This document discusses GPON (Gigabit Passive Optical Network) technology. It provides details on GPON network architecture and components like the OLT and ONT. It then analyzes competition between major GPON equipment vendors like Alcatel-Lucent, Huawei, ZTE, and Ericsson. Their key GPON products are described and example deployments listed. Finally, the document shows Huawei, ZTE, and Alcatel-Lucent have the largest shares of the global GPON market, together commanding over half of all GPON lines.

1. GPON Introduction

2. 1. Technology Introduction
2. Competition Analysis
3. Market Share

3. Technology
• GPON: Gigabit Passive Optical Network is ITU-T G.984
standard
• It is an access method transported by optical fiber, FTTx.
Is a point to multipoint access, one central point can
reach from 32 to 128 premises. There are only two types
of equipments the OLT (central) and the ONT’s (in
customer premises)
• The other important part is the splitter, it is a passive
splitter that divides the signal as needed

4. Technology

5. Technology
• The ONT’s can vary according to what segment they are
intended to cover, residential, enterprise, triple play. That is why
usually for example for Enterprise the ONT can have several E1
ports to connect a PBX and one Ethernet to have data access
• The speed of the GPON ONT is a maximum of 1 Gbps DL and 1
Gbps UL, each GPON port have 2,5 Gbps DL and 1 Gbps UL
but is has to be distributed along the ONT’s and generally is
used over booking in order to use more efficiently the technology
• The latest new technology is 10GPON which increments the
speed of the link to 10Gbps DL and 2,5 Gbps UL

6. Competition Analysis
Diverse Market many manufactures the main ones are:
Alcatel-Lucent ISAM 7342 FTTU
Alcatel-Lucent’s ISAM 7342 FTTU platform has enabled the company to become a top
contender in the global FTTP market, with more than 100 customers to date, including
Verizon, France Telecom, Hong Kong Broadband and Australia’s NBN, Chunghwa
Taiwan, Finland government
Huawei MA5600T
Huawei remains #1 in the global FTTP/GPON markets on the strength of its
MA5600T OLT, which offers a very hard-to-beat price/performance proposition,
especially when combined with Huawei’s rapid product development/customer
support capabilities. Deployments in Etisalat, BT, Portugal Telecom, Claro
Argentina

7. Competition Analysis
ZTE ZXA10 C300
ZTE has caused quite a stir with its new ZXA10 C300 platform, which it touts as supporting
3.2 Terabits of backplane capacity. ZTE offers a complete FTTx solution. Deployments in
Telkom Indonesia, Telecom Italia, THEO Lituania, RDS &RCS Romania,
Ericsson EDA 1500
Ericsson’s EDA 1500 features very strong throughput-per-slot metrics, as well as
a 3.2 Terabit total capacity, but for Ericsson to reach its goal of being a top-three
vendor in the GPON market. Deployment in China Unicom, Bangladesh, AT&T,
Cyprus (Greece)
