VPIphotonics and Luceda Photonics collaborate on tools for PIC simulation and layout

VPIphotonics and Luceda Photonics have teamed up to develop a method to automatically export photonic circuit designs from the VPIcomponentMaker Photonic Circuits design software into IPKISS.eda for layout design and mask generation.

The interface was developed at the request of customers, especially those involved in silicon photonics, according to the two companies.

Nokia Bell Labs, T-Labs and Technical University of Munich test drive novel modulation scheme

ECOC 2016 – Nokia Bell Labs, working with Deutsche Telekom T-Labs and the Technical University of Munich, has achieved terabit transmission capacity and unprecedented spectral efficiency in a network field trial using a new modulation technique, called probabilistic constellation shaping.

This research will help telecom operators and enterprises to further optimise the distance and capacity of their optical networks – by dynamically adjusting transmission rates to suit the channel conditions.

Infinera serves up Transport SDN with Xceed Software Suite

Infinera has unveiled the Xceed Software Suite, a portfolio of modular software components that can automate service provisioning in Infinera-based optical transport networks.

The suite comes in two main parts. The Xceed Multi-layer SDN Platform provides software-defined networking-based automation of control plane functions. The Xceed Applications are a set of starter ‘apps’ that enable service providers to immediately start using the new software to activate bandwidth and reconfigure network resources.

First light for Intel’s silicon photonics transceivers

On August 17 at the Intel Developer Forum in San Francisco, Intel announced that its silicon photonics platform is now in volume production and shipping in the form of 100G optical transceivers.

The announcement highlights the maturity of this technology, as demonstrated by the commercial availability of the first products, the company asserts.

Adtran develops tunable subscriber optics for NG-PON2

Optical access vendor Adtran announced the development of what it calls Subscriber Edge Tunable (SET) transceivers for next-generation passive optical networks at its annual analyst event held this week in its Huntsville, Alabama headquarters.

Nokia and Orange Poland set new capacity-distance record

Orange and Nokia have achieved what they claim is a new optical transmission record for 250Gb/s per wavelength, sending a 1.5Tb/s super-channel over a distance of 870km across Orange Poland's existing network infrastructure.

These results represent a 250 per cent increase in capacity per wavelength compared to mainstream 100Gb/s optical systems, using the same amount of spectrum while also gaining a 70 per cent distance improvement over comparable field trials.

Coriant outlines new vision for IP-optical integration

Optical systems supplier Coriant is proposing a new and potentially cost-disruptive network architecture designed to provide better cost-per-bit economics for service provider networks that are increasingly dominated by asymmetric data traffic.

Dubbed Coriant Light IP, the new architecture integrates IP routing with optical transport while virtualising the higher layer network functions.

Microsoft shakes up the data centre interconnect market

OSA Executive Forum 2016 -- The metro market represents the next big opportunity for vendors of data centre interconnect (DCI) equipment, but it seems that not everybody wants new boxes.

One large prospective purchaser of such equipment, Microsoft, says it doesn’t intend to use purpose-built DCI platforms for the sweet spot in its network, namely links of 40km or less.

Infinera generates some buzz: To infinite capacity and beyond

Infinera is planning to shoot straight past the terabit benchmark to reach multi-terabit capacity with its next generation of optical transmission technology. The company has disclosed details of the ‘Infinite Capacity Engine’, an optical subsystem capable of providing up to 2.4Tb/s of capacity in a single package roughly the size of the credit cards in your wallet.

“We are taking optical transport to the next level with the Infinite Capacity Engine. It’s the first multi-terabit optical subsystem,” claimed Pravin Mahajan, director of product and corporate marketing at Infinera.

Nokia claims capacity leap from new silicon and systems

The optical division from Nokia has announced technology and product enhancements that will enable service providers to quadruple the amount of capacity transmitted over an optical fibre.

By doubling the capacity of a single wavelength and simultaneously doubling the number of wavelengths transmitted per fibre, Nokia’s flagship 1830 Photonic Services Switch (PSS) platform will scale to support more than 70Tb/s per fibre, the company claims.
