Asahi Kasei DB-3000 3.0 mm Thick PMMA Bare End-Glow POF
Asahi Kasei DB-3000 3.0mm thick step-index PMMA bare end-glow POF, NA 0.5, 0.20 dB/m, 16mm min bend, 150/1000m roll, for ceiling.
Asahi Kasei DB-3000 is a 3.0 mm thick step-index PMMA bare end-glow fiber, the large-diameter grade used where a single bright end point is needed for ceiling and feature lighting. The thick 3 mm core delivers a strong, bright glow. Note: the provided Asahi grade table lists grades only up to DB-2000 (2.0 mm), so the DB-3000-specific values below come from the product listing and are flagged for verification.
Product Overview
This product is part of our POF fiber optical cable range of step-index PMMA plastic optical fibers and jacketed cables. The values below are taken from the supplier grade table, structure sheet and listing; LED-illuminator parameters (color temperature, input voltage, IP rating) are deliberately excluded because they belong to the light source, not the fiber.
Key Features
- Thick 3.0 mm PMMA core for bright single end points.
- Listing values: NA 0.5, 0.20 dB/m, 16 mm bend.
- 150 m or 1,000 m winding options.
- PMMA core / fluorinated cladding, step-index.
- Suited to ceiling and feature lighting where point size matters.

Applications
Star ceiling and feature lighting, bright end-point decoration, and large-core decorative light guides. Browse the full POF fiber optical cable category for other diameters and jacket options.
Ordering and Customization
Confirm the winding length and illuminator port; the 3 mm core needs a matching light-engine interface. Quote at sales@fevelectronics.com. More answers are on the FAQ page, and you can return to the home page.
FAQ
Is DB-3000 on the grade table?
The provided Asahi table ends at DB-2000 (2.0 mm). DB-3000 3.0 mm values come from the product listing and are flagged for confirmation against the latest Asahi datasheet.
Why is attenuation higher than DB-1000?
The listing quotes 0.20 dB/m for DB-3000 vs 0.16 dB/m for the 1.0 mm grade; confirm the test wavelength before a long-link design.
What is the bend radius?
16 mm per the listing; the thick 3 mm fiber should be routed to avoid sharp kinks.
Why Choose Us
We supply the 3.0 mm DB-3000 with the listing values clearly marked as beyond the shown grade table, so buyers can confirm against the latest Asahi datasheet. Browse the POF category, the FAQ page or the home page.
