provide the flexibility to remotely reconfigure any or all wavelengths, thereby reducing time-to-service, simplifying networks, and streamlining planning and inventory management. This results in significant Opex and Capex reductions and faster time to revenue.

The wavelength selective switch (WSS) is an N-port module composed of a hermetically sealed optics block with control electronics. The optics block is based on the highly successful free space optics platform in conjunction with a switching engine composed of an array of micro-electromechanical mirrors (MEMS) to provide the functionality and performance required in today’s dynamic networks.

The WSS is used to dynamically attenuate, block switch and route wavelengths independently. Any wavelength/wavelengths can be routed from any port/ports to any other port/ports in any order, resulting in a colorless solution that is highly flexible and requires no pre-planning.

The Mini 50 WSS, based on the highly scalable compact form factor Mini platform offers excellent optical performance and reliability, and represents the next generation of the thousands of JDSU classic 50 GHz solutions that have been deployed in networks worldwide since 2003. These switches have a proven and demonstrated capability to route and manage optical networks, and are currently the only 50 GHz WSSs supporting 100 G live traffic today. In addition to being 100 G-ready, the Mini 50 comes in a reduced height, smaller form factor package with an increased number of ports, and improved optical performance to support ever-increasing applications and requirements. Tested at the JDSU ONR labs at 40 G, the Mini 50 demonstrates >16 node cascadability with minimal OSNR penalty, with projected casacadability up to 26 nodes.

The Mini 50 WSS provides excellent optical performance, proven 40/100 G capability in a compact form factor device and is fully qualified to meet and exceed Telecordia  requirements.
