enough, arching between cable segments and smoked network interface components
are possible. Fiber optic cable is immune to these phenomena.
Fiber is recommended for distances greater than 100 meters or as a solution to
ground potential issues. A number of cost effective media converters conforming to
this standard are available. Many use fiber connectors that are easy to terminate.
The recommend media converter from Transition Networks (as well as other suppliers)
uses ST type fiber connectors that are easier to terminate than other types of fiber
connectors. In addition, prefabricated fiber cables of various lengths pre-terminated
with ST connectors are available.
Recommended Fiber Based Media Converters
One of the most efficient ways of extending a 100Mbps cable segment beyond the
90 meter limit is with a pair of media converters. These devices allow you to insert
a fiber cable between two copper cable segments to extend the total distance
between two Ethernet devices.
In a structured cabling system, individual cable runs are limited to 90 meters (100
meters minus 10 meters for patch cables at each end), or 295ft. However, running
an Ethernet cable beyond this distance is often a requirement for large sites. In
addition, the use of a media converter can also be used to isolate clusters of
MICROS equipment if a site is experiencing AC ground potential issues.
Media converters are available that can increase the distance between any two
Ethernet devices up to 2000 meters, (6,600ft) using multi-mode fiber, or up to
20000 meters (66,000ft) using single mode fiber without a repeater.
Oracle MICROS recommends Transition Networks copper to fiber media
converters. These devices can extend a cable segment up to 2000 meters, more
than adequate for most situations. Other features include power, data, and link
status indicators.
