Holocom and Fiber SenSys Announce Successful Testing of New Alarm Processor Unit for SIPRNet

SAN DIEGO --  Holocom, the leader in protective distribution systems (PDS) for SIPRNet and other classified computer networks, and Fiber SenSys, the leader in fiber-optic sensor technology, announced that the U.S Navy and Army successfully evaluated the new SL508 and HC508 Alarm Processor Units (APUs) at Holocom headquarters in San Diego. The test was performed by members of the U.S. Navy/SPAWAR and US Army CTTA offices.  Holocom and Fiber SenSys made the announcement at the AFCEA WEST Conference in San Diego.

The Fiber SenSys SL508 and Fiber SenSys/Holocom co-branded HC508 provide an additional layer of protection to hardened carrier protective distribution systems for SIPRNet and other high-security government networks. The 508 was tested with four cable carriers comprising Holocom 2” x 2” two-piece Secure Raceway, Holocom solid tube Secure Mini Dukt™, one-inch steel EMT, and flexible interlocking armored fiber-optic cable.

The 1U 508 is capable of protecting eight zones of fiber optic or copper cable infrastructure. Each zone consists of single-strand sensing cable design, eliminating the need for loop-back cable in the cable carrier.  The system also includes enhanced tuning and calibration software for the elimination of nuisance alarms. 

Individuals requiring approvability for specific PDS projects should contact the appropriate service CTTA office.
