Quad Loop Extender Module (QLX)
The QLX module is a fiber loop converter that provides cost-effective, reliable transmission of 4 DS1
signals, utilizing 6 Mbps optical DS2 transport, up to 20 miles. It converts four multiplexed DS1 signals
into an optical DS2 for delivery over single-mode optical fibers. The optical DS2 is converted back to four
DS1s at the customer premises. The QLX utilizes two fibers, with either an FC or SC type connector, and
can operate in protected or non-protected modes. Non-protected mode requires one QLX module per
four DS1s installed in the Soneplex Loop Extender Chassis at the central office, and one QLX module at
the remote end. Protected mode requires two QLX modules at each end of the circuit and is selectable
by software for either line or path protection. Integrated network management enables extensive alarms
and diagnostic capabilities.
At the central office, the QLX module can be used in an ADC Soneplex Loop Extender chassis or in an
industry-standard 3192 repeater shelf with an optional adapter board. At the customer premises, the
QLX module fits into either a two or four position remote chassis available from ADC.
Features
• 1310 nm optical laser transports signal up to 20 miles
• Optional line and path protection with the CPM module
• Remote loopback of individual DS1 circuits
• Software selectable AMI and B8ZS line codes
• Central office and remote alarm capability
• Fits into ADC Soneplex Loop Extender chassis and industry-standard 3192 repeater shelf with an
adapter board
The Soneplex Quad Loop Extender (QLX)
module is part of ADC’s cost-effective
solution for T1-based service delivery. The
Soneplex platform supports DS1 network
interfaces on either copper or fiber using
HDSL, HDSL2, HDSL4, traditional T1 repeater

or optical DS2 technology in a single
platform. Integrated network management
lets carriers save on overall operations costs
through the entire system lifecycle.
