This document describes the hardware and software requirements, features, and bugs for the Cisco Catalyst PON Series Optical Network Terminal (ONT).


Note

The documentation set for this product strives to use bias-free language. For purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on standards documentation, or language that is used by a referenced third-party product.

Introduction to Cisco Catalyst PON Series Optical Network Terminal

Cisco Catalyst PON Series switches are built to address the emerging demand of bandwidth for enterprise and residential users. A network designed using the Cisco Catalyst PON Series switches in the campus replaces a three-tier architecture with a two-tier fiber optic network. It eliminates the active access and distribution Ethernet switches with passive optical devices.

An Optical Network Terminal (ONT), also referred to as an Optical Network Unit (ONU), is an integrated PON access device to which the end users are connected. It provides high performance access services for end users, Small Office Small Home (SOHO) users, small companies, cable TV (CATV), audio and video transmission, and networks where shared high-speed internet access is required.

What’s New in Cisco Catalyst PON Series ONT, Release v1.1.3.18

Bug Fixes.

What’s New in Cisco Catalyst PON Series ONT, Release v1.1.3.17

Feature

Description

Applicable Models
Support for Single Family Unit (SFU) mode

Beginning with this release, the CGP-ONT-4PVC and CGP-ONT-4PV models can operate in the SFU mode too.

You can switch to SFU mode by navigating to Administration > Reboot on the Web Management interface and selecting the Change to SFU option. For more information, see Cisco Catalyst PON Series Switches ONT Configuration Guide

Note 

Downgrade of the ONT firmware release from v1.1.3.17 to an earlier one is not supported on CGP-ONT-4PVC and CGP-ONT-4PV models. This is because a new device type is introduced on these models to support the SFU mode.

For more information, see CSCwa10507.
