The optical coupler includes a scrambler rod which is rectangular in cross section and employs solid substantially inflexible side arms which are also rectangular in cross section. The side arms include a mirrored prism to bend the light path and permit separation of the ends of the distribution side arms so that flexible fiber bundles may be attached to the ends of the distribution side arms.Other References
