The UGREEN AV122 is a two-meter Toslink optical audio cable designed to transmit high-quality digital sound between your devices. By utilizing the S/PDIF protocol, it supports Dolby 7.1 surround sound, making it a reliable choice for connecting televisions, game consoles, and Blu-ray players to soundbars or home theater receivers. To ensure a stable connection, the connectors are 24K gold-plated, which helps prevent oxidation and reduces signal loss over time. The cable is encased in a flexible PVC outer jacket with durable plastic housing, allowing you to easily route it through tight spaces behind your entertainment center. For added convenience, it comes with protective caps to keep the connectors clean and safe when not in use.
