Technically I agree that they have a lot in common. But I think the large devices, which are often not cylindrical, are usually called light pipes. http://uk.mouser.com/Mobile/Optoelectronics/LED-Indication/LED-Light-Pipes/_/N-b1d20 Some light pipes are hollow inside. I think that is stretching the definition of optical fibre. According to Wikipedia, light pipes or light tubes were originally developed by the ancient Egyptians. Some of these things are hollow are more than 1 m in diameter. I would hardly call that an optical fibre. But call them what you fancy (optical fibre, multi more fibre, waveguide, light tube, light pipe. ...) I think such a device might solve the problem getting the LTE Lite's status LEDs onto a box. I don't have an LTE Lite, but given that they are low power devices, where heat generation is undesirable, I suspect that the light output level might be a bit low. In which case a photodiode or similar may be needed.
