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
