Toslink DLR1120

The Toslink DLR1120 is a fiber optic receiver module, crucial for digital audio transmission. It works in conjunction with the Toslink DLT1120 transmitter to establish an efficient digital audio transmission link.

Operating Principle and Signal Processing

The DLR1120 performs the critical task of converting optical signals into electrical signals. Upon receiving the optical signal from the plastic optical fiber, its sophisticated optoelectronic conversion components quickly and accurately convert it into an electrical signal. This extremely precise conversion process preserves the original characteristics of the audio signal to the greatest extent possible, ensuring high-fidelity sound quality for subsequent audio processing and playback. Whether it's the subtle vibrato of a string instrument in music or the distant ambient sounds of a movie surround sound, both are faithfully reproduced, delivering an immersive audio experience.

Toslink DLT1120

The Toslink DLT1120 is a professional fiber optic transmitter module that complements the DLR1120 to achieve high-speed fiber optic transmission of digital audio.

Operating Principle and Signal Processing

The DLT1120's core task is to convert electrical signals into optical signals for long-distance, low-loss transmission via optical fiber. When it receives electrical signals from an audio source device (such as the electrical audio signal output from a computer sound card or a digital player), its internal light-emitting element accurately converts them into corresponding optical signal pulses based on the electrical signal's changing patterns. These optical signal pulses, when transmitted through plastic optical fiber, effectively reduce signal interference and attenuation. Compared to traditional audio cable transmission, this significantly improves audio signal transmission quality and distance, paving the way for high-quality long-distance audio transmission.
