Which light source should you use or specify?

Private networks in premises and campus environments are moving towards high-speed applications such as Gigabit Ethernet to handle the ever-increasing bandwidth requirements for faster data transmission. To achieve faster data transmission rates, 1- or 10-Gigabit Ethernet network devices like routers and switches must use high-speed laser light sources rather than slower light-emitting diode (LED) sources. With both lasers and LEDs used for data transmission, learn what type of source should you use when certifying optical fiber links.
