Project Description

80um 1550nm Polarization Maintaining Filter Coupler (1×2/2×2)

The 80um 1550nm Polarization Maintaining Filter Coupler is a polarization maintaining coupler which splits the light from the input PM fiber into two output PM fibers. It is made of 80um core RC fiber. The PM Filter Coupler supports the light wave of each polarization to work, without blocking any polarization. The rugged stainless steel package is designed for high optical performance and stability. This compact device offers low excess insertion loss, low back reflection, and high extinction ratio. Split ratios from 1 to 50% are available.

The PM Filter Coupler can be used to split high power linearly polarized light into multiple paths without perturbing the line are state of polarization (SOP).It can also be used as a power tap to monitor signal power in a PM fiber system without disturbing the linear SOP of light propagating in the PM fiber. Applications include PM fiber interferometers, power sharing in polarization sensitive systems, and signal monitoring in PM fiber systems.

If you do not see a standard PM Filter Coupler that meets your needs, we welcome the opportunity to review your desired specification and quote a custom PM Filter Coupler. Requests for custom fiber pigtails, different wavelengths, tap Ratio and handling power of operation or other specific needs will be readily addressed.

  1. above specifications are for device without connector. All parameters are tested at room temperature.
  2. If tap port coupling ratio is ≤ 5%, ER will be 2dB lower; for ≤1% tap port, ER is out of concern.
  3. 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.
