d. Use screened cables to comply with the
EMC requirements and reduce the
possibility of external interference.

Each link in a network may be either copper-
conductor cable or optical fibre.
Caution: To ensure specified performance
use only 2-core, screened cables.
On no account must multi-core
cables be used.
3.3.1 Fibre-optic Cable Limits
The fibre-optic link used by the ID
has the following specification:
a. Connector style
b. Link
c. Wavelength
d. Fibre Type
Parameter
Optical Power Budget
50/125μm Fibre
Optical Power Budget
62.5/125μm Fibre
Notes:
1 For a typical 62.5/125 cable, attenuation is
2.8dB/km which gives a typical link length
of 15/2.8 = 5300m.
2 Using worst-case figures, attenuation of
4.5dB/km gives a link length of:
8/4.5 = 1800m.
3 For a specific design, substitute the
attenuation figure for the fibre to be used
into the calculation.
4 Allowance should be made for any
additional splices or connectors used.
