Coherent unveils compact fiber diagnostic tool

SAXONBURG, PA - Coherent Corp. (NYSE: COHR), a $10.57 billion market cap photonics company with robust revenue growth of 14.6% over the last twelve months, introduced a new embedded Optical Time Domain Reflectometer (eOTDR) designed for fiber network diagnostics within a compact QSFP module. This latest innovation, boasting a 30 dB dynamic range, facilitates precise fiber span measurements for up to 150 km, catering to the growing need for real-time monitoring in data centers and telecom networks.

The eOTDR’s advanced capabilities include measuring absolute loss, reflection values, and providing industry-standard SOR span traces. When used with optical channel monitors, it offers comprehensive insights into channel and system performance, allowing for real-time optimization and predictive maintenance through AI and machine learning integration.

Coherent’s new QSFP eOTDR is part of a modular family that features a CMIS-based interface for easy integration into existing routers. This plug-and-play approach aims to enhance network diagnostics while reducing infrastructure disruptions. The company’s strong financial position, evidenced by a healthy current ratio of 2.67, supports its continued innovation in the fiber optics space. According to InvestingPro data, Coherent maintains substantial liquid assets exceeding short-term obligations, positioning it well for ongoing R&D investments.

Dr. Sanjai Parthasarthi, Chief Marketing Officer at Coherent, highlighted the challenge of integrating complex electrical processing and high-performance optics into such a compact module. He emphasized the flexibility and performance benefits that this innovation brings to fiber diagnostics.

This development is a continuation of Coherent’s leadership in embedded OTDR technology, addressing the needs of ultra-high-capacity fiber networks where immediate visibility and proactive maintenance are essential. Coherent also provides complementary fiber monitoring tools, including optical channel monitors, to ensure a comprehensive view of fiber health, maximize uptime, and support network performance optimization.

The product will be showcased at the upcoming OFC 2025 event in San Francisco from April 1-3. Coherent’s commitment to innovation in the photonics industry is evident in its extensive range of solutions for various applications across industrial, communications, electronics, and instrumentation markets.
