E1 Quad Loop Extender
Module (EQLX)
The Soneplex E1 Quad Loop Extender (EQLX)
module converts four multiplexed, E1 signals
into an optical E2 for delivery over two
singlemode optical fibres. The optical E2 is
converted back to four E1s at the customer
premises. It supports optional 1+1 protection
and provides extensive alarms and diagnostic
capabilities.
ADC’s Soneplex system is the lowest total
cost solution for carriers to grow their E1-
based business services. Focused on providing
flexible, end-to-end solutions, the Soneplex
system saves carriers money on E1-based
services over copper or fiber, using HDSL or
optical E2 technology in a single platform.
From operations, maintenance, provisioning
and high-speed backbone connections to
central office space and cabling, the Soneplex
system is designed to take costs out of today’s
E1 delivery approach, adding profit to your
bottom line.
Features:
• 1310 nm optical laser transports signal more
than 32 Km
• Optional line and path protection with the

end. Protected mode requires two EQLX modules at each end of the circuit and is selectable by software
for either line or path protection. The EQLX is ideal for low density E1-based fibre applications, such as
cellular and PCS transport and tenant services within business parks or malls.
