Note:
P59x interface units should be mounted as close as possible to the telecommunications equipment to minimise interference
on the electrical connections.
3.1.6.2.1 INDIRECT CONNECTION - FIBRE (IEEE C37.94)
An 850 nm fibre-optic interface can connect directly to a multiplexer supporting the IEEE C37.94 standard. 850 nm
multi-mode optical fibres, either 50/125 mm or 62.5/125 mm are suitable. BFOC/2.5 type fibre optic connectors are
used.
