Ultra-miniaturized Dispersion Compensating Fibre Module

In the applications of optical fibre communication and fibre laser, dispersion management is an important means to control optical parameters such as pulse and nonlinear. The ultra-miniaturized dispersion compensation fibre module(SDCM) can compensate the dispersion and dispersion slope at C-band for standard single-mode fiber(G.652) and the system residual dispersion is optimized.
Applications
  • Long-haul telecommunication systems with standard single-mode fiber (G.652)
  • DWDM transmission systems
  • SDH transmission system
  • Cable AM television video systems
  • Dispersion adjusting
Characteristics
  • 100% slope compensation of G.652 fiber in C-band (Typical)
  • Optimized residual dispersion
  • Broadband dispersion compensation in DWDM system
  • Low insertion loss
  • Low Polarization Mode Dispersion
  • Small package
  • Meet or exceed Telcordia GR-2854-CORE specification
  • Meet or exceed Telcordia GR-21221-CORE specification
  • Different package styles, connector types and pigtail lengths are available
