FiberPlex FOI-STS1 Fiber Optic Isolator/Converter/Modem - STS-1 to OC-1; mission critical packaging

Packed in rugged military style metal enclosure, the FOI-STS1 Series is a STS-1/OC-1 Fiber Extender and Isolator

The FOI-STS1 provides electrical isolation and extension of STS-1/OC-1 signals to SONET add/drop multiplexers, PDH equipment or WAN routers. Traditional STS-1 coax cabling is limited to a maximum distance of 1,100 feet (335 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.

FOI units can be mounted in several redundant powering chassis; rack and wall mount options including Tempest and NEMA alternatives.

A typical link consists of two FOI-STS1s, one at each end of the network, with a duplex fiber optic cable in between.
