Sun Hyok Chang, Bong Kyu Kim, Heuk Park, Won Kyoung Lee, and Kwangjoon Kim
Abstract :	Experimental demonstration of bipolar spectral encoding code-division multiple-access with modified pseudorandom noise codes is presented. Bipolar spectral encoding is achieved with an erbium-doped fiber amplifier amplified spontaneous emission source and arrayed waveguide gratings. The bit-error rate performance of 1.25 Gbps signal transmission over 80 km single mode fiber is measured in a multiple-user environment.
Key word :	Access network, optical code-division multiple-access (CDMA), optical fiber communications.
