SONEPLEX QUAD LOOP EXTENDER MODULE
The Soneplex Quad Loop Extender (QLX) module
converts four multiplexed, DS1 signals into an
optical DS2 for delivery over singlemode optical
fibers. The optical DS2 is converted back to four
DS1s at the customer premises. It supports op-
tional 1+1 protection and provides extensive alarms
and diagnostic capabilities.
