▼Overview

NTT EAST is boldly shifting its management resources to expand its scope ofbusiness based on a locally focused organizational system. The number of contracts
for the optical access service involving the Hikari Collaboration Model topped 4 million
in August 2016, and NTT EAST is aggressively pursuing initiatives for revitalizing
regional economies under the banner of new business creation. We asked Senior
Executive Vice President Motoyuki Ii to tell us about this major change in thecorporate mindset and the actual efforts underway to make this change a reality.

Initiatives for the Widespread Adoption of NetroSphere

Accelerating the Demonstration and Adoption of NetroSphere▼Abstract

The NTT Group aims to accelerate the transformation to abusiness-to-business-to-X (B2B2X) business model in response tochanges in the telecommunication market. NetroSphere is theconcept of a flexible and robust network that can cope with diverseand uncertain demand in the B2B2X model. The Feature Articles inthis issue introduce the development of the network architectureand network systems technology that advance the materialization ofthe NetroSphere concept. It also touches on NetroSpherePIT and the global rollout to carriers and vendors
as a collaborative program for accelerating the implementation of this concept.

Spatial and Planar Optical Circuit (SPOC) Technology andIts Application to Photonic Network Devices▼Abstract

Because photonic networks have evolved from point-to-point systems toring or mesh networks, higher scalability is required in the devices used inoptical nodes. Hybridization of waveguide and free-space optics or spatialand planar optical circuits (SPOCs) may provide the necessary solutions tomeet this requirement. A SPOC platform is attractive because it can takeadvantage of both waveguide technology and free-space optics. Waveguide technology provides a highdegree of integration of optical functionality for such devices as splitters and non-wavelength selectiveswitches, while free-space optics supplies a high degree of parallelism with two-dimensional spatial light
modulators such as liquid crystal on silicon (LCOS) devices. In this article, we summarize the basics of SPOC
technology and review its application to reconfigurable optical add/drop multiplexing (ROADM) devices.

Ethernet Private Line System with World’s Highest Quality(Bandwidth Guarantee, High Availability, and Low Delay)▼Abstract

Virtual private networks and broadband Ethernet are increasingly being
used as corporate wide area networks. Consequently, demand is growingfor higher availability and lower delay in addition to the bandwidth guaranteeand carrier-grade maintainability and operability of conventional digital
private line systems. We describe here an Ethernet private line system that
achieves the world’s highest level of quality to meet that demand.
