Cisco Catalyst PON Series ONT Overview

The Cisco Catalyst PON Series ONT is an optical modem device that is integrated with powerful interoperability
and high performance. (An ONT is also referred to as Optical Network Unit [ONU]. ONT is an ITU-T term,
while ONU is an IEEE term.) The Cisco Catalyst PON ONT is located at an end user's premises. The Cisco
Catalyst PON Series ONT connects to the PON network on one side and accesses the end user's devices in
FTTH, or FTTO, or FTTC service delivery architecture on the other side. The Cisco Catalyst PON Series
ONT communicates between the Cisco Catalyst PON Series OLT and the end-user devices.
In the upstream direction, a Cisco Catalyst PON Series ONT is connected to the optical splitter through the
PON port. The data, voice, and video signals from end user's devices are sent to the Cisco Catalyst PON Series
ONT. Using the uplink ports on the Cisco Catalyst PON Series ONT, these signals are converted into electrical
signals and transmitted over optical fibers to the Cisco Catalyst PON Series OLT. In the downstream direction,
the Cisco Catalyst PON Series ONT is connected to various end user devices using the G ports and provides
triple-play services such as high-speed internet (HSI), voice (VoIP), and video (IPTV and RF overlay).
