4 Why Next Gen Access Networks? Benefits High bandwidth capability to subscribers to deliver video, voice and data services 1 and 10 Gbps options available in DOCSIS 3.1 networks and PONs 40 and 100 Gbps options being tested Improved overall reliability via PNM in DOCSIS 3.1 and optics with PON Knowledge of FTTx and DOCSIS 3.1 provides additional skills to cable installers and engineers, which can help open the door for new opportunities

5 DOCSIS 3.1 and FTTx Drivers Dial Up DOCSIS DOCSIS 3.0 DOCSIS 3.1/FTTx Next Gen 100 Gbps 400 Gbps * Billboard consumer speeds Maximum speeds today

6 What is FTTH? Fiber to the Home, or FTTH, delivers cable services over fiber optics. FTTH is also known as Fiber to the Premises (FTTP) FTTH delivers video, voice and data Optical fiber is used instead of coaxial cable Energy management and conservation Now available in more than 15 percent of homes; more than 9 million connected in North America High bandwidth capability to subscribers Offering 100 Mbps today 1 and 10 Gbps options available 40 and 100 Gbps options being tested

7 Benefits of FTTx FTTx improves efficiency by delivering cable services over fiber optics. Fiber to the premises is extremely cost effective in rural areas Improved overall reliability and reduced signal egress No power required for active devices and battery power supplies in the outside plant (OSP) Backup power for consumer premises equipment becomes the responsibility of the subscriber

8 Benefits of FTTx FTTx has many advantages by delivering cable services over fiber optics. An attractive option to coax, with customer perception that fiber is more valuable Fiber optimizes CapEx and reduces OpEx Optical fiber future proofs networks to allow for increased bandwidth over the same installed fiber Knowledge of FTTx provides additional skills to cable installers and engineers, which can help open the door for new opportunities

25 RFoG

26 What is RFoG? Radio Frequency over Glass Breaking it Down RF signals can pass through; air, coaxial cable and fiber optic strands RFoG can be viewed as coaxial glass, since only one strand is used for both forward & return paths, but on different wavelengths RFoG is a standard developed by the SCTE as SCTE 174 in 2010 to address the use of optical fiber to the premises Allows reuse of headend and consumer premises equipment RFoG spans from the headend, or hub, directly to the subscriber and use the same modulation schemes as HFC networks Optical Tap MicroNode R- MDU/Business 1550/1610 CM R- 1550/1610 CM 1550/1610 CM

27 RFoG Benefits Greenfield is less expensive than new HFC CapEx is spread across plant (60%) and subscriber (40%) Coaxial has 140 times the loss of fiber An economical solution for rural areas Typically lower maintenance costs no yearly sweep and no need for RF amplifiers approximately every 1000 Lower power needs, by as much as 75% in most cases, and some claim as much as 90% Typically, there are fewer trouble calls because there are no active devices from the headend/node Leakage in the downstream and ingress noise in the upstream is greatly reduced, if not eliminated

28 Even more RFoG Benefits! Preserves operator s investments Uses existing CMTS, laser transmitters, return path receivers, DOCSIS modems Uses current business processes and procedures for all services Supports DOCSIS 1.0 through 3.1 Seamless upgrade for customers and operators Other than the Passive Optical Network (PON) side, the same network architecture and initialization procedures in the headend/node and customer location are used Use additional wavelengths for PON overlay

52 What is DPoE? DOCSIS Provisioning of EPON (DPoE ) Specifications create an architecture and serve as necessary specifications for enabling Ethernet Passive Optical Network (EPON) equipment to be provisioned using existing DOCSIS based provisioning systems and policies, and to provide network services over EPON access networks to business customers. From the Specification Document DOCSIS Provisioning of EPON (DPoE) specifications are a joint effort of Cable Television Laboratories (CableLabs), cable operators, vendors, and suppliers to support EPON technology using existing DOCSIS based back office systems and processes. DPoEv2.0 specifications augment the DPoE v1.0 specifications to provide requirements for additional service capabilities and corresponding provisioning and network management capabilities.

53 DPoEv1.0 Specifications MULPI Specifications for support of a subset of DOCSIS MULPI functionality plus EPON requirements Architecture Defines the overall services architecture for DPoE Network Security (SEC) Provides transparent support of DOCSIS device authentication, code verification and additional security MEF Specifications for MEF services added to DOCSIS stat configuration provisioning model Ethernet OAM Extensions beyond IEEE 802.3ah and IEEE 802.3av OAM requirements DPoE v1.0 Specifications IPNE Best practices and requirements for IP network element management and operations OSSI Specs for support of a subset of DOCSIS 3.0 OSSI functionality with additional EPON Requirements DEMARC Specification for automatic configuration of demarcation device PHY Options within EPON declared mandatory and adds additional requirements
