FiberPlex FOI-5401 Fiber Optic Isolator/Converter/Modem - T1 or ISDN PRI; mission critical packaging



Packed in rugged military style metal enclosure, the FOI-5401 provides isolation and extension of T1 signals. This unit is ideally suited for T1 trunk or backhaul, or for the extension of ISDN, PBX, and SATCOM links.
Overview
The FOI-5401 provides electrical isolation and extension of T1 signals. These units are ideally suited for T1 trunk or backhaul, or for the extension of ISDN, PBX, and SATCOM links. Traditional T1 cabling is limited to a maximum distance of 4,800 feet (1.46 km), but multimode optics on the unit can extend the distance to 1.2 miles (2 km), while singlemode optics can further extend the distance to 12.4 miles (20 km) or more.
 
The unit can be used in areas of high electrical noise or in and out of RF shielded enclosures. The fiber optic cable is not susceptible to interference caused by impulse noise, crosstalk, or EMI. Privacy of communications is also enhanced because the fiber optic cable does not radiate any emissions. FiberPlex recommends “R” units for high security applications because the units have added filtering and shielding for RFI suppression.
 
FOI version units can be mounted in several redundant powering chassis; rack and wall mount options including Tempest and NEMA alternatives.


Applications
A standard link would consist of two FOI-5401s, one at each end of a fiber cable connection. These units create a simple plug and play point to point fiber extension for T1 circuits which makes deployment of circuit extensions fast and easy. See the diagram below for a diagram of typical endpoints that can be supported by the FOI-5401.
