    The issue

    Each of the twisted pairs that make up the signal conductors running inside the ethernet cables is aluminium mylar foil shielded all along. However, a small portion of the aluminium mylar foil must be removed to untwist the pairs, crimp the contacts, insert them in the corresponding modules and place the contact modules inside the core shell. Along that very short stretch of cable with the mylar foil removed, shield continuity is interrupted. That’s exactly where the issue would arise….

    The core shell

    The core shell

    The shell at the heart of the Syntax® SGH series is indeed the core of the system. Not only it is a precision machined element housing the modules where the contacts are withheld; even more important than that is its function as an active component of the connector's shielding system.

    The shield drain

    After a small portion of the mylar foil has been removed (as described at # 1), the ethernet pairs are no longer fully shielded. For shield continuity, the drain wire of each ethernet pair is crimped onto a specific shield drain contact (a male pin) connected to a shield propagator (a female socket) inserted in the core element. For each ethernet line, there is a shield drain contact and a corresponding shield propagator.

    Full shield propagation

    The Syntax® SGH connector’s outer capsule has a conductive galvanic surface. Thanks to the combined action of the shield propagating contacts and the conductive treatment on the surface of the capsule, full shield propagation is obtained from cable to cable through the mated SGH connectors.  It’s as if your cables had never been interrupted! 

    Thanks to its conductive galvanic surface, the capsule is a double-purpose element that, in combination with the Syntax Safe Tunnels, creates an interference-free area providing full Next/Fext protection.
