Checklists and Documentation

General installation guidelines and quality checklist items that can be used to help minimize plant damage and maximize performance and reliability of the inside building network include the following items.

1. Quality Check on Materials – The sources and suppliers of all cable, connector, closure box and hardware components in the network shall be documented and retained as part of the network acceptance certification. The inspection of all incoming materials and the use of correctly sized and matched tools for cable work (fiber and copper pairs) shall be part of quality assurance procedures for any construction and installation project.

2. Check Engineering Drawings – Network schematics and engineering drawings shall be available and include the list of dwelling units, rooms, layouts and end-to-end cable route with notations of any ceiling /raised floor type construction. The testing protocols and procedures used for cable inspection and final acceptance of network shall be documented.

3. Proper Tool Selection and Use – The correct tools need to be used to obtain a good metallurgical bond for electrical connections or low loss optical connections. Punch down; splicing and crimping tools are designed to match connection housings with specific cable, conductor or fibre sizes. The type and size of tools used shall match those specified by the manufacturers of the Category-6 cables, fibre cables, connectors and termination blocks. Incorrect tools or incorrect use of tools can lead to:

o poor electrical or optical connections,

o physically loose connections,

o contamination of connections with small pieces of conductor (conductive metal) or dust particles, and/or

o Damage to adjacent connections or terminal pins.

4. Training Records – The training and certification records for the installation and construction crews shall be available to show that the cable plant was placed with well trained and knowledgeable workers using industry best practices.

5. Cable Span Characterization – The final acceptance performance tests for the installed system shall be documented and certified to characterize the transmission profile for the network and for individual termination points. Separate profiles of optical loss (OTDR) or transmission performance (e.g., attenuation, impedance and crosstalk) of the key spans will be available and include: a) OSP segment = OTDR scan of the fibre span from the OLT in the CO to the building demarcation point (BDB or PHDB). b) Inside Building Span = From building demarcation point (BDB or PHDB) to FDB and HDB c) Home Span = From HDB to individual connection point (e.g., wall jack or socket).
