Test Report on Energy-Saving DAC High-Speed Cable
This edited past contribution to INMR by Paul Leufkens of Power Projects Leufkens in the United States along with Prof. Edward Gulski and Rogier Jongen at onsite hv solutions in Switzerland, focused on application of DAC for after-laying testing and diagnostics of all types of. IEC standards for power cable systems up to and above 150 kV rated voltage are manufacturer standards and, according to experts, do not necessarily provide adequate recommendations for testing after-installation. The IEEE Guide for Field Testing of Shielded Power Cable Systems Rated 5 kV and Above with Damped Alternating Current (DAC) Voltage, has been available for the past 7 years [3, 16]. Advanced DAC technology utilizes voltage testing in combination with non-destructive diagnostic methods, such as partial discharge (PD) detection and dissipation factor (tan δ) measurement of the cable system and associated accessories.

Test Report on the New Long-Distance Optical Transceiver
TOKYO - August 12, 2025 - NTT has successfully demonstrated long-haul, high-capacity optical transmission at 160 terabits per second over distances exceeding 1,000 km. In this report, we delve into the pursuit of efficient, high-speed data, and long-range transmission, unveiling the state-of-the-art optical transceivers. Huawei commissioned EANTC to validate functional, interoperability, and performance aspects of the Huawei OptiXtrans DC908 wave division multiplex (WDM) solution with a specific focus on the Storage Area Network (SAN) use case scenarios. Reliable optical transceiver performance keeps your network running smoothly and avoids costly interruptions. For example, flaws in wavelength stability, power output, or temperature tolerance can lead to data loss, latency, or hardware.

Fiber Optic Patch Cord Interchangeability Test
In this blog post, we'll take a deep dive into the key performance tests for fiber optic patch cords — polarity verification, insertion loss and return loss measurement, 3D interferometric endface metrology, and endface inspection — along with the relevant standards, equipment . This Applications Engineering Note (AEN 135) explains and recommends standard measurement methods for characterizing optical fiber system performance. This note also provides background information on system link configurations, test equipment and system component considerations that influence. Equipment cords are an integral part of any network—whether it's a fiber jumper used to make connections between fiber patching areas and switches in the data center or a copper patch cord out in the LAN to connect end devices to the work area outlet. After connectors are added to a cable, testing must include the loss of the fiber in the cable plus the loss of the connectors. Quality of the patch cord has a direct impact on the transmission efficiency and stability of optical signals.
