Abstract: A method for initializing a service unit in a communication system is provided. The method comprises receiving a synchronization signal from a head end at the remote unit, receiving an identifier specifying the remote unit and receiving an upstream frequency band and control channel designation at the remote unit. The frequency band includes a number of subbands with at least one control channel in each subband. The method further comprises tuning to the designated frequency band, transmitting a reference signal on a selected channel to the head end, receiving adjustment signals based on the reference signal transmitted to the head end to allow signals transmitted from the remote unit to be orthogonal at the head end to signals from at least one other remote unit and adjusting parameters at the remote unit based on the adjustment signals.

Abstract: The present invention relates to a fiber optic device for the optically connecting optical fiber. The device consists of fiber optic connectors holding the terminal ends of optical fiber in ferrules and an adapter for receiving fiber optic connectors. The adapter includes a sleeve within a longitudinal opening which aligns the ferrules and the terminal end of the optical fiber held by the ferrules. Within the sleeve is placed an attenuator which extends across the longitudinal opening in the sleeve and is held at an angle to the longitudinal axis of the opening by slots in the sidewall of the sleeve. The angle at which the attenuator is held may be perpendicular or non-perpendicular to the longitudinal axis of the sleeve. The sleeve is further prevented from rotating within the adapter by pockets formed in the inner wall of the longitudinal opening engaging extensions of the attenuator beyond the sidewall of the sleeve.
