• Exceptional optical isolation with options exceeding 50 dB for dual-stage models.
• Low insertion loss of less than 0.6 dB, ensuring efficient signal transmission.
• Versatile wavelength compatibility spanning 850 nm to 2000 nm.
• Customizable configurations, including fiber type, pigtail diameter, and housing dimensions.

General Description

The in-line isolators offered by Photonics of Crystals (POC) are cutting-edge devices designed to provide optical isolation via fiber optic coupling. These devices are essential for preventing unwanted back reflections and scattered light, enhancing system performance and stability.

POC in-line isolators are available in two primary types:

1. Non-Polarization-Maintaining In-Line Isolators: Ideal for general optical systems, featuring components such as birefringent crystals, Faraday rotators, and collimators to deliver high isolation.
2. Polarization-Maintaining In-Line Isolators: Designed for systems requiring the preservation of polarization states, utilizing polarizers and half-wave plates for steady transmittance.

With a robust design capable of handling high power, minimal insertion loss, and a wide wavelength range, POC in-line isolators excel in applications such as DWDM systems, optical coherence detection, and fiber communications. These isolators are built for durability and environmental stability, ensuring long-term reliability even in demanding conditions.

General Applications and Examples

1. EDFA (Erbium-Doped Fiber Amplifiers):
   In-line isolators are integral components in EDFA setups, enhancing amplification efficiency by eliminating feedback and preventing system instabilities caused by reflected light.
2. DWDM Systems (Dense Wavelength Division Multiplexing):
   POC isolators support high-density data transmission by ensuring signal isolation across multiple wavelengths, boosting system throughput and reducing cross-channel interference.
3. Optical Coherence Detection:
   These isolators improve the precision of coherence-based measurements, such as OCT (Optical Coherence Tomography), by suppressing noise and unwanted reflections in the optical path.
4. Laser Sensing and Fiber Communication:
   POC isolators are critical in ensuring accurate data transmission in sensing and telecommunication systems, delivering clean, reliable signals over extended distances.
