SPI Flash Connector (JSPI)

This is a point-to-point interface standard that allows network equipment designers to
develop an array of next-generation multi-service switches and routers for supporting
multi-service traffic with aggregate bandwidths of up to OC-192 (10 Gb/s). Thus, this
standard facilitates dramatic increases in system performance.
