Télécommunications et réseaux 5G
Systèmes d'alimentation DC, énergie de site et liaisons optiques pour réseaux mobiles et fixes.
Aperçu
Telecom environments vary from macro sites to edge nodes, each with different load, space, ambient, and service conditions. Selection begins by confirming the existing network, expansion plan, incoming supply, DC bus, backup target, and remote-operations requirements.
The power chain commonly includes -48 V DC systems, rectifiers, controllers, distribution, telecom batteries, and indoor or outdoor power cabinets. Weak-grid and off-grid sites may also require coordinated solar, generator, and storage inputs, with interfaces and expansion capability verified in advance.
Cooling for outdoor cabinets and compact equipment rooms must reflect ambient temperature, dust, humidity, enclosure protection, and installation space. Capacity is calculated from the actual cabinet heat load rather than a generic site label.
SFP optical modules, KVM, and monitoring interfaces are checked for speed, reach, fiber type, protocol, and equipment compatibility. HEFENGQI organizes the bill of materials around exact models and source documents for procurement, delivery, and maintenance.
