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.

 

Types of DCM

20km Dispersion Compensation Fiber

01- 20km Dispersion Compensation Fiber

Dispersion Compensation Module (DCM) is designed to fix the form of optical signals that are deformed by chromatic dispersion.

 

02- 40km Dispersion Compensation Fiber

in optical fiber communications, dispersion compensation modules (DCM) (also called dispersion compensation units, DCU) can be used for compensating the chromatic dispersion of, e.g., a long span of transmission fiber.

 

03- 60km Dispersion Compensation Fiber

DCF model is a negative dispersion, which is a new type of single-mode optical fiber designed for presently laid G.652& G.655standard single-mode optical fiber.

 

04- 80km Dispersion Compensation Fiber

Dispersion compensation modules are available for any dispersion values from 10km to 140km compensation distance for protocol transparent data rates between 10Mbps and 40Gbps.

 

05- 100km Dispersion Compensation Fiber

the modules are based on mature and reliable optical fiber technology with excellent performance for the optical transmission systems.

DCM FAQs

What are Dispersion Compensating Fibers?

Compensation of dispersion at a wavelength around 1550nm in a 1310nm optimized single-mode fiber can be achieved by specially designed fibers whose dispersion coefficient (D) is negative and large at 1550nm. these types of fibers are known as Dispersion Compensating Fibers (DCFs).
