Abstract
Apparatus is disclosed which is advantageously used in local area, metropolitan-area, and wide-area optical networks having a dual bus architecture, permitting significantly increased distance before termination or regeneration of the optical signal. A portion of the received optical signal is tapped from a fiber, converted to an electrical signal, before presentation to a node. That remaining portion of the received optical signal enters a fiber delay line and is amplified by an optical amplifier. Data to be transmitted from a node is converted from an electrical signal to an optical signal and transmitted on the bus.
