Product Description

DCM Dispersion Compensation Module

The DCM dispersion compensation module is a pure passive device designed to compensate the dispersion slope of standard single-mode optical fiber (G.652) in the C-band. It effectively repairs optical signals distorted by dispersion, ensuring high-speed, large-capacity, and long-distance communication.

Key Advantages

  • ✅ High-Performance Compensation: Dispersion range from -10 to -2100ps/nm at 1550nm.
  • ✅ Passive Reliability: Purely passive design for stable, maintenance-free operation.
  • ✅ Customizable: Supports specific requirements for central wavelength and dispersion.
  • ✅ Industry Standards: Conforms to Telcordia GR-2854 and GR1221 standards.
📦 Packaging: 7209/2901 1RU (442 x 250 x 44 mm)
🔌 Interface: LC/UPC (Customizable)
🌡️ Working Temp: -5°C to 70°C
