1550nm In-line Faraday Rotator

The 1550nm In-line Faraday Rotator is characterized with low IL, high return loss, high extinction ratio and excellent environmental stability and reliability. It is with fiber in and fiber out. They are ideal for polarization maintaining fiber amplifiers, fiber lasers, and high-speed communication system and instrumentation applications.

Features

  • Low insertion loss
  • Excellent stability and reliability
  • High power handling

Applications

  • Fiber laser
  • Fiber amplifier
  • Communications

  1. Above specifications are for device without connector.
  2. For devices with connectors, IL will be 0.3dB higher, RL will be 5dB lower and ER will be 2dB lower. The default connector key is aligned to slow axis. Power transmits through the connector less than 2W.
  3. Higher power up to 20W is possible; please contact DK Photonics for details.
