Fiber Transmission Products

N3784 series provides the ability to transmit and receive up to 4 channels, 4 ports, 10/100Mbps auto sensing Ethernet signal over one fiber.

Modular in design, N3784 series can be rack-mounted or used as a stand-alone module. Rack mounting requires the N3910 series subrack. Stand-alone module is accomplished with the N3910-1S and can be placed on a desktop or mounted to a wall.
