fiberplex FOI-5401-RL5B Isolator for T1 DS-1 or ISDN PRI Interface

The FOI-5401and TD-5401 provide complete electrical isolation for T1 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 T1 cabling is limited to a maximum distance of 6200ft (1.89km), 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-5401, one at each end of the network, with a duplex fiber optic cable between them.
