Abstract

The passive-access optical ring has long been ignored because, owing to optical-power constraints, it can support only on the order of 10 nodes spanning 10 km. The emergence of the practical optical amplifier raises the possibility of surmounting this limitation, but only if the accompanying amplified spontaneous emission (ASE), recirculating indefinitely around the ring, can be controlled. It is shown that through proper design, the spontaneous emission can be held to very low ( mu W) levels, thus permitting the construction of amplified 2.5 Gb/s ring networks supporting several hundred nodes spanning several hundred kilometers. Applications are expected in high-speed multiaccess data networks and in survivable interoffice facilities.<>
