Materials and Design for High Performance
The dome body is made of high-strength PP or reinforced ABS that is used in industry. This makes it strong, resistant to UV rays, and resistant to corrosion. The closure works well even when the temperature is very low or very high, from -40°C to +65°C. It is also IP68-rated, which means it is very good at keeping out water and dust.
International standards IEC 61753, YD/T 814.1, and RoHS are used to make Hiphotonics closures. To make sure that each closure will work well in the field for a long time, it goes through demanding quality and sealing performance tests, such as air pressure sealing tests and thermal cycling validation.

High production capacity and the ability to customize
Hiphotonics has eight innovative production lines that make fiber optic closures. They make more than 15,000 pieces a month. Because we can change how much we make, we can get things done quickly—usually in 5 to 7 business days for basic models. We also offer custom design services based on what the customer needs, such as:
Making your own labels and logos
Choosing special materials, like plastics that don't catch fire or stay cold
Special port setups and parts that are color-coded
Proven Quality and Global Deployment
Hiphotonics has been making things for more than 21 years and has a competent technical staff. Their closures are used in national broadband projects, 5G backhaul, data center access networks, and rural FTTH rollouts in more than 80 countries. Telecom companies, system integrators, and project contractors all around the world trust our products.
Hiphotonics's dome-type closures give you the reliability, capacity, and performance you need whether you're establishing a high-density FTTH network, upgrading existing optical access infrastructure, or designing a fiber backbone that can grow.
