Product Description

Product Description

The Kerns Technology Low Insertion Loss 532nm/633nm Beam Splitter/Combiner is a high-precision PM optical component designed to split or combine 532nm/633nm light signals while preserving polarization state. It adopts PM Panda fiber for ports 1&2 (and optional PM fiber for port 3), ensuring stable polarization performance for sensitive applications.

With typical insertion loss as low as 1.3dB, extinction ratio ≥18dB, and 300mW CW power handling, this component balances low signal attenuation and high polarization integrity. Its compact package, wide temperature range (-5~+70°C), and flexible fiber/connector options make it ideal for high-precision optical sensing and communication systems.

Product Features

1. Dual-Wavelength Compatibility

Supports 532nm/633nm (±15nm range) to match the wavelengths of common lasers used in sensing and gyroscope systems.

2. Low Insertion Loss & High Polarization Preservation

Typical insertion loss: 1.3dB (≤1.5dB max) minimizes signal attenuation
Extinction ratio ≥18dB ensures stable polarization state transmission—critical for PM-sensitive applications.

3. Flexible Fiber Configuration

Ports 1&2: PM Panda fiber (standard)
Port 3: SM fiber or PM Panda fiber (customizable) to adapt to diverse system interfaces.

4. Robust Performance

300mW CW power handling (1W with connectors) meets the demands of low-to-medium power optical systems
High directionality/return loss (≥50dB) reduces signal interference.

Product Applications

This 532nm/633nm PM beam splitter/combiner is widely used in:

Fiber Current Sensors: Splits/combines polarized light to measure current with high precision.
Fiber Optic Gyroscopes: Preserves polarization state to ensure accurate angular velocity detection.
Fiber Sensing Systems: Enables stable signal distribution in polarization-based sensing setups.
Coherent Telecom Systems: Supports polarization-matched signal combining/splitting in high-stability links.

FAQs

Q1: What is the benefit of PM fiber in this component?

A1: PM fiber preserves the input light’s polarization state, which is essential for applications like fiber gyroscopes—where polarization degradation would reduce measurement accuracy.

Q2: How do connectors affect performance?

A2: With connectors, power handling drops to 1W, insertion loss increases by 0.3dB, and extinction ratio decreases by 2dB. We align connectors to the fiber slow axis for minimal polarization impact.

Q3: Can I customize the fiber type for port 3?

A3: Yes. Port 3 can be configured as SM fiber (for non-PM systems) or PM Panda fiber (for fully polarized setups) based on your system requirements.

Q4: Is this component suitable for high-power applications?

A4: It supports 300mW CW power (standard) — ideal for low-to-medium power systems. For higher power needs, we can provide customized high-power PM beam components.
