FM481 4 Channel sFPDP Fiber Optical PMC/XMC


The FM481 is a high performance PMC/XMC module dedicated to high bandwidth communication. In addition to 4x 2.5Gbps optical transceivers for Fiber Channel and Gigabit Ethernet, the FM481 offers fast on-board memory resources and one Virtex-4 FX20/60 FPGA. The FM481 is based on the success of the FM482.
