90 | BROADBAND COMMUNITIES | www.broadbandcommunities.com | JULY 2015 TECHNOLOGY Optical Fiber in the Living Unit The advantages of indoor ONTs have a created a need to place fber inside living units. The challenge: installing the fber invisibly with no disruption to residents. By Anurag Jain and John George / OFS D uring a recent fber-to-the-home installation in Brazil, installers heard feedback that has become familiar over the years. "We don't want to see it," said an 18-year-old resident, frmly paraphrasing his mother's instructions to the installers. And he added another requirement often heard from residents in solid concrete buildings: "Tere can be no drilling or damage to any of the walls." After the installers promptly explained the process and showed the InvisiLight indoor optical fber kit, the young resident had no difculty understanding the simple process or envisioning the attractive result, and he gave the installer the green light to proceed under his watchful eye. Fiber-to-the-home (FTTH) and fber-to-the- business (FTTB) deployments are accelerating globally, and 147 million subscribers are now fber-connected. Te current trend is to install optical fber inside a living unit to an indoor optical network terminal (ONT), which requires fber in the home (FITH). OFS launched the InvisiLight solution in 2012 to enable fast, virtually invisible fber installation to indoor ONTs. Today there are more than 50,000 InvisiLight installations worldwide in multiple-dwelling-unit properties, residential single-family units and business premises. An indoor solution of this kind diferentiates a provider's service ofering, improves subscriber acceptance (which yields a higher take rate) and speeds up time to revenue for the service provider. Figure 1 shows an example of an InvisiLight installation map and actual provider installation pictures. ADVANTAGES OF FIBER IN THE HOME Service providers are increasingly locating an ONT inside each living unit to help meet the growing need for speed. Many providers now deliver a gigabit connection to each subscriber, and some plan to ofer 10 Gbps connections in the next generation. Content providers, such as Netfix, recommend a 25 Mbps connection to accommodate a single 4K video stream. Soon to come is 8K video, with possibly 50 to 100 Mbps recommended per stream. In addition, the number of connected devices per home is projected to quadruple in the next fve years, and even more bandwidth will be needed per device for consumer and business applications. Te number of devices that will support streaming video, voice, security video surveillance, data, gaming or home and appliance automation is projected to increase from fve today to 20 per household by 2020. Cost and wireless coverage are also driving fber into the home. When fber is run to an Running fber to an ONT centrally located inside a residence enables the provision of excellent Wi-Fi coverage and bandwidth to many in-home devices.
