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.
