Schematically: ________________________ Binary (TTL?) ---->| Line Code Conversion |----> DS3 (B3ZS) | and Pulse Shaping | | | Binary (TTL?) <----| Line Code Conversion |<---- DS3 (B3ZS) | and Clock Recovery | ------------------------ | | DS3 Clock <---------------------- I need this hardware to interface my binary data source/sink to a DS3 fibre optic tranmsission system. This is a prototype digital transmission system, and I am trying to avoid DS3 equipment development. Ideally I would like to obtain a PCB module, but if its a stand-alone piece of hardware (or if a portion of a larger piece of equipment could be made available) I would be interested.
