A TOSLINK optical splitter takes one digital audio output from a TV, console or streaming box and feeds it to two or three devices, such as a soundbar and an amplifier. The designs differ: some are passive fiber parts, others are powered boxes with their own electronics.
The six splitters below range from simple 1×2 adapters to powered 1×3 units. Specs come from each listing page. We have not used these products ourselves, and format and distance claims are the makers’ own.

What to Look For
| Feature | Why it matters |
|---|---|
| Number of outputs | A 1×2 or 1×3 layout decides how many devices you can feed |
| Powered or passive | Powered units list longer runs; passive ones need no power cable |
| Audio formats | Optical carries stereo PCM, Dolby Digital and DTS 5.1, not 7.1 formats |
| Connector layout | Check whether outputs are sockets or a plug with a cable |

The 6 Best TOSLINK Optical Splitters
1. KabelDirekt TOSLINK Splitter 1 to 2
A one-plug, two-socket Y adapter that connects one optical output to two playback devices, for example a TV and a soundbar at the same time. The listing names TVs, amplifiers, soundbars, PCs and game consoles as compatible, and says it can also join two sources to one receiver. The connector gender field reads female-to-female while the bullets describe a plug, so check the photos.
Suits: a simple two-device split. Strengths: no power needed and a stated two-way use. Weaknesses: conflicting connector wording. Skip it if you need three outputs.

2. SOUNDFAM Optical Audio Splitter 1 in 2 Out
A 1×2 splitter with one male input and two female outputs, a braided jacket, metal connectors and an ABS body. The listing lists stereo, surround and 5.1 or 7.1 channel modes but also warns that the two outputs cannot work at the same time, which limits its use for feeding two devices at once.
Suits: switching one source between two receivers. Strengths: braided cable and metal ends. Weaknesses: outputs are not simultaneous per the listing. Skip it if you want both devices playing together.
3. avedio links Optical Audio Splitter 1 in 2 Out
A fiber splitter with one male input and two female outputs, listed for LPCM 2.0, Dolby Digital and DTS 5.1 and for use with Xbox, PS4, TV boxes and soundbars. The listing describes using a soundbar and a headset together with separate volume controls, and gives a 2 year warranty.
Suits: a soundbar plus a headset adapter. Strengths: a 2 year warranty. Weaknesses: only two outputs. Skip it if you need more than two devices.
4. LiNKFOR Digital Optical Audio 1×3 Splitter
A 1×3 aluminum alloy splitter with an optical cable included, measuring 6.3 x 3.94 x 0.91 inches and weighing 2.47 ounces. It supports PCM, LPCM 2.0, Dolby AC3 and DTS 5.1 at 32, 44.1, 48 and 96 kHz, and the listing says 7.1 formats cannot pass over optical. The maker lists over-voltage protection and runs up to 25 meters.
Suits: feeding three devices. Strengths: metal body and a cable in the box. Weaknesses: no 7.1 formats. Skip it if you want a smaller unit.
5. MAYWILLA 1 in 2 Out Splitter Cable
A one-meter braided splitter cable with one plug at the source end and two plugs at the other, so no socket adapter is needed. The listing says it feeds a receiver or soundbar and a second device with a TOSLINK port at the same time, and lists a PVC outer material. The brand field says Generic while the manufacturer field names another maker.
Suits: a TV with a free optical output. Strengths: a single cable with no extra adapter. Weaknesses: fixed 1 meter length and unclear brand. Skip it if you need sockets or a longer run.

6. cooidea 1 in 3 Out Optical Splitter
A compact Type-C powered 1×3 splitter measuring 54 x 35 x 18 mm, with an independent switch for each output. The maker lists support up to 192 kHz and 24 bit, plus LPCM 2.0, DTS and Dolby AC3 5.1 channels.
Suits: turning outputs on or off. Strengths: per-output switches and a small body. Weaknesses: needs Type-C power. Skip it if you have no spare USB port.
Setup Notes
- Remove the small dust caps from each optical port before plugging in.
- Do not bend optical cables sharply.
- Set the source device to PCM or Dolby Digital output as the receivers allow.
- Connect power first on the powered units.
Mistakes to Avoid
- Expecting 7.1 or lossless formats over optical.
- Assuming both outputs of a 1×2 work together without checking the listing.
- Forgetting that powered models need a USB source.
- Buying a splitter when an HDMI audio extractor is the better fit.
TOSLINK Splitters FAQ
Do these include an optical cable?
The LiNKFOR lists an optical cable in the box. For the others, check the listing contents.
Which ones need power?
The cooidea uses Type-C and the LiNKFOR is a powered unit. The KabelDirekt, SOUNDFAM, avedio links and MAYWILLA are described as passive.
The Short Version
For a plain two-way split, the KabelDirekt or avedio links. For three outputs with a cable, the LiNKFOR. For a one-cable split, the MAYWILLA. For switches, the cooidea. Read the SOUNDFAM note on its outputs first.
