🔊 A Trusted Choice in the Audiophile Community

This single-mode LC/UPC to LC/UPC fiber patch cable by SpeedyFiberTX, featuring Corning® SMF-28® Ultra fiber, has become a popular upgrade option across audio forums in recent years.

Whether for two-channel streaming setups, digital streaming DACs, or high-end audio network switches, this cable integrates seamlessly.

Tested by audiophiles from Taiwan and around the world, it consistently delivers low noise, high signal clarity, and stable soundstage, even without special tuning or wrapping. It's often regarded as the best price-performance option among entry-level single-mode optical cables.

Need a longer run, or routing through walls/conduit?

This kit ships with a 1m cable for typical rack-to-rack or desktop setups. If your installation needs a different length, or you're routing fiber through walls, flooring, or conduit (e.g. during a renovation), pair these SFP modules with our Armored Single-mode Fiber Cable instead — same Corning G.657.A2 bend-insensitive fiber and 0.1dB ultra low loss performance, in a 3.0mm steel-tube armored, LSZH-jacketed build made for in-wall and outdoor duct routing.

🇺🇸 Buying from the US?

This fiber cable is also available bundled with our transceiver on Amazon — check out the bundle listing to save versus buying separately.

Recommended Pairing

For best results, pair with the SpeedyFiberTX Audio-Optimized SFP Module (SFP1G-LX-31-AF). This combo has been field-tested in Hi-Fi setups to provide optimal signal integrity from NAS to DAC through audio-grade switches.
