54 | BROADBAND COMMUNITIES | | AUGUST/SEPTEMBER 2016 TECHNOLOGY Innovative Fiber Design In Longmont When a community deploys fiber, the process must be cost-effective, fast and flexible. Here's how Longmont, Colorado, achieved all three goals. By Johnny Hill / Clearfield Inc. M ore than 100 years ago, the city of Longmont, Colorado, bucked the trend and built its own electric power network, Longmont Power & Communications. Today, Longmont has 90,000 citizens in more than 33,000 households, and it is again forging its own path, building out a community owned and operated gigabit fiber optic network to provide fiber-to-the-home services to every home and business within its borders. NextLight is the only 100 percent fiber optic network in Longmont. Fiber all the way to the home ensures the network will meet residents' requirements today and well into the future. In 2015, the NextLight internet service was the fastest in the nation, according to speed testing company Ookla. Longmont's challenge was to make the network • Cost-effective to design and deploy • Quick and easy to install to generate service revenue as soon as possible • Flexible enough to accommodate other projects happening in the city at the same time and any adjustments made from the time of the initial project plan to the last fiber installation. Longmont found there are a lot of moving parts in a fiber deployment, as there are in many large-scale construction projects. By using a rolling design process, in which the design of each stage is finalized just in time for its construction, the city was able to keep progressing despite the need to accommodate design and requirement changes along the way. rough this process, Longmont realized the value of working with products – and partners – that are flexible and can adapt to the needs of customers, environments and budgets. DESIGNING FOR SUCCESS AND COST-EFFECTIVENESS Uptown Services, a design and engineering firm based in Boulder, Colorado, explored two architectures for Longmont's fiber network: a centralized split architecture and a distributed split architecture. ese two network design alternatives offer different benefits, and because every fiber deployment has unique circumstances and different expected customer take rates, the flexibility to choose the architecture that matches the job at hand is important. A centralized split architecture is best used when the take rate is unknown. In this architecture, a fiber distribution hub (FDH), The flexibility to choose the architecture that matches the job at hand is important because different alternatives offer different benefits.
