The Patton Model FOI-5601-L22 provides electrical complete electrical isolation and distance extension of 4-wire S/T interface ISDN communications. It is ideally suited for the extension of ISDN BRI, ISDN T interface, ISDN S bus interface, and PBX or SATCOM links. Traditional S/T cabling is limited to a maximum distance of 2,953 feet (900 m), 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).
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.
