Operator agreements catalyze FTTH builds in France’s low-density areas

After implementing a policy for fiber installation and network sharing in urban apartment buildings, France has embarked on a plan to bring fiber access networks to the country’s...

2012 optical industry trends

If the 2011 calendar year could be described in three words, they would be “explosive bandwidth growth.” Both wired and wireless networks were stretched as consumers continued to adopt...

Ensuring cloud computing performance on data communications networks, Part 2

In Part 1 of this three-part series on cloud computing, we introduced you to the concept of reference points (RPs) as a means for software designers and network architects to better understand and...

Sub-Sahara Africa submarine capacity to exceed 20 terabits in 2012

The past few years have witnessed a spike in the submarine cable construction that began a decade ago with projects to circle Africa with international cables and provide terrestrial links to...

The evolution in packet-optical transport systems

The tremendous growth of data services over the last several years has resulted in unprecedented bandwidth and capacity challenges for operators. In response to these challenges, infrastructure...

Ensuring cloud computing performance on data communications networks: Part 1

Cloud computing promises to reduce IT expenditures, increase network flexibility, and streamline communication infrastructure. This is the first in a series of three articles in which we will...

Optical transceivers for 16G Fibre Channel: Improving performance in storage-area networks

Cloud services and storage have exploded in popularity, enabled in part by virtualization technology at the server, the desktop, and in the storage-area network (SAN). For example, the multi-core...

Is there a place for FBG-based dispersion compensation in high-bit-rate optical transmission networks?

The continued evolution and growing use of high-bandwidth services should continue to drive the need for increases in optical network capacity for several years to come. Today 40G systems are being...

The case for field-terminated mechanical connectivity

The drop cable connection serves as a key component in fiber-to-the-home (FTTH) networks. Reliable broadband service depends upon subscriber drops that are stable, efficiently installed,...

Modular vs. conventional oscilloscope approach for optical coherent modulation analysis

Modern day high-bandwidth conventional oscilloscopes are typically supplied with a maximum of four input channels (and with as few as one or two channels at a higher bandwidth rating), owing to...
