NOT an analog to digital converter cable
This OPTICAL cable will NOT plug into your headphone jack and convert analog audio signals into digital audio with optical laser light. The center core is a plastic fiber optic cable with connectors on both ends with a jacket to protect it. It is specifically used to transmit digital (optical) audio. If you need an OPTICAL cable to go from mini-TOSLINK to standard TOSLINK, this cable will do the job.

Premium Fiber Core and Metal Connectors
Constructed from high quality low-loss, low-jitter, maximum signal transfer, precision polished fiber core to eliminates RF, EM, and ground loop interference. Coupled with heavy metal connectors to dampen vibration.

24k Gold-plated Ferrules with Strain-Relief PVC Jacket
24k gold-plated ferrules that resist corrosion, reduce tarnish, and provide maximum protection for the fiber tip. Quality PVC jacket contributes to the OD5.0mm strain-relief construction that not only provides flexibility, but also protects the cable from kinks.

Notes
