23、RODUCTION Fibre optic transceivers are used to convert electrical signals into optical signals and vice versa. This specification covers the performance standard for 1 300 nm fibre optic trans- ceivers for Gigabit Ethernet application. The ISO/IEC 8802-3 Gigabit Ethernet standard is used as the basi
24、s for determining the optical characteristics of the transceiver, which operates with a line rate of 1,25 Gbit/s.
