- DWDM transmission systems

- SDH transmission system

- Cable AM television video systems

- Dispersion adjusting

Features:

-Optimized residual dispersion and broadband dispersion compensation in DWDM system

- Slope compensation of G.652 fiber in C-band (Typical)

- Low insertion loss

- Low Polarization Mode Dispersion

- Features Telcordia GR-2854-CORE qualified

- Reliability Telcordia GR-1221-CORE qualified

-Different package styles, connector types and pigtail lengths available

Dispersion Compensation and Dispersion Slop Compensation To compensate dispersion at a specific wavelength, there is following equation:

DTF×LTF +DDCF×LDCF = 0

DTF: the dispersion of the transmission fiber.

LTF: the length of the transmission fiber.

DDCF: the dispersion of the dispersion compensating fiber.

LDCF: the length of the dispersion compensating fiber.

For dispersion slope compensation, there is:

STF×LTF +SDCF×LDCF = 0

STF: the dispersion slope of the transmission fiber.

SDCF: the dispersion slope of the dispersion

compensating fiber.

By combining the above two equations, we have follow equation to get both dispersion anddispersion slope compensation:

RDSDCF = SDCF / DDCF = STF / DTF
