The FOM-5600 provides complete electrical isolation for 4-wire S/T-Interface ISDN communications. The unit has four channels that are independent of each other with two switches each that allow users to select between different ISDN modes and interfaces.
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. The potential problem of creating ground loops or ground offsets is also eliminated because signal ground is not carried over the fiber. The unit enhances privacy of communications because fiber can not be tapped without being detected and does not radiate any emissions. In addition, the FOM-5600 offers much longer transmission distances than traditional Cat5 cabling. Each channel can be retimed to allow longer S/T runs. A typical link consists of two FOM-5600, one at each end of the network with a duplex fiber optic cable between them.
