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.

OpenLight releases 800G DR8 Photonic Integrated Circuit

OpenLight, a start-used based in Mountain View, California, released its first 800G DR8 photonic integrated circuit (PIC) design targeted at datacenter interconnect transceivers.

OpenLight said its on-chip laser integration and high-speed InP-based modulators removes the need for the procurement and attachment of additional lasers into a PIC, offering scalability with high-speed performance and cost at scale to tackle complex designs. The device is built on Tower Semiconductor’s silicon photonics production process (PH18DA) and is a fully validated PIC design with an associated circuit model and available test datasets. The 800G DR8 PIC sample kits are now available.

OpenLight has fabricated and tested these wafers using the world's first open silicon photonics foundry platform with integrated lasers offered by Tower Semiconductor. 

“As the number of users and devices per user continue to increase, the demand for bandwidth and higher data rates will only grow multifold. We are seeing an uptake in the adoption of silicon photonics and believe our first-of-its-kind 800G DR8 PIC design and available tested samples will help customers quickly design optical transceiver modules and enable faster time to market for emerging datacom needs,” said Dr. Thomas Mader, Chief Operating Officer at OpenLight. "Together with Tower, we are able to consistently offer scalable design solutions and support the industry’s move to 800G and beyond for datacenters with integrated lasers."

“Our partnership with OpenLight continues to add new, silicon-proven IP to Tower’s existing open foundry offering enabling customers to accelerate development of next generation silicon photonics products with fully integrated lasers,” said Dr. Marco Racanelli, Senior Vice President and General Manager of Tower Semiconductor’s Analog Business Unit. “The process technology and PDK are available to Tower customers along with regularly scheduled shuttle runs while higher order IP such as the 800G reference design announced here, is available through our partner OpenLight"
