The built-in optical drive has been abandoned by laptops and desktop PC for many years, and also no exception for Apple products.

Unlike fiber optical audio splitter, Toslink optical switcher allow you to access multiple source devices (such as you have one TV, one Blu-ray player, one Apple TV), to a playbar or other audio receiver with fiber optic port, and control it through buttons or IR remote control.

If you just require more HDMI ports on TV, 3 in 1 out or 5 in 1 out HDMI switch should be enough, but if you have two display devices and want to be able to switch between multiple HDMI source devices on them, HDMI switch with 2 HDMI output ports is required, which is also referred to as HDMI matrix switch.

If you need more HDMI port on your TV, or diplay the same content on multiple TVs / monitors simultaneously, an HDMI switcher or HDMI splitter is enough. However, if you need to use multiple HDMI source devices and multiple high-definition display terminals at the same time, and want to be able to arbitrarily control the transmission of one or more HDMI signals to one or more display devices, the solution is HDMI matrix switch.
Some days ago, we introduced some HDMI audio extractor converters with different HDMI version (HDMI 1.3, 1.4 and 2.0). In addition to the HDMI version, the function of splitting the audio is the same.
