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. QMMJ-5HP5-IRVIS-400/430-3AS-2-AR2 Multimode fiber patchcord
Product description
High-power multimode patchcord built on a 400/430 µm, NA 0.22 silica fiber for efficient coupling and stable delivery of visible–near-IR laser power. Designed for low insertion loss and robust handling in laboratory and industrial environments.
Key Features
-
400/430 µm core/cladding, NA 0.22 — wide acceptance angle and forgiving coupling for high-power diode/solid-state sources.
-
High-power connector options (e.g., epoxyless air-gap input; SMA905/FC at output) to mitigate thermal load and back-reflections.
-
Optional VIS/NIR AR coatings to reduce Fresnel losses and boost delivered power.
-
Armored jacket options for improved bend, crush, and tensile resistance.

Handling Notes
Respect the minimum bend radius and avoid shocks near ferrules. Keep end faces clean; during initial alignment start at reduced laser power and increase only after achieving good coupling efficiency, especially with high-power/air-gap inputs.
