Abstract :
Nonregenerative photonic dual buses with passive optical access and optical amplification are investigated for transmission performance and potential network space for MAN/WAN. A two-wavelength system is proposed to improve the network capability, with one wavelength transmitted by the head of bus for distributing the clock and regulating the amplified spontaneous emission. The second wavelength is used by all nodes for network operations. It is shown that a multigigabit photonic dual bus with 100 nodes spanning hundreds of kilometers is possible. Major advantages of such networks are improved flexibility, reliability, uninterruptive maintenance, and graceful upgrade.<>
