Tested on a Philips 3D screen optical output with an optical cable (HQ HQSS4623 / 2.5 Cable toslink 2.5m from the same seller Indpc) to a Sony home cinema. Very good quality, no signal loss, hinged overcap (turns on itself to guide the cable from the best possible way and combine it with other cables from the TV to cleaner) For that price in Indpc, do not deprive yourself of your cables tidy cleverly behind your tv!
