2.2 DESCRIPTION
There are three base models in the Patton Model 1170M Series of stan-
dards compliant Ethernet Fiber Modems (see Table 1) that convert and
extend the reach of copper Ethernet over multi-mode fiber.
• The Model 1170M converts 100Base-TX to 100Base-FX and extends
up to 1.24 miles (2.0 km).
Note The Model 1172M can be used to connect auto-sensing 10/100
and 100Base-TX/100Base-FX network devices only; it is not
capable of connecting to 10Base-T/10Base-FL network devices.
• The Model 1171M converts 10Base-T to 10Base-FL and extends up to
1.24 miles (2.0 km).
Note The Model 1171M can be used to connect auto-sensing 10/100
and 10Base-T/10Base-FL network devices only; it is not capable
of connecting to 100Base-TX/100Base-FX or SX network
devices.
• The Model 1172M auto-negotiates and converts 10Base-T/100Base-
TX to 10Base-FL/100Base-FX and extends up to 1.24 miles (2.0 km).
Note The Model 1172M can be used to connect auto-sensing 10/100,
10Base-T/10Base-FL, and 100Base-T/100Base-FX network
devices. The Model 1172M cannot connect a 10Base network
device on one side to a 100Base network device on the other.
If a 10Base network device is on one side of the Model 1172M,
there must be another 10Base or an auto-sensing 10/100 net-
work device on the other. If a 100Base network device is on one
side of the Model 1172M, there must be another 100Base or an
auto-sensing 10/100 network device on the other.
The Model 1172M is the ideal product for customers who currently have
10Base-T networks and/or equipment and are planning to upgrade to
100Base-TX in the future. The Model 1172 provides a migration path
