Fiber optic audio cables, as the name implies, use fiber optics to transmit sound. Basically, digital sound is converted into light waves, which are then transmitted along the fiber optic cable. These are increasingly becoming the popular choice for transmitting sound in high definition home audio systems.
Fiber optic audio cables not only provide an improvement in audio quality over traditional coaxial cables; They also prevent any electromagnetic interference from affecting sound quality. These cables also allow you to transmit sound over long distances without any appreciable loss of audio cables. Fiber optic audio cables are a hassle-free method of connecting your audio system to a preamplifier or receiver. Here are some tips on how to troubleshoot common fiber optic audio cable problems.
Step 1 – Check compatible connectors
Fiber optic audio cables come with a variety of connectors, the most popular being square-shaped. You need to make sure that the cable you have purchased has connectors that match the optical audio jacks on your audio equipment. Otherwise, you will have to buy another cable with the correct connectors because mismatched connectors will never fit properly.
Step 2 – Remove the caps
Fiber optic audio cables come with caps on the connectors to protect them. These covers must be removed before connecting cables to your audio equipment. Even the optical audio output and input jacks on your audio equipment may have plastic or rubber caps that must be removed before installing cables. Although this may seem elementary, the main failure to remove the plastic plugs is the main reason why optical audio cables do not work. If you don’t remove the cap and try to force the cable, you can also end up damaging both the cable and your audio system.
Step 3: look for a sign
Some audio equipment may have a setting or switch that must be turned on to enable optical audio output. If you don’t turn it on, you won’t be able to hear any sound. A good way to check if your audio source is transmitting optical audio signals is to connect your cable to the optical audio source and turn on your equipment. Check the other end of the cable for visible light. Otherwise, no optical audio signal is transmitted and you should check your equipment settings.
Step 4 – Check the curves
Light travels in a straight line, so fiber optic audio cables do not perform very well if they are twisted or bent. Try straightening the cable and see if the sound resets. Also, keep in mind that optical audio cables are more delicate than coaxial cables, so if they were bent too much or stepped on, they could have been damaged. Again, connect one end of the cable to your audio source, turn on your audio equipment, and check the other end of the cable to see if light is transmitting.
