1. Multimode fiber optic cable can be either 50/125µm or 62.5/125µm cabling. Single-mode fiber optic cable must be 9/125µm
2. Maximum distance can be less depending on the duplex mode of the end node and the type of cabling used with the module.
3. Contact a qualified cabling technician for details on the IEEE specifications for Gigabit Ethernet over twisted
pair cabling.
