3. Make these checks:
• All fiber cabling is of the same type; do not mix multimode and single mode cables.
• The fiber optic cable is within the specifications and loss budget of the optic interface
module.
• The line length between the 9155 and the remote link does not exceed the allowable loss
budget or overdrive limit.
• All host modules in the link are turned on.
