Introduction
Split Ratio
Split ratio is the ratio of dividing a downstream optical signal into sub-
signals in the PON system. Greater optical ratio requires more power to
support physical distances.

Introduction
U-PE
User-end provider edges (U-PEs) are routing devices directly connected
to customer edges (UEs). U-PEs support routing and MPLS
encapsulation. If a U-PE is connected to multiple CEs and possesses the
basic bridging function, data frame forwarding only needs to be
performed on the U-PE. This reduces the load of the S-PE.
PE-AGG
Aggregation provider edge (PE-AGG) routers provide aggregation and
route forwarding functions for access equipment. Compared with U-
PEs, PE-AGGs features higher performance, fewer interfaces, and
higher switching rates.
NGN/IMS
A next generation network (NGN) is a network that uses softswitches
as its core and uses open and standardized architectures to provide
abundant services such as VoIP, video, and data.
The IP multimedia subsystem (IMS) uses SIP signaling as its call control
signaling to provide services such as VoIP, data, and multimedia
services.
NOTE
NGN/IMS in this document refers to softswitches that support H.248 and SIP.
IPTV head end
The IPTV head end system functions as the contents preparation
platform in the IPTV system. It provides functions such as signal receipt,
media format conversion, and media material management.
12.1.2 Networking Scenario and Hardware Configurations
This section describes the typical networking scenarios for small office and home office (SOHO)
users and small- and medium-sized enterprises (SMEs) in GPON access mode in fiber to the
office (FTTO) scenarios, as well as the typical hardware configurations of optical line terminals
(OLTs) and optical network units (ONUs).
