Fibre Channel Overview
Problems with Fibre Channel
Additional optical cable considerations are as follows:
Cable between two nodes must use the same core size.
NOTE The limitation on mixing core sizes applies only to cable between two
nodes and is only a concern when splicing or connecting optical cables
directly together. Different size optical cable can be used in the same
Fabric between different sets of nodes.
Three core sizes supported by Fibre Channel are: 62.5 micron, 50
micron, and 9 micron.
