Anritsu 400G Testing, Support for IOWN Open APN at OFC

Anritsu Corporation, NTT to jointly participate in the “OFCnet” state-of-the-art network demonstration environment during the ongoing Optical Fiber Communication Conference and Exhibition 2024 (OFC2024).Anritsu at OFC 400G Testing, Supports IOWN Open APN the volt post

Here Anritsu plans to showcase 400G Testing that supports IOWN Open APN. To realize a Datacenter Exchange (DCX) that connects remotely distributed Datacenters while featuring ultra-high capacity, ultra-low latency, and ultra-low power consumption, the IOWN Global Forum has proposed the Open All-Photonic Network (Open APN) as a new network infrastructure aka IOWN Open APN.

IOWN Open APN believes the vigorous adoption of Generative AI, cloud services and rapid advances in DX (Digital Transformation) are driving the growth of interconnection bandwidth between datacenters.


The IOWN Networking Hub(IOWN Open APN) (Booth 912) With Anritsu, an interconnected booth utilizing OFCnet, will showcase:

An example Datacenter Exchange (DCX) based on the IOWN Open APN in a multi-vendor configuration.

400G optical transceivers compliant with the OpenZR+ MSA will be mounted on data center switches, being interconnected through an OpenROADM network constructed in an adjacent booth, in accordance with OpenROADM MSA and OpenLab@ University of Texas at Dallas (UTD).

Anritsu will provide two interconnected compact and lightweight handheld measuring instruments, MT1040A. It simultaneously transmits and receive high-bandwidth 400-Gbps traffic, thereby demonstrating the end-to-end performance of the multi-vendor network.

The MT1040A flexibly supports standard protocols such as 400G Ethernet, OpenZR+, OpenROADM, and more. It provides real-time measurements of the physical layer (Layer 1) Pre/Post FEC BER, as well as Ethernet (Layer 2) latency and throughput.

Through this collaboration, Anritsu will contribute to forums such as the IOWN Global Forum, Open ROADM, and OpenZR+, with the realization of a data center exchange (DCX) based on the IOWN Open APN architecture. In addition, the company aims to contribute to the construction of automated systems used for orchestration that integrate higher-level network management.

MT1040A Network Master Pro / MU104014B 400G (QSFP-DD) multi-rate module

MT1040A is a B5 size 400G handheld tester with excellent expandability and operability. It is a touch panel-operated field measurement instrument equipped with a 9-inch screen that is small enough to carry with a single hand. It supports a range of interfaces from 10M up to 400G.

MU104014B is the test module and has the following futures to test 400ZR/ZR+

  • Powerful hardware for easy handling 400ZR/ZR+ transceivers
  • Flexible Settings for All Network Environments
    • Grid, Wavelength, Tx Power setting
    • Coherent monitoring (OSNR, SOP, CD, etc.) via OIF CMIS
    • Media-side FEC monitoring (PreFEC BER) via OIF CMIS
    • 1x 400G, 4x 100G, 2x 100G, 1x 100G client signal
    • Flexible Layer-2 to Layer-4 configuration
  • History Function Monitoring Live Network
    • Auto-save all of results at a minimum of 1 second
    • CSV output for detailed analysis and comparison
