Seven-core MC-EDFA pumped with single MM-LD optimized for L-band is developed. Output power of 19 dBm for each core is realized between 1576-1603nm with 33% reduced power consumption.

We find that quasi-phase-matching by periodic insertions of pump-phase-shifters into a highly nonlinear fiber enables parametric gain flat and broad. The insertion of the shifter broadens 0.3-dB gain bandwidth to 30 nm from 9 nm.

Summary form only given. In this report, we will show the result of a basic measurement about an 1530-nm pumped Er-doped fiber amplifier (EDFA). We backward pumped an EDFA at 1533 nm, and measured its gain and noise characteristics.

Erbium-doped fiber amplifier (EDFA) is an indispensable element for AM-FDM optical video distribution systems to allow long transmission distances and branching losses. However, there is a problem of gain tilt of EDFA combined with laser chirp, which
