Figure A-3 EPIM-100FMB

The EPIM-100FMB acts as a non-filtering bridge. Its purpose is to extend the Broadcast Domain of a shared access 100BASE-T LAN, so that a full length of fiber optic cable can be used to reach the next domain or more typically to a switch port.

The maximum diameter of a 100BASE-T collision domain using UTP cable to the desktop and fiber cable in the next domain or switch port is only 263 meters (100 meters of UTP and 163 meters of fiber optics). There are circumstances where the maximum fiber optic cable length of 163 meters does not meet some requirements such as in the cabling of high rise buildings or campus environments. The EPIM-100FMB helps meet these requirements by extending the maximum fiber optic cable length that can be used from 163 meters to 400 meters.

Table A-2 provides the specifications for the EPIM-100FMB.
