OTN6500 TDC Tunable Dispersion Compensation Card up to 120km 2100 ps/nm


OTN6500 TDC (tunable dispersion compensator) card is mainly used for dispersion compensation of high-speed transmission systems. It can accurately manage the residual dispersion after segmented fixed optical compensation and provide a flexible and accurate solution for dispersion compensation.

This Tunable Dispersion Compensation Card is 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 systems.

OTN6500 TDC Tunable Dispersion Compensation Card Functional Structure

OTN6500 TDC Tunable Dispersion Compensation Card


  • Adjustable: TDC provides high precision, dynamically adjustable dispersion compensation over a wide range of dispersion value.
  • Low latency: TDC latency is less than 25ns, making it ideal for time-sensitive networks.
  • G.652 slope matching: TDC compensates for the dispersion slope of the fiber, providing accurate and uniform residual dispersion for each channel of the C-band.
  • Multi-channel: TDC has a complete C-band coverage and can be used on 50GHz or 100GHz DWDM networks.
  • The dispersion compensation range is large, and it can be selected from ±800ps/nm to ±1200ps/nm.
  • The optical path is transparent and does not change the optical signal.
  • Simple structure and convenient maintenance.
