SWITCHES
The OM101-AUI is available with ST or SC connectors; and
for singlemode or multi-mode fiber.
The OM101-AUI has a set of switches located on the end
panel. The switch functions are as follows:
APPLICATIONS
SQE/DSQE: The DSQE position disables the Signal
Connection of legacy 10 Mbps devices to 100 Mbps Quality Error signal (heart beat) on the AUI
