The TDC (tunable dispersion compensator) card launched by Sintai Communications is mainly used for dispersion compensation of high-speed transmission system, can accurately manage the residual dispersion after segmented fixed optical compensation, and provide flexible and accurate solution for dispersion compensation. It’s independent, transparent, safe and reliable for optical transmission signals, so as to ensure normal communication of the system. It is suitable for high-speed, long-distance WDM transmission system.

Adjustable: provides highly accurate, dynamically adjustable dispersion compensation over a wide range of dispersion values.
Low Latency: TDC's latency is less than 25ns, making it ideal for time-sensitive networks.
Multi-channel: TDC has full C-band coverage and can be used on 50GHz or 100GHz DWDM networks.
Large dispersion compensation range, supporting ±1400ps/nm.
Optical path is transparent and does not change the optical signal.
Simple structure and easy maintenance.
