Abstract :
We have developed a 19-SDM transmission system consisting of a new low-crosstalk 19-core fiber and a prototype 19-core EDFA. The EDFA uses shared free-space optics to couple pump light into cores and thus is SDM transparent. Recirculating loop experiment with PDM-QPSK signals shows the system feasibility for long-haul transmission over 900 km.
