GBIC fibre-optic shield

14 February 2001 Circuit & System Protection

Instrument Specialities has introduced the GBIC shield for reducing emissions from GBIC (GigaBit Interface Converter) fibre-optic transceivers. Fibre-optic transceivers can be a troublesome source of EMI because they emit high frequency signals and are located adjacent to large apertures in the enclosure. The GBIC fibre-optic shield assembly reduces the radiated emissions from the transceivers by conducting interference current away from the transceiver and onto the enclosure surface.

Simple assembly of the shield is accomplished by snapping the two shield halves onto an uninstalled guide rail assembly. The rail is then mounted onto the PCB in the normal fashion.

Spring finger design on both halves of the GBIC shield provide grounding for both sides of a transceiver module. In addition, the bottom half fingers can provide a low impedance connection to the circuit board ground plane.
