which block any emissions XFP optical transceiver

typically used in conjunction with an XFP cage, flange and  gasket assembly, along with a heat sink and attachment clip, to connect an optical LC duplex or electrical XFP transceiver module to the host board. The right-angle interconnect is  an panel with compliant pins for pressing onto the host PCB. The cage assembly features four gaskets, which block any emissions emanating from the transceiver when installed. The front flange provides a flat surface to contact the  gasket (attached to the perimeter of the bezel cutout) and stabilizes the cage assembly during insertion and extraction of the transceiver.
Brocade10 Gbps Long Reach Multimode XFP optical transceiver, part of the Brocade family of optical transceivers, is optimized to fully leverage
Brocade 10 Gigabit Ethernet (GbE) switches and routers. Together, these
optical transceivers provide state-of-theart performance, helping IT organizations achieve new levels of infrastructure consolidation while expanding the capabilities of teir applications and services.
