High-Voltage Cable Distributed Temperature Monitoring System
The distributed online temperature-monitoring system for high-voltage power cables is designed to prevent fires caused by overheating at cable joints. It accurately and promptly transmits temperatures along the cable to the central control room. If a measured temperature exceeds the preset alarm threshold, the system issues an alarm for timely action. Microwave and electromagnetic interference in high-voltage equipment can make conventional temperature measurements difficult or unreliable. Distributed fiber-optic temperature sensing offers distinctive advantages: optical fiber carries both sensing and transmission signals, overcoming strong electromagnetic interference in power systems; a single fiber senses and transmits temperature information along its length; advanced OTDR technology and the temperature sensitivity of Raman scattering identify temperature changes at different positions. This provides truly distributed measurement for long-distance temperature measurement, real-time online monitoring and fire alarms. The system uses a special temperature-sensing fiber-optic cable as the detector. It is electrically passive, intrinsically explosion-proof, lightning-resistant, corrosion-resistant and immune to electromagnetic interference, enabling real-time monitoring of internal temperatures in large power-cable installations. Military-grade lasers, telecommunications-grade photodetectors and fiber filters improve reliability. Closed-loop control prevents accuracy degradation caused by ambient-temperature changes and component temperature drift. A modular design simplifies maintenance, and stringent product testing supports stable, reliable long-term operation in harsh environments.

Tera2060 six-channel 1.25~12.5G electrical bit-error-rate tester
Communications & Energy
Terawan
Data Rate [RF performance table]: 1.25~12.5 Gb/s Output amplitude [RF performance table]: 200~800 mV Output jitter (P-P) [RF performance table; PRBS31]: typical:5 Ps
The Tera2060 simultaneously provides six electrical pattern-generation/error-detection channels at 1.25G/2.5G/5G/6G/8G/10G/12.5G. The first four RF ports share a rate selected from 5G/6G/8G/10G/12.5Gb/s; the second two share a rate from 1.25G/2.5G/5G/6G/8G/10G/12.5G. The two groups can be adjusted independently. It mainly serves 10GE/40G module/AOC development with 6 precision channels over 1.25G~12.5G and tests SFP modules/AOC and HDMI1.4, HDMI2.0, HDMI2.1, or USB3.0 cables.
