Product Brief

Features

  • ITU grid wavelengths at 100 GHz spacing
  • Low RIN
  • Laser welded, hermetically sealed
  • Built in thermistor and monitor photodiode

Overview

The module is ideal in applications where low relative intensity noise (RIN) and stable polarization-maintaining properties are needed.

The module contains a thermo-electric cooler, thermistor, and monitor detector and is designed and built using EM4’s high reliability platform for defense applications.
