Loopback Modes
This feature allows three distinct Loopbacks to be activated either through DIP Switches or iView2 Management.
Fiber | An analog Loopback at the copper port back to the fiber port. It |
Loopback | copies the received optical signal back to the optical line at the |
| copper port and continues to drive the copper port, but can be |
| corrupted by noise on the copper port. |
Internal | A local Loopback at the fiber port. It copies the received optical |
Fiber | signal back to the optical line at a digital point internal to the unit. |
Loopback | It continues to drive the copper port, and normal copper line |
| monitoring is maintained on the copper port, but the returning |
| data pattern is not affected. |
Copper | A remote Loopback to copper port at the fiber driver. It copies |
Loopback | the received copper signal back to the copper port and continues |
| to drive the fiber port. |
By default all Loopbacks are set to OFF for normal data operation.
The following illustrations show the path that a signal takes in each of the Loopback test modes.
