Synchronisation Distribution Units

 


OSA 5533c Synchronisation Distribution Unit with Holdover
OSA 5533c Synchronisation Distribution Unit (SDU) The OSA 5533C SDU provides a very economic and reliable solution to the distribution of synchronisation references to network elements, such as switches, cross-connects and multiplexers. The OSA 5533C SDU provides up to 48 outputs referenced to the selected input or to the Holdover Unit. A 1:1 card protection is optionally available for all output cards. With the OSA 5533C SDU it is also possible to re-time up to 24 traffic-carrying signals.

 


OSA 5530b Synchronisation Distribution Unit
OSA 5530b Synchronisation Distribution Unit The Synchronisation Distribution Unit OSA 5530B SDU is designed primarily to extend the output capacity of our synchronisation systems such as OSA 6500B PRC, and OSA 5548B SASE. It can also be used in stand-alone applications where a stable reference is available. The unit provides distribution of synchronisation references to network elements, e.g. switches, cross-connects and multiplexers.

 


OSA 5135c Synchronisation Distribution Unit
OSA 5135 SDU The OSA 5135 Synchronisation Distribution Unit filters and distributes 1 input to 8 outputs individually configurable. It adds a holdover and filtering capability conform to G.812 Type II recommendation. The OSA 5135 Synchronization Distribution Unit incorporates an integrated highly accurate oven-controlled oscillator, which filters the received signal and provides a holdover quality typical of an SSU/BITS during an eventual loss of input signal.
