Tunable Dispersion Compensation Module(TDCM)

DCM, based on Gires -Tournois etalon technology, is widely used in all types of 10Gbps or 40Gbps rate DWDM systems Unification. It makes the optical path transmitted by optical signals different at different wavelengths, resulting in periodic dispersion effects, and at each of the wavelengths. The period can be highly controlled by linear group delay response.
By reasonable setting, the group delay response characteristic of TDCM module can effectively compensate the dispersion problem of DWDM optical communication system signal over long distance optical transmission.

High-speed Optical System

In the non-coherent system of single wave 25~ 40G, the method of adopting DCF and TDCM can solve the dispersion residual problem and ensure the performance of the system.

Dispersion Compensation Emergency Repair Platform
Emergency Repair Platform

In case of the failure of optical cable link, 10G optical system emergency repair platform using TDCM can greatly reduce business interruption time and reduce economic losses .

DWDM Transmission System

TDCM can be used as an urgent adjustment role in 10G DWDM point to point applications when transmission distance is in 160km, total loss is less than 40dB and system capacity is 80G.

Questions & Answers
  • Q:

    What's the Gain Flatness of TDCM? By Denes on 24/10/2018


    Gain flatness is the measure of the variation of gain over a specified frequency range. TDCM has no gain value, and this parameter is for EDFA but not for TDCM. By FS on 24/10/2018

  • Q:

    How should I use your TDCM? What advantages does it have? By Slavin on 18/10/2018


    The TDCM should be used with our FMT chassis (#39214). For 25~40G system, it can well solve the problem of dispersion residual; when the cable link fails, it can greatly shorten the time of business interruption; and TDCM can also make the application of repair platform more flexible.
