Oscilloquartz has achieved an industry milestone with the launch of the OSA 5335 Modular Precision Time Protocol (PTP) Grandmaster. This is the first product of its kind to feature a modular design and extreme scalability at the same time. The OSA 5335 can support from 128 to over 3,000 remote PTP clients at 128 packets per second (PPS) - something that has never been done before.
