1 Internatinal Telecmmunicatin Unin ITU-T Technlgies and applicatins f Passive Optical Netwrks (PON) Yuki Nakan Hitachi ITU-T Wrkshp NGN and its Transprt Netwrks Kbe, April 2006

2 5M FTTH Penetratin in Japan Number f FTTH users 4M 3M 2M 1M B-PON intrductin Sept June Dec June Dec June Dec June Dec Surce: Ministry f Internal Affairs and Cmmunicatin, Japan ITU-T Wrkshp NGN and its Transprt Netwrks Kbe, April

3 PON Technlgies Optical splitter (passive) Bi-directinal transmissin ver ne fiber using WDM 1490nm CO 1310nm OLT Upstream packet multiplexing n fiber withut cllisin Cre Netwrk ITU-T Wrkshp NGN and its Transprt Netwrks Kbe, April

4 PON Advantages Very high speed data up t 1 Gbit/s t hme and businesses Maintenance cst reductin due t n electrnics between CO and custmers Lw cst due t fiber and CO interface shared by several custmers Cnstant data rate regardless f reach Multiple applicatins including data (IP), vide and vice (triple play) ITU-T Wrkshp NGN and its Transprt Netwrks Kbe, April

5 Bradband Internet applicatin FTTH in Japan started frm simple applicatin f IP/Ethernet and it is still dminant Simple indr enabling ecnmical Bradband access f 100 Mbit/s best effrt service The service is like simple extensin f ADSL Hme CO OLT Internet ITU-T Wrkshp NGN and its Transprt Netwrks Kbe, April

6 Triple play with RF vide RF verlay using WDM prvides cnventinal CATV type vide service in additin t Bradband Internet Very ppular in Nrth America Hme r Business Data Vice RF vide ONT Dwnstream Data + RF vide Upstream Data Central Office WDM OLT Vice Netwrk Data Netwrk RF Vide ITU-T Wrkshp NGN and its Transprt Netwrks Kbe, April

7 IP triple play applicatin Hme Gateways t separate IP vide and prvide POTS cnversin Entire netwrk based n IP and Ethernet Hme CO Vice Netwrk Hme Gateway OLT Vide Netwrk Data Netwrk ITU-T Wrkshp NGN and its Transprt Netwrks Kbe, April

8 PON Cmparisn B-PON GE-PON G-PON Standard ITU-T G.983 IEEE 802.3ah ITU-T G.984 Dwnstream data rate 600 Mbit/s 1 Gbit/s 2.4 Gbit/s Upstream data rate 150 Mbit/s 1 Gbit/s 1.2 Gbit/s Transmissin Frmat ATM Ethernet Ethernet + TDM +ATM (Nte) Rates f cmmn practice.

9 Why GPON nw? Standardized by telecm peratrs and telecm vendrs in ITU-T Varius peratin and management capability inherited frm cnventinal prved telecm technlgies Future-prf bandwidth 2.4 G / 64 users = 35 M per user 35 M = 6 M (HDTV-MPEG4) x 4 ch + 10 M (Internet) Suitable fr business users because f varius QS and bandwidth management ITU-T Wrkshp NGN and its Transprt Netwrks Kbe, April

10 GPON example (Single Family Unit) IPTV systems 100M 2.4 G 1.2 G OLT 10G/1G Internet 100M 1G 20 km (Multi Dwelling/Tenant Unit) VIP systems ITU-T Wrkshp NGN and its Transprt Netwrks Kbe, April

11 Pssible Future Directins Technlgy available and massive GPON deplyment sn IP HDTV service in near future Mre bandwidth by higher transmissin rate r WDM technlgy Lnger reach by ptical amplifier Higher splitter rati (mre users per PON) by ptical amplifier ITU-T Wrkshp NGN and its Transprt Netwrks Kbe, April

12 Cnclusin B-PON initiated the first massive PON rllut in Japan PON technlgy is suitable fr triple play services (vice, vide, data) Future-prf G-PON technlgy available and sn t be deplyed massively ITU-T Wrkshp NGN and its Transprt Netwrks Kbe, April
