Coherent Corp. announced its latest advancement in fiber network diagnostics with the introduction of a high-performance embedded Optical Time Domain Reflectometer (eOTDR) in a QSFP package. This new device offers an industry-leading 30 dB dynamic range, enabling precise and repeatable OTDR traces for spans up to 150 km.
With rising bandwidth demands, real-time fiber-plant health monitoring is critical for data center interconnects and telecom networks. The eOTDR provides precise fiber span measurements, including absolute loss, reflection values, and industry-standard SOR span traces, which can be combined with optical channel monitors for unmatched visibility.
Dr. Sanjai Parthasarthi, Chief Marketing Officer at Coherent, highlighted the challenge of integrating complex electrical processing and high-performance optics into a compact pluggable module. This plug-and-play solution enhances network diagnostics and supports a scalable, 'pay-as-you-grow' deployment model for operators.
