Asahi Kasei DB-750 / DB-1000 PMMA Plastic Optical Fiber, 0.75 mm & 1.0 mm Bare POF for Decoration Lighting
Asahi Kasei DB-750 (0.75 mm) and DB-1000 (1.0 mm) are step-index PMMA plastic optical fibers supplied as bare end-glow POF reels for decoration lighting, star ceilings, light curtains and short signal links. The product in this group is the Asahi Kasei POF bare fiber itself, not an LED light engine; luminous or color-temperature figures found in supplier listings belong to the illuminator and are not fiber specifications.
Product Overview
DB-750 and DB-1000 belong to the Asahi Kasei PMMA (polymethyl methacrylate) plastic optical fiber family. Light travels by total internal reflection through a transparent PMMA core surrounded by a lower-index fluorinated polymer cladding, which is the standard step-index POF structure. The 0.75 mm DB-750 grade is chosen where a fine, flexible end-glow point is needed, while the 1.0 mm DB-1000 grade carries more light and is easier to handle on reels. We supply these fibers by the reel and can cut to the lengths required by your lighting design. Browse the full range on our POF fiber optical cable category page.
Key Features
- Recognized Asahi Kasei POF grades: DB-750 = 0.75 mm, DB-1000 = 1.0 mm, with NA 0.5.
- Step-index PMMA core / fluorinated cladding for visible-light end glow.
- Flexible and unpowered at the outlet: the fiber itself carries light only, no electricity or heat at the glowing end.
- Reel supply with typical winding lengths of 3,000 m (DB-750) and 1,500 / 5,250 m (DB-1000).
- Optional black flame-retardant jacket for side-light suppression where required.

Applications
Typical uses include end-glow decorative lighting, star ceilings, optical fiber curtains and falling-water effects, hotel / KTV / bar feature lighting, home textiles, and short visible-light signal or sensor links. Pair the fiber with a compatible LED fiber illuminator on the source end. If you are selecting the connector side of a large-core link, see our SMA905 high-power fiber optic connector and industrial Sumitomo H-PCF jumper options.
Ordering and Customization
Please tell us the grade (DB-750 0.75 mm or DB-1000 1.0 mm), required length, whether you need bare or black-jacketed fiber, and the connector / illuminator interface you intend to use. We do not list fixed pricing online; request a quote at sales@fevelectronics.com. More answers are on our FAQ for H-PCF and POF fiber assemblies, and you can return to the home page any time.
FAQ
What is the difference between DB-750 and DB-1000?
They are the same Asahi Kasei PMMA step-index POF family in different core diameters: 0.75 mm and 1.0 mm. DB-750 is thinner and more flexible for fine end-glow points; DB-1000 passes more light and tolerates a larger minimum bend radius (20 mm vs 10 mm).
Is the 6000K color temperature or input voltage part of the fiber?
No. Those parameters describe the LED illuminator / light source, not the PMMA fiber. The fiber only transmits light; its own relevant values are core diameter, NA, attenuation and bend radius.
Can you cut the fiber to a custom length?
Yes. We supply by the reel and can cut to order. Contact us with the grade and total length you need.
Why Choose Us
We supply industrial and lighting-grade POF as recognized by grade number, keep the Asahi Kasei structure data traceable, and quote the fiber honestly rather than mixing light-engine specifications into the product page. Start from the home page or the POF category to explore related products.
