A.1.3 EPIM-100FMB
The EPIM-100FMB shown in Figure A-3 supports multimode fiber optic
cabling and has an SC style connector.
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.
