Product Details

DCM Dispersion Compensation Device 19" 1U Size for SDH & DWDM Systems

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 size can be mounted easily on 19 and 23-inch cabinet rack.

Product Features

● DWDM system dispersion compensation and broadband low residual dispersion

● G.652 fiber C-band 100% slope compensation (standard value)

● Low insertion loss

● Low polarization mode dispersion

● Performance indicators by Telcordia GR-2854-CORE standard certification

● Reliability by Telcordia GR-1221-CORE standard certification

Product Application

SDH high-speed optical transmission system
DWDM optical transmission system
G.652 Standard single-mode optical fiber long-distance and metropolitan area communication system
