Cables Procurement Plan & Structured Cabling Architecture — Shenzhou Cables
A practical, standards‑aligned blueprint for enterprise campuses, office towers, and data halls
Executive Overview
This document defines a complete procurement plan and a reference structured cabling architecture covering fiber and copper systems. It follows TIA‑568 and ISO/IEC 11801 principles, with a hierarchical topology from the Entrance Facility (EF) to the Main Distribution (MDF) and Intermediate Distribution (IDF) rooms, down to Work Areas (WA). The plan emphasizes standards compliance, lifecycle cost reduction, and ease of expansion.
Figure 1. Structured cabling topology from EF → MDF → IDF → Work Areas (TIA‑568).
• Backbone: single‑mode (G.652.D/G.657.A1) for campus/vertical risers; OM4 for short‑reach interconnects
• Horizontal: Cat6A copper to outlets; optional fiber to desk for special workloads
• Demarcation: ODF at EF/MDF; IDF per floor/zone; patch panels and cable managers in all rooms
• Fiber: SM G.652.D/G.657.A1 for long runs; OM4 MM for high‑density short‑reach; connectors SC/APC (PON) or LC/UPC (enterprise)
• Copper: Cat6A U/FTP or F/UTP; channel up to 100 m; PoE++ readiness; permanent link certification per TIA
• Pathways: ladder racks, trays, raceways; separation of power and data; bend‑radius control

Figure 3. Cat6A copper cable — illustrative cross‑section.
• EF/MDF: ODFs, copper patch panels, grounding; environmental control and access security
• IDF: per‑floor distribution; fiber/copper termination; cable managers; labeling and documentation
• WA: TO (telecom outlets) with Cat6A; optional fiber outlets for labs or media suites
Figure 4. Rack front with fiber ODF and Cat6A patch panel (illustrative).
• Backbone EF→MDF→IDFs via risers; redundant diverse routes where feasible
• Horizontal IDF→WAs via trays/raised floor; consolidation points where required
• Labeling: room‑rack‑U‑port conventions; QR code mapping to drawings

Fiber: OTDR bi‑directional at 1310/1550 nm; OLTS IL/ORL; endface inspection. Copper: DSX‑class certification for Cat6A; channel and permanent link. Deliverables: test reports, as‑built drawings (CAD/GIS), and warranty letters.
