40KM Passive Dispersion Compensation Pluggable Module


Dispersion Compensation Module (DCM) is designed to fix the form of optical signals that are deformed by chromatic dispersion. The main constituent of DCM is DCF (Dispersion Compensation Fiber) with a negative chromatic dispersion value within the wavelength range between 1525nm and 1565nm. The module offers a high level of compensation while maintaining a low flat insertion loss as well as a low latency. When combined with EDFA and OEO, DCM provides a simple, reliable, and cost-effective long-haul transport solution, making signals go further without regeneration.

DCF-based Module Pushes Limits of Transmission Distance

The pure passive DCM guarantees the normal working after the power failure, supporting high reliability. The excellent DCF (Dispersion Compensation Fiber) can properly correct or reverse the dispersion that was realized as the signal traversed the optical fiber, ensuring long-haul transmission.

Dispersion Compensation  DCF-based Module Pushes Limits of Transmission Distance

Pre-, Post-, and Symmetrical-compensation by Using DCM
Dispersion Compensation Pre-compensation
Pre-compensation

Placing between MUX and BA which provides dispersion compensation before the optical signal of the multiplexing segment entering the transmission line.

Symmetrical-compensation

Placing ahead of LA or between PA and BA which can compensate the optical fiber before each amplifier station.

Dispersion Compensation  Symmetrical-compensation
Dispersion Compensation Post-compensation
Post-compensation

Placing between PA and MUX which can compensate the transmission fiber of the last amplification segment in the multiplexing segment.


Available for All-in-One Multi-Service Transport System

As a part of multi-service transport system, a hot-swappable pluggable DCM card occupies 2 slots in the 1U/2U/4U chassis, which can be highly integrated with FS management platforms and OEO/EDFA/OLP products.

    Questions & Answers
    • Q:

      For 1G and 10G transmission rate, does the dispersion need to be considered? By Humberto on 05/11/2018

      A:

      If your transmission rate is 1G, DCM will not be required. When transmission rate is 10G rate (Whether it is pure 10G rate signal or 1G & 10G mixed rate signal), DCM is required. Additionally, dispersion is also effected by fiber type. For example, the dispersion coefficient of G.652 fiber is 17ps/(nm*km), and G.655 fiber is 4.5ps/(nm*km). By FS on 05/11/2018

    • Q:

      How to know the compensation length for my link? What is the math for that? By Ianthe on 12/06/2017

      A:

      You can use the following method to calculate the compensation length, as a reference to select the DCM you need. The link distance minus the transmission distance of the optical module is the minimum compensation distance, on this basis need to add 20km to ensure enough compensation. For example, if the transmission span is 135km, the compensation length is 75km (135km - 80km + 20km = 75km), which means you can choose a DCM whose compensating length is 80km. By FS on 12/06/2017

    • Q:

      What information should be submitted to locate the accurate DCM? By Elmarthur on 11/16/2017

      A:

      Compensated length, utilized position, insertion loss and type of housing need to be comfirmed. By FS on 11/16/2017
