Abstract: A method and apparatus is presented for reducing or eliminating pathological data patterns from signals for transmission over optical communications systems. One embodiment includes a decoder/deserializer configured to receive an encoded serial digital signal, a ditherer configured to dither a least significant bit of each digital data word, and a reserializer/encoder configured to serialize digital data and encode it, for example according to an applicable communication standard such as SMPTE 259M. The improvements may be provided in a single removable unit, such as a small form-factor pluggable (SFP) module compatible with existing optical communications equipment.

Abstract: A pluggable synchronization clock comprising: a pluggable transceiver and a system clock synchronization subsystem embodied within the pluggable transceiver. The system clock synchronization subsystem may be adapted to implement a packet based precision time protocol. The system clock synchronization subsystem may be further adapted to include a time stamp unit capable of adding a time stamp to a frame using hardware or software.
