Network & Communication

Unidirectional communication is often used to safeguard information in secure environments such as government agencies and military networks. A Unidirectional device, sometimes referred to as a unidirectional security gateway or a data diode, provides a connection between two or more networks with different security classifications and helps to protect assets by ensuring information is directed only to, or from, the appropriate network as designated by the directional device.

Unidirectional media converters combine this one-way communications with the benefits of a copper to fiber media converter. Media converters are a cost-effective, plug-and-play device that allows fiber optic cabling to be connected to copper-based networking equipment. The deployment of fiber adds a layer of security to networks as it is difficult to tap into fiber and go undetected. If threats are attacking a network, the fiber links go down and network administrators are made aware of the problem, providing them the opportunity to address a potential breach of security.

Adding unidirectional technology to a media converter creates a physically secure one-way communication channel over fiber between a secure network and an unsecure network. These devices can be used to allow data from a classified, high-security area to be transmitted to a low-security area, while preventing unsecure data from re-entering the classified network. An alternate application allows a secure network to be updated with data from an external source while ensuring its critical data is unable to leave the classified area.

The Fast Ethernet Media Converter connects 100Base-TX Fast Ethernet twisted-pair copper network devices to network devices on a 100Base-FX Fast. Bridging media converter will provide conversion and integration solutions for half and full-duplex environments.

The SFMFF stand-alone, when used individually or in pairs, functions as a mode converter that extends Gigabit Ethernet or Fiber Channel signals over single mode fiber up to 125 kilometers. The SFMFF also converts 1000Base-SX ports on a Gigabit Ethernet switch to 1000Base-LX on a port-by-port basis.
