or in EN 50577.
The test determines the survival time for circuit integrity of the optical fibre cables when exposed to fire under
the conditions either given in EN 50200 or given in EN 50577.
EN 50200 is limited to cables with an overall diameter not exceeding 20 mm.

3 Circuit integrity (Continuity of signal supply)
The criteria that are used for defining fire resistant optical fibre cables are deemed to demonstrate the ability
of the cable to maintain a reliable signal transmission when subjected to fire.
Circuit integrity is based upon continuity of optical signal supply.
This clause specifies characteristics that shall be used to define the continuity of signal supply / maintenance
of circuit integrity (continuity) under fire conditions for optical fibre cables.
The circuit integrity i.e. continuity of optical signal supply is deemed to be maintained if the maximum
increase in attenuation does not exceed the value given in Table 1 during the test duration.
Continuity of optical signal supply (see 4.4) can generally be performed by two methods:
(A) Monitor individual fibres for attenuation change;
(B) Loop-back measurements: this method splice
