Abstract
In an optical fiber telecommunications network for providing both narrowband telephony signals and broadband video services over a single optical fiber using a single optical carrier, an optical distribution shelf includes a plurality of optical distribution units and interface units for interfacing with a controlling microprocessor. The optical distribution units receive baseband TDM telephony signals in serial format and the broadband video signals and function to frequency division multiplex the broadband video signals with the baseband telephony signals. The multiplexed signal is used to frequency modulate an optical carrier for transmission on a single optical fiber.
