HP Fiber Optic Patchcord 400/430, 0.22 NA
This high-power fiber optic cable features a 400 μm / 0.22 NA fiber, SMA connectors, and a visible anti-reflection (AR) coating. With a length of 2 m, it can handle power levels above 50 W without requiring heat sinking due to the air-gap SMA connector. RVI S-400/430-3AS-1, NA=0.37, SMA Multimode fiber patchcord
Product description
High-power multimode patchcord with a 400/430 µm silica fiber and 0.22 NA for efficient coupling and stable delivery of visible–near-IR laser power. Engineered for low insertion loss and robust handling in laboratory and industrial environments.
Key Features
-
400/430 µm core/cladding, NA 0.22 — supports higher coupling tolerance and larger spot sizes for high-power diode/solid-state sources.
-
High-power connector options (e.g., epoxyless air-gap input; SMA905/FC output) to mitigate thermal load and back-reflections.
-
Optional VIS/NIR AR coatings to reduce Fresnel losses and increase delivered power.
-
Rugged jacket for improved bend, crush, and tensile resistance.
Applications
High-power beam delivery, pilot materials processing, illumination, and test setups requiring a durable, wide-acceptance multimode fiber path.

Handling Notes
Respect the minimum bend radius and avoid shocks near the ferrules. Keep end faces clean; begin alignment at reduced power and increase only after achieving good coupling efficiency (especially with air-gap inputs).
