Dispersion is one of the transmission properties of the optical fiber, and the optical pulse signal will be broadened in time after transmission in the optical fiber for a distance, which produces inter-symbol interference, thus increasing the error rate and affecting the quality of communication.

Types of TDCM

01- Tunable Dispersion Compensation Card

Tunable Dispersion Compensation line card uses fiber as the underlying technology to achieve tunability, which allows it to be unlocked from a specific 100/50 GHz grid-like fiber grating and etalon technologies require.

TDCM FAQs

What is dispersion compensation module?

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. A dispersion-compensating module is often placed between two fiber amplifiers.

How can we reduce dispersion?

One way to decrease chromatic dispersion is to narrow the spectral width of the transmitter. Lasers, for example, have a more narrow spectral width than LEDs. A monochromatic laser emits only one wavelength and therefore, does not contribute to chromatic dispersion.

What do you mean by zero dispersion fibers?

A wavelength where the group delay dispersion of a fiber or a material is zero. Categories: general optics, fiber optics and waveguides. Formula symbol: λ0.
