“Third Party Optics” enabling 100Gbps for the entire backbone

A new era of networks is about to begin on a global scale, with the commercialization of 5G, the fifth-generation mobile communication system, starting overseas. Established in 2000 as Japan's first specialized Internet data center operator, we are focusing on creating an environment to provide the high-performance data center infrastructure and broadband Internet backbone required in this era. It is BroadBand Tower Co., Ltd. (hereafter, BroadBand Tower).

As part of its efforts to create an environment suitable for the new era, the company undertook a complete renewal of its existing Internet backbone.

In August 2018, Broadband Tower established a new ``New Otemachi Site'' in Chiyoda Ward (Otemachi District), Tokyo, the center of the internet in Japan, which claims to be a data center for the 5G era. We carried out renovations. Regarding this background, Akihiro Mizuochi, Director of System Design Group and Network Design Group of the company's Technical Design Division, says the following.

“As the new plans for the Shin-Otemachi site were progressing, the existing internet backbone was reaching the end of its useful life.Therefore, we decided to create a broadband, low-latency network environment that would be compatible with 5G environments. We carried out a complete network renovation, including switches and routers."

In particular, this renovation aims to create a ``modular backbone'' that can flexibly respond to customer company requests and changes in the environment by introducing a large number of small routers and switches that can support both 100Gbps and 10Gbps. Optical transceivers manufactured by Finisar Corporation (hereinafter referred to as Finisar) provided by Macnica are used in parts of the network, including the Internet backbone. The company chose Finisar because it was difficult to meet the requirements for the new network setup with genuine manufacturer's products.

"The modular network we aimed for has a high degree of freedom in that it can be scaled out/up flexibly. For example, we can flexibly make changes such as upgrading from 10Gbps to 100Gbps according to customer requests. was one of the themes.Then, we considered 'Third Party Optics,' which we could easily control.'' (Mr. Mizuochi)

In addition, Ryosuke Kato, a professional at Broadband Tower Cloud & SDN Research Institute, who handled everything from in-house proposals to RFP creation for this network renewal, said, ``In order to create an optimal network within a limited budget, we need to We thought that ``Party Optics'' was the best option,'' adding to the reason for choosing it from a cost perspective.
