Flexible Modulation or Flexible Bandwidth, Which One Comes First?

Thursday, March 24, 2016
1:00 PM - 3:00 PM

Event type: Panel

Room number: Room 303B

Organizer:

Joerg-Peter Elbers, ADVA Optical Networking SE, Germany and Gernot Goeger, Huawei, Germany



Description:

Flexible grid ROADMs and bandwidth-variable transponders will furnish optical transport networks with unprecedented levels of flexibility. Programmable ROADMs allow bandwidth management with sub-50 GHz granularity. Future bandwidth-variable transponders may use adaptive modulation as well as adaptive and sliceable optical bandwidth. Thereby network utilization can be optimized by simultaneous consideration of spectral usage and reach. Currently flexible modulation transponders and super-channels are on the verge of commercialization. However, both technologies come at the expense of additional equipment cost and operational complexity. This panel addresses decisive criteria for the choice of the network upgrade path:

  • How do network benefits contrast with increasing equipment cost?

  • How can the operational complexity of flexibility best be handled?

  • What are the challenges in transceiver and ROADM design?

  • Will flexible modulation or flexible bandwidth technologies first be used in commercial networks?
