We demonstrate a cladding-pumped seven-core erbium-doped fibre amplifier. A developed multimode pump light coupler enables the cladding pump. We measure amplification characteristics of all the seven cores and obtain gain of >14dB, noise figure of <9dB in C-band. Total crosstalk for the centre core is -32.7 dB.
