80km Dispersion Compensation Fiber Pluggable Module
Dispersion occurs when an optical signal travels long distances in an optical fiber, resulting in signal distortion. Dispersion Compensation Fiber (DCF) is a special fiber with a negative chromatic dispersion, which is just the opposite of G.652 fiber and can counteract the effects of chromatic dispersion in G.652. This passive module provides a high level of compensation while maintaining low PMD dispersion as well as low insertion loss and low noise. Passive DCF is a simple, reliable and cost-effective way of compensating for dispersion, allowing signals to travel over 120km without regeneration.

Series QT860
Model QT860-DCM80 | 80km DCM
At first we wanted to buy a QT860-DCM40. Before buying, we asked the customer service staff. After we told him our network environment, QSFPTEK engineers helped us calculate the link loss and some other factors, such as what fiber we used. model. Through their pre-plan, we chose QT860-DCM80, which was of great help to us. If we use DCM40, it will not meet the network requirements we need. Express thanks to QSFPTEK engineers!
