There was a lot related to 100-Gbps discussed at OFC 2014 in San Francisco, and Lightwave Editorial Director Stephen Hardy summarizes the highlights in this final podcast in our series. Topics include pluggable coherent CFP and CFP2 modules for the line side, new DSPs for such applications, and other enabling technologies, such as integrated coherent transmitters and integrated coherent transceivers. The client side gets its due as well, with a look at the advent of CFP4 modules and action within the QSFP28 form factor. Emerging optical transceiver MSAs for data center applications of around 1-2 km also are covered.

Pluggable coherent 100G modules are a significant topic of conversation here at OFC 2014. But what are the prospects for their adoption? Vladimir Kozlov, founder and CEO of market research firm LightCounting, discusses his company’s market figures for coherent 100G for 2013, his expectations for 2014 and beyond, and how large a portion of port market share modules might fill.

Lightwave Editorial Director and Associate Publisher Stephen Hardy talks with Avi Shabtai, CEO of MultiPhy, the leading provider of silicon that supports 100-Gbps transmission using direct detection, rather than coherent detection. Shabtai offers his viewpoints on who the demand for 100G direct detect has evolved, whether the advent of metro-focused coherent 100G pluggable transceivers will threaten the market for direct-detect options, and whether there’s a future for direct detect at speeds greater than 100G.

Alcatel-Lucent is focusing on “Moving Metro Forward” at OFC 2014. Lightwave Editorial Director Stephen Hardy speaks with Alcatel-Lucent IP Transport Marketing Leader Kevin Drury about what this means in the context of 100-Gbps transmission. Along the way, Kevin discusses strategies for reducing the cost of 100G for metro applications, whether Alcatel-Lucent would ever be interested in a pluggable coherent transceiver, and what the prospects for 200G and 400G in the metro might be.

Lightwave Editorial Director Stephen Hardy interviews Ron Kline, principal analyst, network infrastructure at Ovum, about 100G’s market traction in 2013 and his expectations for 2014. Ron offers his opinions on the opportunity for 100G in the metro, as well as for the prospects for 200G and 400G.

Lightwave Editorial Director Stephen Hardy quizzes John Calvin, BERT portfolio manager at Tektronix, about the challenges technology developers are likely to face working in applications with data rates ranging from 25G to 28G. The three primary applications are the OIF CEI interfaces, InfiniBand, and IEEE 802.3bj. While they have aspects in common, each application also presents unique challenges that must be addressed.

Jimmy Gagnon, product specialist at EXFO Inc., discusses the latest trends in FTTx test and measurement with Lightwave Editorial Director Stephen Hardy. Topics include developing requirements within FTTx test, the evolution of FTTx test instruments, and strategies for lowing FTTx test costs.

Sujan Sami, Measurement & Instrumentation Program manager for market research firm Frost & Sullivan, talks to Lightwave’s Editorial Director Stephen Hardy about the major trends in fiber-optic test and measurement equipment. He estimates the size of the fiber-optic test and measurement market and discusses the major trends in the optical network test space. These include the influence of coherent transmission as well as increased data rates in carrier and enterprise/data center fiber-optic networks. He also offers his expectations for consolidation in the fiber-optic test and measurement space.

With high-speed optical transceivers evolving quickly into smaller form factors with different requirements, test and measurement tools and procedures must keep pace. Lightwave Editorial Director Stephen Hardy met with Dr. Paul Brooks of JDSU’s Network and Services Enablement Group at ECOC 2013 recently to discuss the evolution from CFP to CFP2, what the test requirements of CFP4 might be, and what the future holds for transceivers designed to support eventual 400 Gigabit Ethernet specifications.

Lightwave Editorial Director and Associate Publisher Stephen Hardy provides an overview of the announcements and discussions of 100G at the ExCeL in London that he found most significant.
