TDS
(Timing Distribution System)
Fully Integrated System for Facility-Wide Timing Distribution
Menlo Systems’ Timing Distribution and Synchronization System (TDS) is a solution for the distribution of stable optical frequencies and for the maintenance of synchronization and timing in large scale facilities.
The system is fully integrated and remote controllable.
A mode locked laser is used as the Optical Master Oscillator (OMO) which is synchronized to a low-noise RF oscillator or a cavity stabilized CW laser, to obtain optimum phase noise performance both close to and far away from the carrier.
The signal from the laser is amplified using our Source Distribution Amplifier (SDA), and split up using our fully in-fiber design Splitter Box (SPBox) into the required number of ports.
The pulsed, stable laser signal is then distributed across the facility using our Stabilized Fiber Links (SFL) to remotely synchronize lasers or RF systems with unprecedented overall precision and stability.
Optionally, a drift-free a Pulse-Per-Second (PPS) signal is offered at each system backend with programmable frequency and delay.
With all components such as the laser system, optics parts, electronics, and RF generation manufactured by Menlo Systems the TDS is an all-from-one solution allowing close interaction between user and manufacturer for fast and efficient system integration.
