Product Description

Product Description

The Kerns Technology Multi-band Compatible 780-2050nm Beam Splitter/Combiner is a high-performance polarization-maintaining (PM) optical component designed to split or combine light signals across a wide 780-2050nm wavelength range (covering 850/980/1064/1550/2050nm). It is available in Grade P (premium) and Grade A (standard) configurations, with PM Panda fiber for ports 1&2 and optional SM/PM fiber for port 3.

This component delivers industry-leading performance: typical insertion loss as low as 0.4dB (Grade P), extinction ratio ≥20dB, and 300mW CW power handling. Its compact φ5.5×35mm package, wide operating temperature (-5~+70°C), and flexible fiber/connector options make it ideal for polarization-sensitive systems requiring multi-wavelength compatibility.

Product Features

1. Ultra-Wide Multi-band Coverage

Supports 780-2050nm (including 850/980/1064/1550/2050nm) with tailored wavelength ranges (±10~40nm) — eliminates the need for multiple single-wavelength components.

2. Grade-Tailored Performance

Grade P: Typical insertion loss 0.4~0.6dB, extinction ratio ≥22dB (for high-precision systems)
Grade A: Typical insertion loss 0.5~0.7dB, extinction ratio ≥18dB (for cost-effective setups)

3. High Polarization Preservation

PM Panda fiber (ports 1&2) and optional PM fiber (port 3) ensure stable polarization state transmission, critical for fiber gyroscopes and current sensors.

4. Robust & Flexible Design

300mW CW power handling (1W with connectors)
Compact φ5.5×35mm package for space-constrained systems
Customizable fiber/connector options (SM/PM fiber, FC/SC connectors)

Product Applications

This multi-band PM beam splitter/combiner is widely used in:

Fiber Current Sensors: Splits/combines polarized light for high-precision current measurement across multiple wavelengths.
Fiber Optic Gyroscopes: Preserves polarization to ensure accurate angular velocity detection in navigation systems.
Fiber Sensing Systems: Enables stable signal distribution in multi-wavelength polarization-based sensing setups.
Coherent Telecom Systems: Supports polarization-matched signal combining/splitting in 1550nm-based long-haul links.

FAQs

Q1: What is the advantage of multi-band compatibility?

A1: It supports 780-2050nm in a single component, reducing system complexity and cost compared to using multiple single-wavelength beam splitters/combiners.

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 choose Grade P or A for specific wavelengths?

A3: Yes. Grade P is recommended for high-precision applications (e.g., fiber gyroscopes), while Grade A balances performance and cost for general sensing systems.

Q4: Is port 3 fiber type customizable?

A4: Absolutely. Port 3 can be configured as SM fiber (for non-PM interfaces) or PM Panda fiber (for fully polarized setups) to match your system’s requirements.
