- Product Introduction
Telecom Manhole Chamber For Underground Fiber Optic Cable Installation
The GL46 SMC Plastic Assemble Inspection Manhole is an engineered infrastructure solution specifically designed for urban subterranean utility networks. Integrating optical fiber distribution, splicing protection, and intelligent monitoring capabilities, the system supports FTTH deployments and multi-operator co-construction scenarios.
It employs a modular tray architecture enabling centralized access for 24–96-core optical cables, with scalable chamber capacity up to 576 cores to accommodate 5G fronthaul, midhaul, and backhaul requirements. Constructed from aviation-grade perfluoroethylenepropylene (F46) composite material, the system achieves -200°C to +200°C operational temperature resistance and UL94 V-0 flame retardancy, demonstrating threefold superior corrosion resistance compared to conventional PVC. Certified for IP65/IP68 dual sealing ratings and secondary press-cabling integrity, the system maintains zero leakage under 2,000N axial tensile force while operating in extreme conditions ranging from -40°C permafrost to +75°C surface environments. Embedded with a distributed optical fiber strain monitoring system (±0.1με precision) and AI-driven fault diagnostics, it enables real-time deformation detection and predictive maintenance alerts for geological subsidence or human interference, reducing unplanned downtime by 30%.
