delay ripple
The effect of the group delay ripple of the fiber grating is also investigated in the recirculating systems, and it is shown that the transmission distance is limited to 4 cycles (4×167.1km) in the loop with the power penalty fluctuation below 1.0dB.
      
Thus the group delay ripple should be reduced to allow for the wavelength drift of ±5GHz.
      
We describe the theory of the group delay ripple (GDR) generated by apodized chirped fiber gratings using the analogy between noisy gratings and superstructure Bragg gratings.
      
Dispersion compensator imperfections, such as multi-path interference, group delay ripple, insertion loss ripple and limited per-channel compensation bandwidth, place additional limitations on the achievable transmission distance and capacity.
      
In the second section we describe the techniques used to fabricate high performance dispersion compensation gratings as well as the theory of the primary defect of fiber grating dispersion compensation: group delay ripple (GDR).
      
It is determined that a fiber link length of ~80 km can balance the requirements of group delay ripple impact and bandwidth.
      
An all-pass is used for group delay ripple equalization caused by the WDF filters.
      
Another critical issue in ROADM design is the filter shape; both its bandwidth shape and group delay ripple must be considered.
      
Good out-of-band sidelobe suppression of 27 dB and group-delay ripple of 9.5 ps is achieved for fully apodized grating devices.
      
Only a very tiny amount of spurious ripple is acceptable in filters with stringent amplitude ripple and group delay ripple specs.
      
This paper reviews progress in the understanding, measurement, and reduction of group delay ripple in chirped fiber Bragg gratings.
      
The clear line in the GDR graphs is the local standard deviation of the group delay ripple calculated over a 1 nm bandwidth.
      
Use of the interstage filter may result in an increase of the group delay ripple at the baseband outputs.
