Dispersion Compensation Unit (G.652)


  • Low insertion loss
  • Low PMD
  • Robust and compact package


  • High speed transmission systems
  • Long-haul telecommunication systems

GIP Technology Dispersion Compensation Modules (DCMs) are designed to compensate the dispersion of conventional G.652 fiber or other transmission fibers having a positive dispersion that occurs in long-haul optical transmission systems. These products offer superior polarization mode dispersion (PMD) performance and a negative dispersion slope, allowing a DWDM or long-haul system to maintain signal integrity over great distances.

Low insertion loss and PMD make the product ideal for long-haul telecommunication systems as well as DWDM transport.

The compact 1U mountable unit serves the area size and can be, easily, embedded in the EIA 19 and 23-inch cabinet rack.
