Del Lighting offers several different types of fiber optic cable made from pMMA (polymethyl methacrylate) “acrylic” fiber. We don’t offer glass fiber because its so hard to work with; it doesn’t bend well and is hard to prepare a harness. Most of our cable is made up of various amounts of 0.75mm (0.03”) cable. For instance, our E-S50 cable has 50 of the 0.75mm fiber optic cables inside a black PVC jacket
Solid core cable is also made up of pMMA acrylic but it has different characteristics. It is somewhat like a plastic jello inside of a harder plastic tube. It is much harder to bend than the stranded cable and, while it is brighter in cross section, you lose light output because less cables can go into a harness. For example. the X20-75 illuminator can handle 15 runs of the E-S50 cable, but only 12 of the SCE-6 solid core cable.
