Figures and illustrations are for identification only and i are not drawn to scale. 1. INTRODUCTION This specification covers the requirements for application of the zQSFP+/QSFP28 behind/Thru bezel cage assembly, heat sink, EMI/dust cover, and light pipe that are used in conjunction with 38-position, 0.8 mm pitch, right-angle surface mount, zQSFP+/QSFP28 connectors used in the communications industry. The cage assembly serves as a housing for the connector and mating transceiver. The cage assembly is a frame with compliant pins for mounting onto the host printed circuit (pc) board. The cage assembly features front perimeter electromagnetic interference (EMI) springs. These springs block any EMI emissions emanating from the transceiver when installed. The cage assembly is designed to be bezel mounted. Behind bezel type, the front flange provides a flat surface to contact the EMI gasket attached to the perimeter of the bezel cutout. Thru bezel type, the front perimeter EMI spring/conductive elastomeric gasket contact the perimeter of the bezel cutout directly. The cage assembly transceiver locking latches hold the transceiver in place, and the hard stop controls the insertion depth of the transceiver. The optional heat sink are located on the top of the cage assembly and are used to transmit heat from inside of cage assembly to outside. The optional light pipes are located outside of the cage assembly and are used to transmit light from up to LEDs on the pc board to a panel. The EMI/dust cover is used to confine EMI emissions and prevent contaminants from entering the chassis when the transceiver is not installed. This specification covers the requirements for the zQSFP+/QSFP28 Cage Assemblies with EMI Spring Fingers onto printed circuit (pc) boards and bezel. The cage assemblies are available in single port 1x1 or ganged 1x2, 1x3, 1x4, 1x5, and 1x6 configurations. All configurations are available with, or without, optional heat sinks in different heights (PCI, SAN, NETWORKING, and CUSTOMIZED). All configurations are available with, or without, optional light pipes with three different display options (single, dual, and quad).
