Specifications

40km Dispersion Compensation Fiber Pluggable Module

 

DCM dispersion compensation is a pure passive device, which can perform broadband dispersion slope compensation in C-band for standard single-mode fiber (G.652), and is used in optical transmission systems to repair optical signals distorted by dispersion Compensate for damaged signals, and improve the performance of the optical transmission system, thereby realizing high-speed, large-capacity, and long-distance communication. The dispersion range of QSFPTEK's DCM at 1550nm wavelength can reach -10 to -2100ps/nm and can provide products with special requirements for center wavelength and dispersion.

Applications

Point-to-Point Long-Haul DWDM Solution

 

DCM has wide adoption in distance extension applications to compensate for chromatic dispersion.

 

Product details

Compensate Dispersion for Reliable Signals

 

 


 

Fix Signal Dispersion to Extend Transmission Distance

 

A DCM-based DWDM solution can compensate for dispersion, ensuring

signals are received over a longer transmission distance.

 

 


 

40km DCM for Highly Converged WDM Platform

 

The 40km DCM can be integrated into the QT860 series OTN Chassis Platform and works together

with other QT860 series OTN products such as OLP, EDFA, Transponders, etc.

 

Questions & Answers

more+
  • I didn't see my required DCM distance, can I customize it?
    Yes, you can consult your account manager to confirm your desired distance and connectors. Distract from LC/SC/FC connector, UPC/APC polish, 10-140km distance, and pulg-in module or 1U rack mount housing customize available.
  • What is a DCM and when should I use it?
    DCM stands for Dispersion Compensation Module. It's a device designed to rectify optical signals that have been distorted by dispersion during their transmission. By compensating for signal degradation within optical transmission systems, thereby improving the performance of the optical transmission system (i.e. extending the transmission distance). When you need to increase the transmission distance in your optical transmission link, EDFA paired with DCM would be a good choice.
  • Is this dispersion compensation module a passive product, I don't need to set up a power supply, right?
    Yes, the DCM product is 100% passive, and you don't need to set up power supply.
