CV08041JST/R is an audio optical terminal that uses dedicated ASIC design and high-speed DSP technology to support lossless transmission of 8 channels of forward audio, 4 channels of telephone voice, and 1 channel of Ethernet signal. It avoids the disadvantages of traditional optical terminals such as analog frequency modulation, phase modulation, and amplitude modulation, and has the characteristics of high quality and long-distance transmission.
The CV08041JST/R is an optical audio and Ethernet transmission unit that provides 8 channels of forward audio, 4 telephone voice channels and 1 Ethernet link over single‑mode fiber. It uses a dedicated ASIC and high‑speed DSP to deliver loss‑less, uncompressed 24‑bit audio up to 20 kHz and supports standard RJ‑45 10/100 Base‑T Ethernet.
The manual includes an overview of technical specifications, detailed installation and panel descriptions, wiring diagrams, typical applications, and service warranty information. Safety warnings address high‑voltage power and laser eye protection. This manual is written in Chinese.
