Innovative optical fibers and cabling may offer providers and enterprises substantial benefits for connecting data centers across a wide range of distances while simultaneously using newer technologies that reduce range.
The critical challenge facing operators today is to deliver sufficient capacity in their networks to allow customers to properly access data-heavy applications and services such as live video calling, high-density video streaming and virtual/augmented reality, according to the last report from NGON & DCI Europe's three-part series, "Fiber and Cable for the Cloud." Not only are these applications drawing data at higher rates, many households frequently run several active devices simultaneously putting pressure on the network to consistently deliver high quality of service.
Operators respond by migrating to more spectrally efficient modulation schemes that extend capacity at a lower cost per bit. Because of these trends, very high fiber-count cables (more than 3,000 optical fibers) become essential for connecting hyperscale data centers within a campus over distances of less than 10km. Indeed, 200G is now established and 400G is emerging -- but this progression can lead to a practical trade-off in reach, this series of reports shows. That is, 200G 16-QAM operation limits practically achievable reach to less than 1000km and 400G 64-QAM to less than 100km.
Installing fiber with ultra-low loss (ULL) ensures the optical-signal to-noise-ratio (OSNR) at each amplifier is elevated, allowing operators to add more spans before performance is degraded to the point of generating errors at higher data rate protocols. Put simply, the capability delivered by ultra-low loss fiber allows operators to transmit more data over longer distances with less equipment and lower installation, land acquisition and maintenance costs.
In metro DCI scenarios, ULL fibers can extend network reach, ultimately empowering data centers to relocate to areas with cheaper real estate that are nearer to renewable energy sources. And when ULL is combined in a fiber with larger effective area, even longer spans and reach are enabled as providers launch higher power signals before introducing performance degradation due to non-linear signal distortions.
In "To 400G and beyond," experts explore the arrival of the 400G era which lets operators squeeze yet more bits from their network assets. The report dives deeper into the state of next-generation optical networking as technologies and deployments ramp up from 100Gbit/s to 400Gbit/s and beyond. Get your free copy.

On Jan. 23, Broadband World News hosts a Calix-sponsored webinar that explores several ways CSPs can enhance customer experience and find new business opportunities to avoid devolving into a speed race where nobody wins, not even the customer.
The lack of an accurate broadband map means states and counties are tackling this issue themselves – and sometimes finding big disparities in the data – before spending their residents' money on deploying infrastructure.
Next year many operators must decide whether to invest more in HFC or go all-in to fiber, pick their PON and choose their managed-WiFi path, writes analyst Dan Grossman, who also recommends providers bundle managed WiFi and analytics to best serve residential subscribers -- and operators' own businesses.
Public-private partnerships, investor interest, self-help in rural areas and incumbents' return set the scene for a busy year of broadband deployment in the US countryside in 2020, writes Analyst Dan Grossman.
It wasn't long ago that TV was ranked by subscribers as the most important service in the bundle provided by their communications service provider (CSP). Recent research indicates that for nearly three quarters of subscribers, broadband is now the most important service. Broadcast TV is the most important service to only 15% of North American consumers, replaced by OTT video streaming platforms like Netflix, Amazon Prime and Disney+. In addition, many different competitors are moving aggressively to stake a claim in consumers' homes.
In 2020, CSPs need to fight back by transforming their business models, which are becoming more reliant on a single source of revenue: fixed broadband services.
This webinar will focus on helping CSPs transform their business models by placing a firm focus on delivering a sensational subscriber experience and by offering compelling new services that generate value for subscribers. These actions will reinforce the CSP's strategic position in the home network and position themselves for growth in the next decade.
Key topics include:
Being the first to market with WiFi 6 technology, in response to consumer purchases of new devices over the holidays;
Having the insights needed to proactively resolve issues, often before your subscribers even know that there are issues;
Providing help desk agents with the visibility they need to resolve common subscriber issues more quickly;
Delivering a mobile app, in response to consumer demands for the ability to do some things themselves, rather than having to call technical support; and
Addressing consumer concerns around device security, privacy and control with enhanced security and parental controls.
In this insightful Light Reading radio show, Kurt Raaflaub, Head of Strategic Solutions Marketing, will outline the key service provider challenges, deployment considerations, next-gen Gigabit technologies, and service models to win market share in the rapidly growing MDU market.
