RMT Ltd. has successfully completed its Complex Qualification Program 2024, confirming the reliability and compliance of its thermoelectric coolers (TECs) with industry-leading standards. This program rigorously assesses TEC performance against the requirements of Telcordia GR-468-CORE and RMT’s own specifications (TU 27.90.11-001-68694362-2020). In RMT’s Moscow testing laboratory, over 1000 TECs from 9 different types underwent comprehensive mechanical, environmental and electrical tests, including those outlined in MIL-STD-883. The results demonstrate that RMT TECs consistently meet the demanding criteria of both Telcordia GR-468-CORE and TU 27.90.11-001-68694362-2020, ensuring their reliability and suitability for critical applications.
