2. The Fiber Modem comes equipped with a shielded RJ-45 Jack for
Ethernet connections (see Figure 1 on page 8).
Connect the Ethernet RJ-45 jack to the appropriate 802.3 compliant
network equipment via a standard network patch cable (not pro-
vided). The pinout diagrams in Figure 2 reflect the pinouts of the
Ethernet RJ-45 jack when switched to MDI and MDI-X settings.
Note Twisted-pair connections from the Ethernet RJ-45 Jack to the
network device should be 802.3 compliant (Category 5 STP or
UTP recommended) and must not exceed 100 meters (328
feet). Do not use flat or satin cable.
