A high-gain and low-noise-figure (NF) erbium-doped fiber amplifier (EDFA) was demonstrated utilizing a new technique called the dual-stage quadruple pass (DSQP) with filters. An efficient amplification occurs at the signal wavelength of 1550 nm when it travels along the DSQP amplifier. The highest gain of 62.56 dB with a low noise figure of 3.98 dB was achieved for an input signal power of -50 dBm and pump powers of 10 and 165 mW in the second and first stage amplifiers respectively.
Key words: EDFA, gain, dual stage quadruple pass (DSQP)
