1 INTRODUCTION 1.1 About Corning Optical Network Evolution (ONE™) Solutions ™ Corning optical network evolution (ONE ) provides an all optical converged solution which provides a flexible in-building cellular and network data coverage solution based on a fiber optic transport backbone. Fiber-to-the edge technology allows for virtually unlimited bandwidth to support today and tomorrow’s growing demands of wireless users.
1.3 Basic System Architecture Broadband RF distribution over fiber-optics infrastructure transfers converged wireless services from the IHU at the headend towards the MRUs deployed at the remote-end locations according to user defined configuration. The IHU is a compact unit designed to accommodate small/medium size deployments.
1.4 User Controlled Service Group Distribution ™ Corning optical network evolution (ONE ) solutions fiber-optics infrastructure allows various combinations of wireless services to be routed from the headend to specified remote locations on each floor, according to user defined configurations. This allows optimizing service coverage and provides equipment savings. While the fiber-optics infrastructure is common, the services can be routed via service provider shared or dedicated equipment.
1.4.1 Service Distribution via One Service Group In this example, all four services (A, B, C, and D) are routed to all remote units. In the illustrated topology, a single IHU conditions the services and performs the RF-to-optic conversion after which all the configured services are routed to the remote units for distribution over broadband antennas. Each IHU can support up to 24 remote-end units. Figure 1-3.
1.4.2 Service Distribution via Two Service Groups In this example, two service groups are defined: SG#1: A,B,C and SG#2: C,D. When configuring a service group, the user selects which services (according to RIMs) will be routed to which OIMs and then transferred over their optic links to their hosted remote units for distribution. Figure 1-4.
1.4.3 Service Distribution via Three Service Groups In this example, three service groups are defined: SG#1: ABC, SG#2: AB, and SG#3: CD. Note that a service can be allocated to any of the service groups at the same time. For example, services C and B are allocated to two of the service groups. The services are routed to the OIMs for optic conversion.
1.5 Web Management Application The headend control module (HCM) enables centralized, system-level element management and provides comprehensive end-to-end, single source setup and management of the active RF components after their physical installation. Note: Refer to the Corning optical network evolution (ONE™) solutions HCM and Management GUI user manual for a complete description of the Web management application. Figure 1-7 shows the Management window, displayed by default upon login. Figure 1-7.
