    Protecting what is most valuable

    Protecting what is most valuable

    The main purpose of an effective shielding solution is to protect all signals from interferences. External noise is a common issue on connectors and must be addressed properly. In a hybrid, modular, feature-rich connector as Syntax® SGH is, the main challenge is prevent any cross interference between signal conductors running close to each other. That's why we came up with an innovative design that not only solves problems related to interferences, it also allows quick wiring operations.

    Every core element has several openings, one for each pair of signal conductors, leading to tunnels that cross the core through all its length. The Syntax Safe Tunnels play a decisive role in shielding our Syntax® SGH connectors from all internal and external interferences.

    The issue

    Each of the twisted pairs that make up the signal conductors running inside the ethernet cables is mylar/aluminium foil shielded all along. However, a small portion of the mylar/aluminium  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 pairs no longer twisted and their shield removed, it would be as if the wires were in the open, totally exposed to interferences. That’s exactly where the issue would arise…

    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 with held; even more important than that is its function as an active component of the connector's shielding system.

    The “no longer twisted” ethernet pairs, now crimped and locked in the contact modules, are channeled along the tunnels of the core element that serves as their housing.

    When modules and cables are in place, the thick inner walls of the Syntax Safe Tunnels provide a barrier against reciprocal interferences (crosstalk) between the pairs placed in each tunnel.

    The sensible areas shown at point 1, however, would still be partially exposed to reciprocal interferences, as the gaps in the slots allowing easy access for the wires inside the tunnels would impede complete shielding. A specifically designed capsule seals the slots on the outer side of the tunnels, creating an area totally free from crosstalk, reduced Next/Fext level.

    Thanks to its conductive galvanic surface, the capsule is a double-purpose element also providing complete shield propagation from cable to cable through the mated SGH connectors.

    When the capsule is in place and mated with a second connector, the complete shielding structure extends from the starting cable through the connector and onto the next connector to the destination cable.
