Works 1A snaps good and absolutely a densely.

With this fiber optic cable do I connect my LED TV and the PS3 via the optical digital output to the home theater system.
The connection is very easy, both protective caps from the Toslink cable plugs and insert the plugs in the optical outputs / inputs. The plugs are handy with groove and snap a noticeably with an audible click. Boldly push, for me it is the "Knack" only with some force. They close tightly, this is the case of optical connections so one of the main quality criteria.
Never leave lying around the plug, always plug the protective caps. Is coming in as soon as microscopic dust the fiber optic cable is defective (sound skips, distortion, etc.). Likewise, it is defective when it is bent excessively. In both cases, the light beam is not exactly routed but partially deflected from the target, or simply swallowed. So then no longer arrive at the recipient information.
Never bend the fiber optic cable by force into a desired shape or make / squeeze a device on the cable!

A "screening" of the cable as with metal cables (eg RCA or HDMI) is not required for optical cables. Important high-quality plastic coating is (here: black) the fiberglass to protect against scratch damage. So then the whole thing looks just like a "cable" from.
The tone has been designed for much better than RCA metal ladder. It eliminates any susceptibility to noise such as hum, crackle, noise, etc..
Of course in the configuration menu or setup the device's audio output / input must be set to Visually, some equipment may not automatically listen on the optical port.

Tip:
In case of problems with the sound an attempt of replacing the cable is first useful especially in optical fiber optic cables. The fiber optic cables go very quickly broken by invading dust or breaks. This is especially true "mobile" PS3 users who are constantly the equipment in the living room / children up / abbbauen.

Conclusion:
This cable of Hama (Hama Optical digital cable 2x ODT Toslink 1.5m) is very high quality and works 1A. For the reasonable price suitable as "consumable" for children and their PS3.
May this review for many be helpful.
