The MPX01-SM-C type double-sided digital distribution cabinet is suitable for the wiring and connection of digital signals from digital terminal devices or program-controlled switches with a transmission rate of less than 2-155Mbit/s. It has functions such as circuit scheduling, switching, and testing, making maintenance convenient and allowing for flexible circuit rewiring and service changes.

Features

The rack structure is diverse, including open type, fully enclosed type, and strip frame type.
Modular combination with flexible configuration. Easy to install, the surface of the all-aluminum alloy rack is treated with electrostatic spraying, which has strong adhesion, and is made of stainless steel material, giving it an attractive appearance.
Uses surface gold-plated coaxial connectors with low contact resistance and reliable connections.
There is ample wiring and routing space inside the rack. Wiring, adjustment, and monitoring are extremely convenient.
The unit can be flipped down 90°, facilitating maintenance operations.
