Telecommunications and Communication Technologies Testing Services
In the borderless nature of the digital world, never losing connection is the key to success. However, entering global markets in the telecommunications and IT sector is not just a matter of innovation, but also a process of full compliance with complex laws and regulations set by different countries and service providers. At GTL (Global Technology Laboratory), we simplify the entire process for you, ensuring your communication technologies are registered to world standards and providing seamless access to new markets.
Strategic Guidance from Design to Market Success
In this innovation-driven sector, achieving market success depends on product design meeting the ever-changing expectations of the end-user. GTL is not just a technical testing center, but also a strategic solution partner:
- Usability and Design Review: We review designs, conduct tests on specific target groups, and provide valuable insights into the usability of your products.
- Certification and Regulatory Management: When your products are ready for market launch, we certify your equipment according to relevant national and international standards and manage communication with relevant authorities on your behalf.
- Electrical Safety: We help you maintain your competitive advantage by ensuring the highest level of safety for electronic components and devices.
Our Technical Testing Capabilities and Telcordia Standards
We apply the strictest international protocols to ensure that telecommunications infrastructure equipment can provide uninterrupted service in challenging environmental conditions. The main test categories carried out in our laboratories and detailed in the attached tables are as follows:
- Fiber Optic Component and Connector Testing (Telcordia GR-1221, GR-1209, GR-326-CORE): For passive components and connectors, the backbone of fiber optic networks, we apply thermal shock, high-temperature storage, humid heat aging, and cyclic humidity resistance tests. We also certify the continuity of optical transmission with dust tests and adhesive durability analyses for connectors.
- Optioelectronic Systems (Telcordia GR-468-CORE): For sensitive systems such as lasers and photodetectors, we test system reliability in extreme scenarios with accelerated aging (2,000 - 5,000 hours), thermal shock, and humid heat tests.
- Network Switching and External Interface Devices (Telcordia GR-63, GR-49-CORE): Within the framework of NEBS requirements, we perform low and high temperature exposure, operating altitude (up to 4,000 meters above sea level), and relative humidity exposure tests for network switching systems. For external network interface devices, we conduct outdoor environmental durability analyses such as mold stress and humid temperature cycling.
- Enclosures and Field Equipment (Telcordia GR-487-CORE): For enclosures used in open areas, we ensure that the equipment remains completely isolated and protected from the outside world through high ambient temperature simulations, thermal shock, and corrosion resistance tests.
