Abstract

A widely wavelength-tunable erbium-doped-fiber laser (T-EDFL) located at a central office is proposed for the bidirectional high-speed performance testing of wavelength-division-multiplexing access networks in which injection-locked Fabry-Pérot laser diodes located at optical network units are used for upstream transmissions. The T-EDFL not only generates laser light for downstream transmission testing, but also serves as the injection source for upstream transmission testing. It has a wide tunable range of 64 nm (1540 to 1604 nm), a high output power of 2.2 dBm, and a good signal-to-noise ratio above 46 dB. For 10-Gb/s downstream and 1.25-Gb/s upstream transmissions over a 10-km single-mode fiber (SMF), power penalties at a bit error rate of 10⁻⁹ are less than 0.94 dB and 0.76 dB (1.26 dB and 1.68 dB) for downstream and upstream transmissions at C-band (at L-band) wavelengths, respectively. In the transmissions over a 25-km SMF, the penalties are 2.24 dB and 2.36 dB (3.66 dB and 4.18 dB) at C-band (at L-band) for downstream and upstream transmissions, respectively.
