Disclosed is an improved optical fiber that employs a novel coating system. When combined with a bend-insensitive glass fiber, the novel coating system according to the present invention yields an optical fiber having exceptionally low losses.

The coating system features (i) a softer primary coating with excellent low-temperature characteristics to protect against microbending in any environment and in the toughest physical situations and, optionally, (ii) a colored secondary coating possessing enhanced color strength and vividness. The secondary coating provides improved ribbon characteristics for structures that are robust, yet easily entered (i.e., separated and stripped).

The optional dual coating is specifically balanced for superior heat stripping in fiber ribbons, with virtually no residue left behind on the glass. This facilitates fast splicing and terminations. The improved coating system provides optical fibers that offer significant advantages for deployment in most, if not all, fiber-to-the-premises (FTTx) systems.

A laminate panel especially well suited to help form an overhead stowage bin door on an aircraft, wherein the door includes a portion of a high contrast color advertising mural or message integrally formed therewith. The door includes a honeycomb support layer on which at least one fiberglass pre-preg layer is formed. A polyvinyl fluoride (PVF) film is used as a substrate for the color mural or message. A ultraviolet (UV) curable ink is deposited directly on the PVF film via an ink jet printing process that produces a high color density, high color contrast image. The PVF film in one form is a Tedlar® PVF film. The ink is cured virtually immediately after it is deposited on the PVF film. An additional layer of PVF film is then secured to a side of the printed-on PVF film opposite to that on which the ink is deposited via a layer of embossing resin to form the laminate panel. The laminate panel is then secured via a suitable adhesive to the fiberglass pre-preg and honeycomb support layer in a subsequent manufacturing step. The stowage bin door and process of making same enable a portion of a high color density, high contrast image, advertising mural or message to be integrally formed with the door.
