Fibre Optic Cable Characteristics

All fibre cables shall be multimode, graded index. ST style connectors must be used. No physical strain shall be put on the cables. There must be no cable bends of less than a 50mm radius.

Two methods are available for joining fibre cable. Splices provide a permanent, very low loss, fibre-to-fibre connection. Couplers provide temporary connection between two ST style connectors with a loss of 1.2dB. Both methods are permitted on a fibre Network.

The characteristics of the 4100-0143 fibre optic media card are as follows. Mininium Launch Power into a 50/125 cable is 50 uW (-13 dBm). Minimum Launch Power into a 62.5/125 cable is 109.5 uW (-8.6 dBm). The maximum value for the minimum input sensitivity of the receiver is 1.0 uW (-30 dBm).

Maximum line lengths for 50/125 and 62.5/125 cable are shown in the table below.
