Obtaining a 1 Pulse Per Second (1PPS) signal is essential for delivering latency and jitter sensitive applications over a packet network through pluggable optics based on a disaggregated solution that may be applicable to service provider (SP) routing and/or server products for various applications. Techniques are presented herein that enable a 1PPS signal to be provided from a network router to an enhanced Small Form Factor Pluggable (SFP+) device by re-purposing an existing pin of an SFP+ connector for the SFP+ device.
