Abstract (in Japanese) (See Japanese page) 
(in English) Multi-core fiber (MCF) that has plurality of cores in one fiber is one of the promising candidates to cope with exponentially increasing transmission capacity. To achieve practical use of it, a fan-out which allows each core of MCF to be connected into individual single core fibers is essential. In the previous paper, we reported a development about the fan-out with 45μm fiber bundle. Thin-cladding fibers with highly accurate diameter were realized by chemical etching technique and were closely packed together in a ceramic ferrule to correspond with the MCF’s core layout. In this paper, we put the fan-out and MCF into SC connector housings, and confirmed that coupling loss was lower than 0.5dB and crosstalk was lower than -50dB at an environmental temperature within a range of -40~85deg C. We also confirmed higher than 50dB return loss across all the cores. This result means that stable physical-contact between the fan-out and MCF was kept in that temperature range.
