Real Cable OTT 70 Evolution
Real Cable OTT 70 Evolution optical cable with PMMA conductor, triple protection and metal-reinforced moulded connectors, for digital audio links.
Description
The Real Cable OTT 70 Evolution is a fibre optic cable designed to connect two audio devices via an optical digital link, such as a player, a box or a turntable to an amplifier or a DAC fitted with a Toslink input.
This cable relies on a PMMA (PolyMethylMethaAcrylate) fibre optic conductor, a technology commonly used for consumer optical audio links. It benefits from triple protection designed to preserve the integrity of the light signal and limit the risk of cable degradation over time. The connectors are moulded and metal-reinforced, a choice intended to improve the mechanical resilience of the connectors, particularly during repeated plugging and unplugging.
This type of cable is aimed at users wishing to establish or replace an optical digital link between two hifi or home cinema devices, in a configuration where this type of connector is already present on the equipment to be connected.

What to check before buying used
The sheath and moulded connectors deserve close inspection: bending too tightly or storing the cable coiled too tightly can weaken the PMMA fibre and cause micro-fractures invisible to the naked eye. Check that the connectors show no play or cracks around the metal reinforcement, a weak point in the event of knocks or repeated unplugging. A signal that cuts out intermittently or an optical end visibly dull or scratched often points to degradation of the conductor rather than a simple connection fault.
