NTT to test Open All Photonics Network wavelength interconnects

NTT, in collaboration with Ciena, Fujitsu, and NEC Corporation (NEC), will conduct Open All Photonics Network (APN) proof-of-concept (PoC) trial of on-demand wavelength technologies.

NTT said the work is based on the Open All Photonics Network (APN) Functional Architecture document published by the IOWN GF earlier this year.

The network nodes defined in the Open APN Functional Architecture can be constructed from the Open ROADM MSA’s standard components, which are available from global optical product vendors such as Ciena, Fujitsu, and NEC. To prove the viability and operability of Open APN, NTT will conduct a PoC jointly with Ciena, Fujitsu, NEC, and other companies in the fourth quarter of fiscal 2022. The PoC will validate wavelength connection creation/deletion functions and evaluate the performance of optical communications in terms of throughput, delay, and jitter.

The PoC should prove that Open APN is implementable and operable with products already available in the global market and encourage many organizations in the world to build and implement Open APN.

While conventional ROADM products are designed to create optical connections between telecommunication carriers’ sites, an Open APN creates connections between all endpoints, including customer sites. This difference leads to the need for new functions as listed below:

  • A function for automatically designing and provisioning wavelength connections that satisfy service requirements by cooperation and coordination of terminals deployed in user sites and carrier equipment, and functions for selecting the best transmission mode, etc.
  • A function for configuring and managing optical wavelength end points of terminals deployed in user sites and a function for passing and blocking optical signals in carrier equipment based on the authentication status of each terminal
  • A function for adapting different types of optical fibers to be connected in the same optical wavelength

NTT has developed the above functions and started a field test in the Tokyo metropolitan area. The test should validate their operability under various conditions, such as fiber length and loss levels in a real environment. As the test will also utilize the outcome from Open ROADM MSA and Telecom Infra Project Open Optical & Packet Transport6, it should demonstrate how the results from the three organizations can be combined to build open and disaggregated infrastructures.

NTT develops graphene as a high-speed photodetector material

NTT and Japan's National Institute for Materials Science (NIMS) achieved the world's fastest zero-bias operation1(220 GHz) of a graphene photodetector (PD). 

The research clarifies the optical-to-electrical (O-E) conversion process in graphene for the first time. Graphene has high sensitivity and high-speed electrical response to a wide range of electromagnetic waves, from terahertz (THz) to ultraviolet (UV). Thus, it is a promising photodetection material for enabling high-speed O-E conversion at wavelength ranges where existing semiconductor devices cannot operate. However, until now, the demonstrated zero-bias operating speed has been limited to 70 GHz due to conventional device structure and measurement equipment. For this reason, the challenge for graphene PDs is to demonstrate 200-GHz operation speeds and clarify graphene's inherent properties, such the process of optical-to-electrical conversion.

In this study, NTT and NIMS demonstrated high-speed operation with a 3dB bandwidth of 220 GHz by removing the current delay caused by the device structure by using zinc oxide (ZnO) thin film as the gate material and by using on-chip THz spectroscopy technology to read out the current at high speed. The research also found a trade-off between operating speed and sensitivity by comparing the characteristics of PDs fabricated with graphene of different qualities. The findings will enable graphene PDs to be optimized according to their intended use, such as in optical sensors prioritizing sensitivity or O-E signal converters prioritizing speed. 

The research was published online in the British scientific journal Nature Photonics on August 25th, 2022.

Farice plans fiber route linking Iceland, Ireland and Japan

Farice reached a sales agrement with Far North Digital (FND) for fiber connectivity between Japan and Iceland via Farice’s new IRIS submarine cable and FND’s planned Arctic cable.

Construction is currently underway for Farice's IRIS Subsea Telecoms Cable System from Iceland to Galway, Ireland. The system is planned for service early 2023.

The FND fiber cable will be the first Arctic route connecting Asia with Europe via the Northwest Passage, greatly reducing the optical distance between Asia and Europe, thus minimizing latency.  FND is aiming for commercial launch by the end of 2026.

Farice and FND have agreed to develop a connectivity exchange at their shared landing site in Galway, Ireland.  Through the exchange, customers will be able to buy direct connectivity between Japan and Iceland, linking the third largest economy in the world and Iceland, which has 100% green and sustainable electricity.

“We are very excited about the development of the new Arctic fibre cable that will bring the continents of Asia, Northern America and Europe closer together.  The landing of the cable in Galway next to our IRIS cable will drive the development of a new submarine network exchange, connecting Iceland to Asia, North America and Northern Scandinavia”, says Thorvardur Sveinsson, CEO of Farice.

“Farice is a terrific partner, and Iceland has the renewable resources to make the Internet greener”, says Guy Houser, FND’s Chief Technical Officer.  “Our combined system offers faster and more secure connectivity for the world and the North.  It is critical infrastructure in the information age.”

IRIS cable to link Iceland to Ireland with up to 108 Tbps

IRIS, a new six-fiber pair undersea cable system, will connect Iceland and Ireland with up to 108 Tbps of system capacity.

Farice, the international connectivity provider fully owned by the Icelandic Government, has selected Subcom as the primary contractor.

Currently, there are two other submarine cable systems that connect Iceland to Europe – FARICE-1 (2003) and DANICE (2009). 

IRIS will be approximately 1,700 km in length and connect south west of Iceland to Ballyloughane Strand in Galway, Ireland. Farice has already finalized the DTS and marine survey work on Ireland’s continental shelf and will complete the remaining survey works to Iceland in 2021. Manufacture of the cable and equipment will take place at SubCom’s manufacturing headquarters in Newington, NH, USA during 2021 and early 2022, with main lay installation operations scheduled for summer 2022. The system is expected to be ready for service by the end of 2022.

Farice opted to land the IRIS cable in Ireland, a nexus of trans-Atlantic connections and a center of European operations for many international businesses. IRIS will directly connect to a new high-speed undersea cable system that will enable more diverse, secure, high-speed connectivity between Iceland and mainland Europe.

Mitsubishi Electric develops optical receiver for space laser

Mitsubishi Electric Corporation has developed an optical receiver for use in laser communication terminals (LCTs). The prototype combines laser beams with a function to detect the direction of received beams in the 1.5-μm band, a general-purpose band used for terrestrial optical fiber communications and other applications. 

Mitsubishi Electric said its optical receiver integrates functions to detect both four phase changes of laser light and beam direction. The result is a downsized optical receiver that enables space optical communication with 10 times the speed, capacity and distance of radio-wave communication. Since the wavelength is much shorter, smaller antennas can be used in compact communication units.

A newly developed optical circuit for coherent space optical communication detects four phase changes (0, 90, 180, and 270 degrees) in contrast to conventional two-phase (0 and 180 degrees) detection. As a result, communication capacity and speed are double those of two-phase optical communication schemes in the same bandwidth and some 10 times those of radio-wave communication systems.
