The Rhi-Node 1000 chamber (MHL-003) is deployed in underground telecommunications and other utility infrastructure, complementary to blown fibre cable applications. It is modular to achieve flat-stack packaging. The chamber is cylindrical to maximise strength and internal space utilisation. It features a split entry design, to accommodate drop-in installation over existing ducts of various diameters. All its components are manufactured in a quality assured factory, certified to ISO 9001.
The lid and frame of the chamber incorporate a mechanical locking mechanism and is available with a feature enabling unique identification and automated GPS positioning of its location. Brackets are provided for cable slack management, and adding additional cables during the chamber lifespan.
An electronic locking solution and an IoT environmental sensor are available optionally, to remotely manage access to the chamber and to monitor the environment inside it and receive alarms when pre-determined levels of vibration/impact and light are exceeded.
