3.2.3 Connecting Single-Mode
Fiber Optic
When using single-mode fiber cable, be sure to use single-mode fiber port
connectors. Single-mode fiber cable has a smaller diameter than multi-mode fiber cable
(9/125 microns for single-mode, 50/125 or 62.5/125 microns for multi-mode where xx/xx
are the diameters of the core and the core plus the cladding respectively). Single-mode
fiber allows full bandwidth at longer distances, and may be used to connect 10 Mb nodes
up to 10 Km apart, or 18Km with the 6K-SSC.
The same procedures as for multi-mode fiber, applies to single-mode fiber
connectors. Follow the steps listed in Section 3.2.2 above.
3.2.4 Connecting Twisted Pair (RJ-45, CAT3, CAT5, Unshielded or
Shielded)
The RJ-45 ports of the Magnum 6K16-Series can be connected to the following
two media types: 100BASE-TX and 10BASE-T. CAT 5 cables should be used when
making 100BASE-TX connections. When the ports are used as 10BASE-T ports, CAT 3
may be used. In either case, the maximum distance for unshielded twisted pair cabling is
100 meters (328 ft).
Media
IEEE Standard Connector
Twisted Pair (CAT 3, 4, 5) 10BASE-T RJ-45
Twisted Pair (CAT 5) 100BASE-TX RJ-45
NOTE : It is recommended that high quality CAT. 5 cables (which work for both 10 Mb
and 100Mb) be used whenever possible in order to provide flexibility in a
mixed-speed network, since dual-speed ports are auto-sensing for either 10 and
100Mb/s.
The following procedure describes how to connect a 10BASE-T or 100BASE-
TX twisted pair segment to the RJ-45 port. The procedure is the same for both
unshielded and shielded twisted pair cables.
1. Using standard twisted pair media, insert either end of the cable with an RJ-45
plug into the RJ-45 connector of the port. Note that, even though the connector is
shielded, either unshielded or shielded cables and wiring may be used.
2. Connect the other end of the cable to the corresponding device
3. Use the LINK LED to ensure proper connectivity by noting that the LED will be
illuminated when the unit is powered and proper connection is established
NOTE: for Power Substations
: In support of the IEEE 1613 Class 2 standard, GCI
advises that, for substation applications, the RJ-45 ports are intended for
connectivity to other communication equipment such as routers or
telecommunication multiplexers installed in close proximity (i.e., less than 2
meters or 6.5ft) to the 6K16(V). It is not recommended to use these ports in
substation applications to interface to field devices across distances which
could produce kigh (greater than 2500V ) levels of ground potential rise (GPR)
during line-to-ground fault conditions. The 6K16(V) passes the
1613specifications for zero packet loss with fiber ports & with RJ45 ports used
as indicated here.
