Emerging Subsea Networks: The Search for High Capacity and Long Reach

To support the exponential growth of global data traffic, 100 Gb/s submarine transmission systems are being installed in transoceanic links. These systems offer capacity up to ~10 Tb/s on a single core fiber using a C-band Erbium doped fiber amplifier (EDFA).

However, there are distinct challenges involved in developing and deploying high-capacity transoceanic distance transmissions systems. One issue is the need to improve optical signal-to-noise ratio (OSNR) within the entire C- and L-bands.  Another limitation lies in delivering electrical power to the offshore equipment supplying EDFA pumps.  In addition, long haul undersea submarine systems are typically much longer than terrestrial systems and have unique requirements for fiber optic cables and repeaters used in harsh subsea environments.

In a new white paper presented at SubOptic 2016, OFS and OFS Labs researchers discuss key fiber and amplifier technologies that help users to achieve high capacity and long reach for submarine transmission systems. These technologies include ultra-large-effective area, low loss optical fibers and their impact on performance, along with key amplification techniques for both repeatered and repeaterless submarine systems.

The Heat Is On

The commercial use of optical fiber in harsh environments is continually growing.  These applications include medical probes that undergo sterilization at elevated temperatures and distributed sensors in oil and gas pipelines and wells exposed to extreme heat and cold.  For these fibers to be used successfully, researchers and manufacturers must address the issues of fiber performance and reliability under the harshest conditions.

However, current theories and knowledge on the strength and dependability of silica-based optical fiber have been based almost exclusively on experiments conducted in optical telecommunications environments.  Moreover, these tests only used a relatively narrow range of temperatures.  For usage in extreme environments, fiber developers and users need new data and information.

In a recent white paper from OFS Specialty Photonics, researchers describe a setup for testing the tensile strength of optical fiber when exposed to high temperatures.  This paper also reports the initial results of dynamic tensile strength testing conducted on polyimide-coated optical fiber at elevated temperatures over various time intervals.

Gimme Fiber!

On November 4, the FTTH Councils will celebrate “Gimme Fiber” Day. This annual event showcases the positive impact that optical fiber has had on communities around the world, and what global policymakers can do to help advance the expansion of fiber optic networks.

To help commemorate “Gimme Fiber” Day, the FTTH Councils will sponsor a series of activities including hosting an event in a city that has deployed a fiber network. This event will highlight the many benefits of that particular network and also the role that fiber deployment has made in bringing countless communities into the 21st century.

If your city is interested in hosting the 2016 “Gimme Fiber” Day, you can learn more about this event and download an application by CLICKING HERE. The deadline for application submission is May 15, and the winning venue will be announced at the FTTH Connect in Nashville on June 13-15.

 

OFS Labs “Tech Talks” Hollow-Core Optical Fiber

It’s not easy to confine light to an air core fiber using traditional guidance  guidance methods e methods such as total internal reflection.

In a new Tech Talk presentation, Brian Mangan of OFS Labs discusses the characteristics of hollow-core single-mode fibers. He also demonstrates the attenuation dependence of these fibers and how, using fibers that guide light in air, users can extend the wavelength range of silica fibers out to the infra-red.

How ADSS Cable “Lost the Gel”

Over the past decade, the fiber optic industry developed and quickly accepted the use of completely gel-free (“dry”) loose tube cables for general use. Referred to as “dry-dry,” these cables use superabsorbent powders to prevent water ingress into a cable instead of traditional oil-based filling and flooding compounds. Now completely gel-free technology has arrived in the ADSS cable arena.

On March 18, Dr. Tim Goddard of OFS will present an IWCS-sponsored webinar on the development and commercial deployment of a totally dry ADSS loose tube cable family. This presentation will cover the key design factors considered in development and the comprehensive test program performed to ensure the suitability of these cables for use in the field.

Making the Right Optical Fiber Choice: Single-Mode or Multimode?

Cloud computing and web services continue to drive the need for greater network bandwidth. In fact, this demand is pushing the data communications rates for both enterprise and data center networks up to 100G and beyond.

Given these higher speeds in mind, premises system designers may believe that single-mode fiber holds a growing advantage over multimode fiber. However, higher Ethernet transmission speeds alone do not automatically make single-mode fiber the right choice.

Network developers must consider a variety of factors such as bandwidth, reach and cost-effectiveness. And, with the introduction of bend-insensitive fiber and Wideband Multimode Fiber, it makes sense to revisit the Issue of multimode versus single-mode fiber.

A new white paper by OFS’ Tony Irujo offers a fresh perspective on making the right fiber choice for your premises network.

OFS Launches New Addition to Fiber Optic Microcable Product Line

OFS introduced the newest member of its growing microcable product line at the FTTH Conference in Luxembourg today.  Building on OFS’ expertise in microcable technology, the MiDia® 2GX Cable can help take metropolitan networks to the next level with increased fiber density, enhanced performance and significantly greater cost-saving opportunities on deployment.

Specifically designed for seamless installation into existing microduct networks, the MiDia 2GX Microcable can help service providers achieve up to a 100% increase in fiber density plus longer air-blown installation distances, by using a single, reduced-diameter cable.
