The FOI-5402 and TD-5402 provide complete electrical isolation for E1 communications. 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. In addition, fiber optic cable offers much longer transmission distances than copper wiring. Traditional E1 cabling is limited to a maximum distance of 4800ft (1.46km), but multimode optics on the unit can extend the distance to 2km, while singlemode optics can further extend the distance to 20km. A typical link consists of two FOI-5402, one at each end of the network, with a duplex fiber optic cable between them. What’s the difference between the FOI and the TD versions? Functionally, the FOI-5402 and TD-5402 are identical. The only differences are the packaging and power supply. The FOI-5402 is part of the FOI line of products designed for ruggedized military applications while the TD-5402 is housed in the commercial ‘Throw Down’ packaging.
