  1. Multicore EDFA for DWDM Transmission in Full C-bandYukihiro. etc. 张浩 0120349007

  2. space division multiplexing (SDM) multicore fiber (MCF) beyond 100 Tbit/s in one fiber over length of several tens of km demultiplexer at span boundary and each signal was amplified by independent amplifier.

  3. multicore erbium-doped fiber amplifiers (MC-EDFAs) • cladding pumping • one multimode LD utilizing double-cladding structure, leading to low power consumption, lower cost, and downsizing. • optimizing the pump combiner, differential core gain, and noise figure as a future issue. • core pumping • flexibly control the gain in each core individually • utilizing bidirectional core pumping scheme with external gain equalizers • 177 Pbit/s x km per fiber was achieved. • flat gain bandwidth of 16 nm in WDM signals.

  4. preliminary requirements for MC-EDFA First of all, we study the optical characteristics required for MC-EDFA no matter what pumping scheme is used. the same gain properties compared to the conventional EDFA. realize the gain uniformity of the core differential. obtain the low crosstalk between cores. MC-EDFA with core pumping has a merit at this stage

  5. 100GHz-spaced DWDM signals with 48 channels for 7 cores

  6. crosstalk

  7. THANKS!
