Series of our products

• The telecom industry has been searching for the
  best way to deliver higher broadband speeds and a
  more stable service. Chengdu Widearea ADSL2 loop
  extenders solve this problem by boosting the
  ADSL2 signal so that it can reach further and be
  operated more reliably.
• ADSL loop extender is an active element,
  installed in the outside loop plant, that
  amplifies and equalizes the signal.
• Our Series A ADSL2 loop extenders work
  exceptionally well for reaching distant
  customers with ADSL2 service.
• The Series B IPTV Boosters are intended for
  boosting speed at closer distances.
• The Series L line powered loop extender which
  can be powered using power from the service pair.

• L Series Line Powered ADSL Loop Extender
• Our secret to success in using line power is
  to add additional power to the service pair. A
  telephone switch is not designed to be a general
  purpose power supply and its use as such creates
  some concerns for the service and the switch.
  When the telephone goes off hook, the voltage
  from the switch plummets from -48v to as low as
  -7v. This does not allow for a reliable ADSL
  extender or a reliable telephone service when
  both are competing for this limited power. We
  utilize a power supply in the central office to
  boost the signaling voltage well above 48v, so
  the loop extender can use the excess power yet
  pass the normal 48v to the telephone. By boosting
  the line power, you can significantly extend the
  reach of your ADSL services and improve the reach
  of your telephone service too!

Application Sample A Rural Independent Telco

• Distance from CO to CPE is 28,000 feet on 24 AWG
• ADSL service cant reach to the subscribers
  house because of too long distance
• With a loop extender between the two sites
  (14,000 feet), ADSL service is available.
