Level 3 introduces encrypted wavelength service

Level 3 Communications has launched an encrypted wavelength service to help global enterprises secure their optical connections from unlawful interception and fiber tapping.

The encrypted waves service, which uses AES 256-bit encryption, provides enterprises with a single network view. Customers maintain complete control over their encryption keys via the MyLevel3 portal and a Level 3-provided key management system.

Unlike with cloud-based encryption schemes, Level 3 says its optical layer service does not incur a performance penalty, ultra-low latency is preserved and there is no throughput degredation. In addition, customers do not need to invest in in additional encryption equipment to leverage encrypted waves between key customer locations.

"Every element of a critical network today has to be hardened against security attacks. Level 3 encrypted waves offer enterprises peace of mind by addressing security threats such as unlawful interception and fiber tapping, without sacrificing network performance. Unlike other optical encryption solutions on the market today, our solution provides greater direct customer control with built-in encryption key management through our portal. This is just one example of how Level 3 continues to deliver a truly customer-defined adaptive networking experience," stated Paul Savill, SVP of Core Products for Level 3.

Oclaro show coherent transceiver for 400G and 600G wavelengths

Oclaro is getting ready to sample its first photonic integrated coherent transmitters (ICTs) and intradyne coherent receiver (ICRs) for 400G and 600G wavelengths. The devices, which could be configured for multiple data rates, are designed for high-performance coherent optical systems for applications ranging from data center interconnects (DCIs) to ultra-long haul transmission.

Oclaro 64Gbaud ICT combines an ultra narrow line width laser with a high-bandwidth dual QPSK Mach Zehnder Modulator to support flexible baud rates up to 64Gbaud and 64-QAM modulation. The device has an integrated semiconductor optical amplifiers (SOAs), a tunable filter and a variable optical attenuator (VOA). It also includes a local oscillator (LO) feed with +12dBm output power for optimal receiver performance.

The photonic intregration uses indium phosphide technology.

Oclaro is showcasing these two new products at this week's ECOC Exhibition in Sweden. Sampling is expected in Q4 2017.

"With our ICR and ICT product offerings, customers will be able to design high-performance coherent systems that are both flexible in the bandwidth offered per port and cost competitive by maximizing the data that can be carried on a single wavelength," said Beck Mason, President, Integrated Photonics Business Unit at Oclaro.

NTT Group seeks growth through diversification – part 1

The NTT Group ranks among the top carriers worldwide by nearly any metric, whether by revenue, subscribers, traffic, corporate debt, overseas investments or industry influence.  We know the acronym stands for Nippon Telegraph and Telephone Corporation, the incumbent telecom provider of Japan that still owns most of the last mile infrastructure of the company and is a leading innovator in optical and mobile networking technologies.  Recently, however, company executives, spelled out the acronym as follows:

Next value partner for
Transformation of business models and lifestyle by
Trusted Solutions of global, secure, end-to-end and full-line ICT services.

There are many key words in this new rendition of the company name but chief among them is “partner”. In its corporate strategy presentation, NTT executives now routinely emphasize the company’s willingness and ambition to seek partners both in Japan and abroad for the many opportunities it sees with artificial intelligence (AI), Big Data, telematics, IoT, entertainment, and even the management of modern sport stadiums.


NTT is certainly a big group. As of March 2017, it had 944 subsidiary companies and 274,850 employees.
