12-Core Erbium/Ytterbium-Doped Fiber Amplifier for 200G/400G Long-Haul, Metro-Regional, DCI Transmission Applications with ROADM
Résumé
A 12-core Er/Yb-doped fiber amplifier with 21-dBm output power per core and 5.3-Watts
multimode pump is used here to address various transmission applications with ROADM. 1200-km with 200G DP-QPSK and 300-km with 400G DP-16QAM are achieved in serial configuration at 1550-nm. Parallel 12x100-km transport with 400-ZR+ transceiver is also implemented.
