【Overview】 This is the "OPT-1000" optical digital cable from Ortofon, a long-established Danish audio brand. It is a genuine optical digital cable designed with a focus on materials and construction. 【Condition】 ・Fully functional, confirmed to be working ・Shows little signs of use and is in very clean condition overall ・No noticeable scratches or deterioration on the cable sheath or terminals ※Please check the photos for detailed condition 【Details】 The OPT-1000 uses pure quartz fiber as its core material. Unlike general resin-based fibers, the use of quartz material, which has excellent light transmission characteristics, is designed to transmit digital signals more stably. The cable section is constructed to withstand external physical stress, making it less susceptible to bending or handling. The terminals are also precisely molded, allowing for a stable connection with the optical terminals on the equipment side. I used it for about 10 years for optical digital connection between my PC and speakers, and there were no connection problems or transmission issues during that time. I am selling it because I can no longer secure a place to set up my speakers due to moving. This is a suitable cable for those looking for an optical digital cable that emphasizes materials and construction, or for those who want to choose a model that uses pure quartz fiber. Please consider this item with the understanding that it is a used product. If you have any questions, please ask in the comments. Thank you for viewing.
