Product Description
Product Description
The Kerns Technology 532nm/633nm 3-Port Circulator is a high-performance passive optical component designed for unidirectional signal transmission (Port 1 → Port 2 → Port 3) while blocking reverse light. Optimized for 532nm/633nm (±5nm bandwidth), it features low insertion loss (1.5dB typical), high isolation (≥20dB), and supports up to 1.2W average power (10kW ns pulse power)—ideal for medical equipment, fiber sensors, and precision optical systems.
Available in PM (polarization-maintaining) or SM (single-mode) fiber types, this circulator uses a compact 38×28×26mm package and operates reliably across +10~+50°C, making it a core component for low-noise, high-stability applications.
Product Features
1. Medical Equipment Compatibility
Supports 532nm/633nm (common wavelengths in medical lasers) and meets low-loss, high-isolation requirements for diagnostic/therapeutic devices.
2. Unidirectional Signal Transmission
Ensures light flows only Port 1→Port 2→Port 3, blocking reverse interference to protect sensitive light sources (e.g., medical laser diodes).
3. High Performance & Low Loss
Typical insertion loss: 1.5dB (max 2.0dB) minimizes signal attenuation in precision systems.
Isolation ≥20dB: Eliminates cross-talk between ports for stable signal transmission.
4. Flexible Fiber & Power Options
Fiber types: PM (extinction ratio ≥20dB) or SM (polarization-dependent loss ≤0.15dB).
Power handling: 0.5W/1.2W average power, 10kW ns pulse power (customizable).
Product Applications
This circulator is widely used in:
Medical Equipment: Signal routing in 532nm/633nm diagnostic lasers (e.g., ophthalmic devices) and therapeutic systems.
Fiber Sensors: Unidirectional signal transmission in 532nm/633nm-based strain/current sensors.
Fiber Amplifiers: Protects amplifier sources from back-reflected light in 532nm/633nm setups.
Test Equipment: Precision signal routing in optical characterization tools.

FAQs
Q1: Why is this circulator suitable for medical equipment?
A1: It supports 532nm/633nm (common in medical lasers), offers low loss (preserves signal strength) and high isolation (prevents source damage)—critical for safe, precise medical devices.
Q2: What’s the difference between PM and SM fiber types?
A2: PM fiber preserves polarization (ideal for polarization-sensitive medical sensors), while SM fiber is cost-effective for non-polarized systems (e.g., basic laser routing).
Q3: How do connectors affect performance?
A3: With connectors, power handling drops to 1W, insertion loss increases by 0.3dB, and extinction ratio decreases by 2dB. Connectors are aligned to the fiber slow axis for minimal impact.
Q4: Can the pulse power be customized?
A4: Yes. The standard peak pulse power is 10kW, but we can design versions with higher power (e.g., 20kW) for specialized medical laser applications.
