The Ericsson RSU-12 fiber holders (model 42SM045 R1 8R) are precision alignment components engineered for the Ericsson RSU-12 fusion splicer. These holders position optical fibers with micron-level accuracy during the splicing process, enabling consistent low-loss joints across single and multi-fiber configurations. The design accommodates single-mode, multimode, dispersion-shifted, and non-zero dispersion-shifted fibers in both standard and ribbon geometries.

– Compatibility & Integration
These holders function as integral components of the Ericsson RSU-12 fusion splicer platform. The RSU-12 system delivers splice cycles in less than 40 seconds, incorporating integrated heating for rapid sleeve shrink and a large-view color monitor for process visualization. Associated accessories including ultrasonic cleaners and fiber ribbonizers complement the splicing workflow.
