- Abstract
- We demonstrate a field trial of the 40 Gb/s single-channel electrical time-division multiplexing (ETDM) prototype by using KT’s installed single-mode fiber (SMF). The prototype consists of a 40-Gb/s optical transmitter, receiver, and four sets of optical amplifiers. In order to provide a practical and economical field trial, we adopt conventional erbium-doped fiber amplifiers (EDFAs) and precise dispersion compensation technology. We obtain the power penalties of 0.5 dB for 10 Gb/s tributary channels after transmission of 219 km.
