HYWICOM Launches World's Most Powerful Portable 800G OTN Tester
Press Release: On May 25, 2025, Shanghai, China – HYWICOM, a global leader in optical communication test solutions, today announced the world’s most powerful portable multi-port 800G optical transport tester, the PIANO OTN Edition, following last month’s release of its multi-port 1.6Tbps high-speed Ethernet test platform based on 224G SerDes technology. This latest innovation addresses the growing testing demands for AI and optical network upgrades, field testing, and maintenance. Key features include:
Industry’s Only 800G OTL4.1/FOIC1.1
Dual Protocols - OTN & Ethernet
Highest Port Density
Largest Traffic Testing Bandwidth
Longest Battery Operation Time
Most Comprehensive Coherent Testing
The PIANO OTN Edition will be showcased at Booth A02 during the 25th OptiNet China Conference in Beijing (June 4–5). Industry partners are invited to visit and explore the product firsthand.
PIANO OTN Edition
Since China’s national backbone network began its shift from 100G/200G generation to 400G generation in 2024, all three major network operators have entered a rapid deployment phase for 400G networks. Meanwhile, 800G OTN is also advancing vigorously. However, through close collaboration with the China Academy of Information and Communications Technology (CAICT), network operators, and equipment vendors, HYWICOM has identified persistent challenges in field testing for 400G+ networks, including limitations in test bandwidth capacity, protocol completeness, operational intelligence, and cost efficiency.
Key Pain Points in Current Field Testing Instruments
For example, operators and vendors require simultaneous use of 400G/100G and 10G ports. However, existing portable testers have long suffered from the inability to use 400G/100G and 10G ports concurrently.
Current portable testers fail to support main-stream optical interfaces at the same time, such as QSFP-DD, OSFP, OSFP-RHS, CFP2, and SFP. They also cannot handle multiple rates simultaneously, such as 800G, 400G, 200G, 100G, 10G, forcing users to purchase multiple testers for different rates and form factors — drastically increasing procurement, operational, and testing costs.
Compared to lab-grade testers used by R&D, portable field testers often omit critical Ethernet and OTN protocols and test functions, such as multi-stage multiplexing for OTN services and test automation.
Short battery life (e.g., 30 minutes for 400G tests), small displays with poor touch responsiveness and low brightness, and other issues have significantly lowered outdoor usability of current portable testers.
Some testers’ software design logic conflicts with local engineers’ workflows, requiring frequent window-switching and lacking Chinese language support. Users also report sluggish performance, severely reducing efficiency during maintenance.
Security and stability are critical in telecom networks. Some testers, due to operating system issues (e.g., the global “Blue Screen of Death, BSOD” incident last year), suffer from frequent crashes and instability during long-term testing – a major flaw for critical field deployments. As a result, European and domestic users now explicitly require Linux-based systems.
HYWICOM’s PIANO OTN Edition — Addressing User Pain Points
To tackle these challenges, HYWICOM developed the PIANO OTN Edition, featuring the following breakthroughs:
World’s First 800G OTN Test Solution
The PIANO OTN Edition pioneers support for 800G OTN protocol analysis and testing via 8x OTL4.1 and 8x FOIC1.1 interfaces at 112G rate (ITU-T G.709 standard). This provides robust support for 800G OTN validation, field trials, and ecosystem collaboration.
Rich and Flexible Test Interface Configuration
Featuring an innovative modular dual-slot architecture and diverse module options, PIANO supports up to 8 test ports. Single slot alone can accommodate dual 800G/400G QSFP-DD ports, while the second slot expands compatibility with OSFP, OSFP-RHS, CFP2 and SFP-DD.
1.6Tbps Traffic Testing Bandwidth
With a powerful 1.6Tbps traffic generation and monitoring processor, PIANO enables simultaneous and independent operation of two 800G or four 400G ports. One tester covers all OTN, DCI, and data center field test scenarios.
Dual Protocol Support — Ethernet & OTN
Inheriting the comprehensive protocol analysis capabilities of HYWICOM’s TANGO series lab instruments, PIANO supports 800GE-1GE Ethernet protocols and 800G-10G OTN protocols (FlexO, OTU4, OTU2, etc.), including client mapping and multi-stage multiplexing. It enables monitoring/modifying of OTN overhead fields, protection switching time (SDT) measurement, high-precision latency testing, and RFC 2544 benchmarking.
Full Coherent Optical Module Coverage
PIANO supports the industry’s most comprehensive coherent transceiver testing, including 800ZR/ZR+, 400ZR/ZR+, and 100ZR/ZR+ standards, along with QSFP-DD, OSFP, and CFP2-DCO form factors. It also provides complete C-CMIS compliance tests. Therefore, PIANO addresses the test needs of both optical transport and emerging satellite optical communications.
Intuitive Software Design & Multi-Language Support
PIANO features a super user-friendly GUI, simplifying workflow creation and test configuration. The GUI interface supports seamless multi-language operation, e.g. English or Chinese.
Secure and Stable Linux OS
PIANO runs on a Linux-based proprietary OS, ensuring stable operation during extended testing. Its secure architecture eliminates vulnerabilities, safeguarding telecom network security and stability.
Multi-User Sharing & Flexible Operation
PIANO supports touchscreen, WEB UI, VNC, and API access. Each port operates independently, enabling multi-user concurrent testing to maximize resource utilization.
Simplified Field Testing
A 11.6-inch Full-HD (1920 x 1080 pixels) touchscreen with 1,000-nit brightness ensures clear visibility outdoors. Compact and portable, it supports convenient airplane/high-speed rail travel. Automated features like timed testing, report generation, screenshot capture, and WIFI remote control via smartphone simplify complex field workflows.
Dual High-Capacity Batteries & Lower-Power Design
The PIANO’s 95Wh dual batteries together with its advanced low-power design provide the longest battery operation time in the industry. Therefore, it eliminates users' power concerns for field testing. For example, it can provide up to 3 hours of uninterrupted 100G dual-port testing without power.
Conclusion
The launch of HYWICOM’s PIANO OTN Edition marks a significant leap in flexible, autonomous, and sustainable test solutions for 800G/400G OTN networks, DCI interconnects, and satellite optical communications. HYWICOM will continue collaborating with industry partners to drive technical innovation and deliver cutting-edge high-speed connectivity solutions.
