What Is Dispersion Compensation Fiber
Dispersion Compensation Module (DCM) is designed to fix the form of optical signals that are deformed by chromatic dispersion. The main constituent of DCM fiberis DCF (Dispersion Compensation Fiber) with a negative chromatic dispersion value within the wavelength range between 1525nm and 1565nm.
Types of DCMOptical
01- 20km Dispersion Compensation in Optical Fiber
Dispersion Compensation Module (DCM) is designed to fix the form of optical signals that are deformed by chromatic dispersion.
02- 40km DCFDispersion Compensating Fiber
In optical fiber communications, optical dispersion compensationmodules (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 Negative Dispersion 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).
How does dispersion compensating fiber work?
A short length of dispersion-compensating fiber is spliced into a longer length of standard fiber to compensate for dispersion, as in the example below. Dispersion can cause various penalties in signal transmission in optical communications systems.
How can optical fiber dispersion compensationbe overcome?
One way to reduce modal dispersion is to use graded-index fiber. Unlike the two distinct materials in a step-index fiber, the graded-index fiber's cladding is doped so that the refractive index gradually decreases over many layers.
