The VIT-42/TX and VIT-42/RX are unique, hardware based, single-direction “Transmit Only” and “Receive Only” full featured Fast Ethernet transparent converters providing 3R (Retiming, Reshaping and Regeneration) conversion between 100Base-TX copper media and 100Base-FX fiber media in compliance with IEEE802.3u standards. Data transfer in the opposite directions is completely blocked by both the TX and RX hardware circuitry respectively.

Designed and formally approved for Critical Infrastructure Protection (CIP) connectivity the VIT-42/TX provides fully secured copper to fiber single-direction data transfer over single/dual fiber connection to a standard 100Base-FX link partner, whereas the VIT-42/RX provides fully secured fiber to copper single-direction data transfer over dual fiber connection to a standard 100Base-FX link partner. Protection of the two sides of the link is achieved using a pair of VIT-42/TX and VIT-42/RX connected back to back over single fiber in the range of (0-100Km).

The separation between the pure HW network diodes and the unidirectional VectorIT SW application, installed on the networks endpoint servers, assures unbreakable single-direction solution for protecting networks against intrusion and leakage respectively.

VectorIT software application facilitates unidirectional transfer of certain TCP-based protocols as well as raw files over standard Ethernet interfaces with utilization of up-to full wire speed. Currently supported protocols are FTP, SMTP TCP and raw files. The software is dedicated to and employs only unidirectional data flow over single or bidirectional link, but has otherwise no relation to data security services.
