IDM MK

I. Overview

The IDM MK-MSTP Intrinsically Safe Optical-Electrical Integrated Transmission Equipment is a brand-new mining information transmission device that provides 100/1000Mbps Fast Ethernet and intrinsically safe voice interfaces. It is an essential explosion-proof communication product for establishing integrated service access and transmission underground. This product supports remote management via the network; it integrates MSTP transmission and PCM multi-service access functions, utilizing SDH optical fiber ring network protection to provide more reliable communication protection.

The IDM MK-MSTP can directly connect to underground intrinsically safe telephones, intrinsically safe cameras, intrinsically safe broadcasting terminals, and other endpoints.
