A splitter for sending one optical digital audio source to three destinations at once. It carries the signal only, so every device on the far end still needs its own optical input.

Overview
Not an amplifier and not a converter, LiNKFOR's optical splitter takes a single Toslink digital audio feed and copies it to three optical outputs. A Blu-ray player, game console or set-top box connects on the input side, while soundbars, headphones or amplifiers with optical inputs take the outputs. The unit runs from mains power and shows its status with a power indicator light.
One optical source feeding several listening points is the whole point here, and the built-in fiber cables remove a layer of extra wiring from the setup. Signal loss along the run stays low enough to reach distant rooms. What it will not do is change the audio format or drive speakers on its own, so each output still lands at a device that can decode the stream.
Who it's for
Rooms where a single game console or disc player has to reach a soundbar, a headphone dock and a receiver, all with optical ports, are what this suits. Buyers expecting it to convert between audio formats or to power speakers directly should look elsewhere.
Pros and cons
- Splits one optical source to three outputs
- Handles LPCM, DTS and Dolby-AC3
- Built-in fiber cables simplify wiring
- Low signal loss over long runs
- Optical input only, no coaxial option
- No format conversion between devices
- Each output needs its own optical device
- Power outlet required for operation
Performance notes
Signal integrity depends on the optical path: the unit copies the incoming digital stream to each output through its built-in fiber runs, and loss stays under the stated per-meter figure, which is what allows the long output distance. Anything the source sends arrives unchanged, so the receiving soundbar or amplifier does the decoding. Mains power holds the splitter active, and the indicator light confirms it is running.

Frequently asked questions
What comes in the box with the LiNKFOR 1x3 splitter?
The splitter itself with its built-in optical fiber cables, plus one optical audio cable. The listing does not name a power adapter or remote, so plan around what is shown in the included components.
Does the LiNKFOR splitter change the audio format?
No. It passes LPCM 2.0, DTS and Dolby-AC3 streams through to the outputs as they arrive, so each connected soundbar, headphone or amplifier must be able to decode the format the source sends.
Can I connect a coaxial digital source to this splitter?
No. The input is optical Toslink only, so a coaxial digital output needs a separate converter before it reaches this unit.
How far can the optical signal travel from the outputs?
The listing rates output distance at up to 40 m, helped by low optical loss of under 0.2 dB/m along the fiber.
Does the LiNKFOR splitter need power to work?
Yes. It runs on mains supply between 100 and 240 volts AC, and the power indicator light shows when it is operating.
