Telefónica tackles video growth with IP-MPLS network

• Telefónica’s video growth in one year has matched nine years of IP traffic growth 

• Optical mesh network in Barcelona will use CDC-ROADMs and 200-gigabit coherent line cards 

Telefónica has started testing an optical mesh network in Barcelona, adding to its existing optical mesh deployment across Madrid. Both mesh networks are based on 200-gigabit optical channels and high-degree reconfigurable add-drop multiplexers (ROADMs) that are part of the optical infrastructure that underpins the operator’s nationwide IP-MPLS network that is now under construction.

Maria Antonia CrespoThe operator decided to become a video telco company in late 2014 to support video-on-demand and over-the-top streaming video services.

Telefónica realised its existing IP and aggregation networks would not be able to accommodate the video traffic growth and started developing its IP-MPLS network.

Is the tunable laser market set for an upturn?

Part 2: Tunable laser market

"The tunable laser market requires a lot of patience to research." So claims Vladimir Kozlov, CEO of LightCounting Market Research. Kozlov should know; he has spent the last 15 years tracking and forecasting lasers and optical modules for the telecom and datacom markets.

The tunable laser market is certainly sizeable; over half a million units will be shipped in 2014, says LightCounting. But the market requires care when forecasting. One subtlety is that certain optical component companies - Finisar, JDSU and Oclaro - are vertically integrated and use their own tunable lasers within the optical modules they sell. LightCounting counts these as module sales rather than tunable laser ones.

Optical transceiver market to grow 50 percent by 2017

• The optical transceiver market will grow to US $5.1bn in 2017
• The fierce price declines of 2012 will lessen during the forecast period
• Stronger traffic growth could have a significant positive effect on transceiver market growth

"The price declines in 2012 were brutal but they will not happen again [during the forecast period]"

China and the global PON market

China has become the world's biggest market for passive optical network (PON) technology even though deployments there have barely begun. That is because China, with approximately a quarter of a billion households, dwarfs all other markets. Yet according to market research firm Ovum, only 7% of Chinese homes were connected by year end 2011. 

"In 2012, BOSAs [board-based PON optical sub-assemblies] will represent the majority versus optical transceivers for PON ONTs and ONUs"

60-second interview with .... Sterling Perrin

Heavy Reading has published a report Photonic Integration, Super Channels & the March to Terabit Networks. In this 60-second interview, Sterling Perrin, senior analyst at the market research company, talks about the report's findings and the technology's importance for telecom and datacom.

"PICs will be an important part of an ensemble cast, but will not have the starring role. Some may dismiss PICs for this reason, but that would be a mistake – we still need them."

Huawei's novel Petabit switch

The Chinese equipment maker showcased a prototype optical switch at this year's OFC/NFOEC that can scale to 10 Petabit. 

"Although the numbers [400,000 lasers] appear quite staggering, they point to a need for photonic integration"
