4Gbps High-speed
Optical Communication Board


AGM-741 is a card type GiGA CHANNEL module. which enables communication in your equipment with 4.25Gbps hight-speed serial bus.
It allows easy implementable by connecting optical cable in AGM-741 to connecting equipment with memory-like interface.
Since communication protocol processing is performed on the hardware, no special processing is necessary.
