- NR/L2/TEL/31200Design of High-Capacity Fibre Cable Systems
What the standard is for: principles for building, extending or maintaining NR's high-capacity (ribbon) fibre network
24 clauses mapped
- NR/L2/TEL/30160Specification for Loose-Tube Optical Fibre Network Design
What the standard is for: the principles behind adding to or changing NR's existing loose-tube fibre network so capacity is protected. Issue 5 note: High Count Fibre Cable (HCFC) is now the default for new trunk cable under NR/L1/TEL/30102 — new trunk fibre is designed to NR/L2/TEL/31200; 30160 is for upkeep of, and designs interfacing with, existing loose-tube assets
50 clauses mapped
- NR/L2/TEL/30179Design of Fibre Distribution Systems and Fibre End-User Connections
What the standard is for: how end users are connected to NR's fibre without harming trunk capacity. Issue 2 note: commercial demand is now long-haul fibre, so new FIPs and FATs are not expected to be deployed — 30179 is for upkeep of, and designs interfacing with, existing FIP/FAT assets (e.g. the TPI area), and most of its design rules are now worded as guidance (should) rather than mandatory (shall)
