3 What do EPONs Transport? Host An Ethernet Passive Optical Network transports Ethernet signals between a host and a client Client 3

4 What do EPONs Transport? Host An Ethernet Passive Optical Network transports Ethernet signals between a host and a client Client Ethernet is sometimes confused with Internet, which is a service that rides on the Ethernet packets Ethernet transport is also referred to as transporting IP data, or Internet Protocol data 4

5 Transporting Ethernet Signals Our desktop computers are often connected with a CAT-5 cable to a Router or Switch We use Ethernet links every day We use wireless links between our laptops, ipads and Kindles to exchange Ethernet information In offices, we have CAT-5 cables that link to computers via switches and routers to mainframe switches that collect the user, or client, signals and route them internally or consolidate them at the internal host. There, the consolidated signals are sent outside the building on backhaul links to major IP network providers. 5

6 Comparing Ethernet Networks Ethernet Network Consider a CAT-5 cable connecting to an RJ-45 Jack on one end of our network, and another RJ-45 Jack at the other end of our network connecting to another CAT-5 cable. This will be the baseline for our comparison of several different forms of Ethernet Networks. 6

7 Home Ethernet Network Home Ethernet networks include wired and wireless Wired connects the cable modem to other Ethernet interfaces through a router Wireless converts the Ethernet signal at the router into an RF signal that is broadcast/received and converted back to Ethernet at the user device 7

8 Cable Operator Ethernet Network Cable operators begin transporting Ethernet data streams to subscribers by taking Ethernet signals from a switch in the headend or hub and feeding them into the Cable Modem Termination System CMTS The CMTS converts the signals to RF and they are transported over the HFC network to the subscriber s Cable Modem, where they are converted back to Ethernet and are available at the RJ-45 Jack 8

11 Media Converters Media Converters (MC) simply use fiber optics to replace point-to-point Ethernet connections 100Mbps via dedicated fiber HE MC to Sub MC about $700 per sub 1Gbps via dedicated fiber HE MC to Sub MC About $1,700 per sub 1Gbps via shared fiber HE CWDM MC to Sub CWDM MC about $2,700 per sub at 4 subs per fiber 11

12 ActiveE, P2P and MetroE Architectures ActiveE, P2P Dedicated-Fiber Architecture Maximum fiber count More OSP equipment than PON - Enclosures, ducting, etc Dedicated TX/Rcvr per customer P2P Architecture MetroE, P2P Dedicated-Fiber Architecture Same as ActiveE but dedicating wavelengths Two dedicated wavelengths per customer Fewer fibers than ActiveE Same number of TX and Rcvrs as ActiveE Router X-Conn 12

13 PON History PON grew out of a need by the Telecom industry for Dramatically more bandwidth to subscribers Replacing aging copper infrastructures Reducing power requirements Reducing OPEX costs Proven Technology First standards developed in 1995 ITU and IEEE standards-based 15 years of investment in perfecting PON technology The number of PON ONT shipments is forecasted to reach 24.5 million by

14 PON History FSAN starts first format PON activity. 155Mbps APON ITU G.983 series Enhanced to BPON 622/155Mbps with 3 rd lambda, protection and DBA EFM starts work on ah incl. EPON FSAN starts GPON work G.984 series = extension of G.983 series, up to 2.4Gbps ITU approves GPON EPON ratified by IEEE 14

15 Why PON? Security Converges voice, video, data and building automation onto a single fiber No electronics between the data center and the desk Green IT No EMI emissions Centralized and secure administration Improved reliability Reduced installation time and costs Reduced operational and training costs Enhanced network performance Eliminates the active distribution layer of switches No need for backup power or special cooling in riser closets As future technology evolves only the endpoints need upgrading Lower cost Less power Less space 15
