Note You can not run GBIC signals (laser light) in both the directions in a single glass fibre. The duplex glass
fibre consists of two glass fibre cores that transmit light in opposite directions. In case of simplex
connection for GBIC port, you need two glass fibres (each transmitting in opposite direction).
