Official product information provided by LHY Audio
The following product descriptions, specifications and images are provided by the manufacturer.
LHY Audio FMC is an audiophile fiber media converter that changes Gigabit RJ45 Ethernet to an SFP optical link, or converts fiber back to copper. Its OCXO reclocking, isolated RJ45 port and low-noise linear power architecture support a galvanically isolated network path to a streamer.
Why it stands out
True external fiber link
The SFP interface breaks the copper electrical path.
Bidirectional media conversion
It can operate at either end of a matched fiber segment.
OCXO-based network clocking
An SC-Cut OCXO and PLL reclock Ethernet data.
Purpose-built low-noise power
Talema transformer, EMI filtering and linear regulation support the circuitry.
Best for
- Building an optical bridge to a streamer
- Separating router noise from the audio rack
- Pairing two converters across fiber
- Systems using compatible Gigabit SFP modules
Not ideal for
- Users wanting RJ45-in/RJ45-out in one box
- 2.5GbE or 10GbE endpoints
- Users without compatible SFP modules and fiber
- Systems needing multiple switched ports
EMiUZEK Buying Notes
- A complete bridge usually needs compatible conversion at both ends.
- SFP modules and fiber type must match.
- FMC is not a router or multi-port switch.
Frequently asked questions
Can one FMC create a complete fiber bridge?
Only if the other endpoint has compatible SFP; otherwise use a second converter.
Which module should I buy?
Matching Gigabit SFP modules and correct fiber type.
Can conversion run both ways?
Yes.
What speed does it support?
Gigabit Ethernet.
Does it provide Wi-Fi?
No.
What do LEDs show?
SFP link and network activity.
