Q

Which regulation applies to optical fibre cable construction?

A

JSP604

2
Q

What minimum classification of cabling is required to be installed within underground or windowless MOD facilities?

A

EuroClass Cca

3
Q

If lower classification cabling is used externally, at what distance is it required to be terminated when entering a building?

A

terminated inside the building, within 2 m of the point of internal penetration of the external fire barrier (e.g. floor/ceiling/wall)

4
Q

What is the requirement for redundant cabling as specified in both BS 8492 and JSP 604?

A

that they add to the total potential fire load of a building and thus BS 8492 requires that they are removed.

5
Q

All cabling must be supplied with supporting paperwork which highlights the performance of the cabling, what is this known as?

A

Declaration of Performance (DoP);

6
Q

What information should this documentation contain?

A
  • Manufacturer’s name.
  • Product code.
  • Traceability.
  • Use of this product.
  • AVCP System.
  • Notified Body.
  • Declared performance and respective standards.
  • Date and manufacturer’s stamp.
7
Q

State the characteristics of external optical fibre cabling?

A
  • Moisture and chemical resistant.
  • Tolerance to variations in temperature.
  • Strain-tensile strength.
  • Abrasion resistant.
  • Crushing resistant.
  • Ultra-Violet resistant.
  • Rodent resistant.
  • Lightning/electrical damage.
8
Q

State the characteristics for internal grade optical fibre cabling?

A
  • Ease of termination.
  • Flexibility.
  • Riser installation.
  • Flame-Retardant.
9
Q

What are the correct sizes (in microns) used for Secondary and Primary coated optical fibre?

A

Primary 400Microns

Secondary 900Microns

10
Q

What are the minimum labelling criteria of optical fibre cabling?

A

All cables shall be labelled at both ends and on both sides of any point at which the cable transits a sealed passage.

11
Q

What information should a cable label specify?

A
Originating location/connection, Parenting system, 
Type of cable, 
Number of cores, 
Unique serial number, 
Destination location/connection detail.
12
Q

What chemical is most commonly used to clean optic fibres and connections?

A

IPA (Isopropyl Alcohol)

13

Single Ruggerdised
Stranded Secondary Coated or Distribution Cable
Breakout Cable
Unitary Single Loose Tube
15
