The high-density MPO/MTP fiber optic distribution cabinet is an integrated optical distribution device specifically designed for large data centers, campus core equipment rooms, and communication operator aggregation nodes. Based on a closed cabinet structure, it integrates MPO/MTP pre-terminated modules, adapters, cable management systems, and optional optical splitting components. It enables centralized access, signal splitting, link scheduling, and unified management of MPO/MTP backbone cables, serving as the core hub for the entire optical network link from "backbone aggregation" to "terminal distribution" and adapting to 10G/100G high-bandwidth and large-scale optical connection requirements
