Introduction

AROW

is a 1U rack mountable high availability, IPv4 based

Gigabit Ethernet uni-directional network access device (Data
Diode). TCP, UDP and Mulitcast protocols are supported
natively.

Internal simplex optical links between the unsafe nework (dirty)
and the secure and restricted network (clean) ensure a reliable
data link in one direction and guarantees no reverse data path.
AROW may be supplied in any of 3 basic configuations

– single

channel, dual channel or high-availability redundant single-
channel.
Plug-in data interfacing allows connections to RJ-45 Copper
Gigabit Ethernet and/or Optical Fibre Gigabit Ethernet.
