Fibre optic media card settings
New installations use the 746-109 fibre optic media card. The 565-261 and 566-376 cards are older cards
installed in some existing systems. The 565-261 and 566-376 cards do not have adjustable settings.
On the 746-109 card, link JW1 adjusts the optical output power to suit the path loss, see Table 7.
