LHY FMC Fiber Media Converter

LHY Audio’s FMC (Fiber Media Converter) enhances digital audio performance by seamlessly converting RJ45 LAN signals (from routers or streamers) into fiber optic signals transmitted via optical fiber cables, or vice versa. Crafted for audiophiles with exacting standards, it delivers ultra-clean data transfer with minimal jitter, elevating your digital audio with exceptional clarity and precision. Perfectly suited for premium audio systems, it provides stable and noise-free media conversion for a refined listening experience.

LHY Audio's FMC (Fiber Media Converter) was designed to improve the sound quality in digital audio systems. Its main job is to convert a RJ-45 lan signal (from a router or streamer) into a fiber optics signal sent over an optical fiber cable, or convert it back to an electrical signal at the other end. 

Designed for discerning audiophiles, it ensures low jitter and ultra-clean data transfer, enhancing your digital audio experience with superior clarity and detail.

Ideal for high-end audio setups requiring reliable and noise-free media conversion.

Features

• Equipped with a digital isolation transformer
• Provides one RJ45 (ISO) port and one SFP port
• Utilizes an imported high-precision SC-cut OCXO temperature-controlled crystal oscillator with low phase noise PLL circuitry
• Features three independent ultra-low noise linear DC regulators using LT3042 + PNP configuration, achieving microvolt-level noise performance
• Integrated CNC-machined aluminum alloy chassis with compartmentalized internal layout to isolate different functional circuits, reducing interference and me
• Noise Isolation: The optical fiber cable blocks electrical noise from sources like power supplies and Wi-Fi routers. This prevents noise from traveling into your sensitive audio equipment.
  
• Cleaner Signal: By eliminating this noise, the FMC provides a much cleaner and more stable digital audio signal to your DAC (Digital-to-Analog Converter).
  
• Better Sound: The result is often an audible improvement, such as a blacker background, less harshness, and more detail in your music.
