Government and military networks often utilize the concept of unclassified (black) networks
vs classified (red) networks to manage levels of information security. Since a complete
“air-gap” around a highly sensitive network is not practical, every data connection is
evaluated as a security risk. To synchronize a master source of time on a red network, Spectracom offers a fiber optical IRIG time code link between a SecureSync master-slave pair to offer high accuracy timing to a classified network while satisfying the requirements of SIPRNET, NIPRNET and other ultra-secure network systems.
