4x25G Optical Mux Chip on Strip

4X25G CWDM PLC MUX 晶条
The strip of optical multiplexer circuits is based on arrayed waveguide grating technology and silica-on-silicon material system. The circuits are designed and fabricated to meet requirements for Coarse Wavelength Division Multiplexing (CWDM) applications.

Features

  • Strip of optical circuits for CWDM applications
  • AWG based designs
  • Robust, silica-on-silicon material system
  • Compact size for small form factor packaging
  • Pitch =500μm
  • RoHS* Compliant
