Chromatic Dispersion Compensation Using Symmetric Extension based Guard Interval in Optical Fast-OFDM

Not Accessible

Your library or personal account may give you access


We propose symmetric extension based guard interval (GI) to enable CD compensation with one-tap equalizers after discrete-cosine transform in optical fast-OFDM, and experimentally demonstrate 20Gbit/s 4-ASK transmission over 124km field-installed SMF with varied GI length.
