Active optical systems use electrically powered switching equipment for managing signal distribution and directing signals to specific customers. Active optical networks rely on Ethernet technology makes interoperability among vendors easy. In addition active network hardware can be upgraded to acheive higher data transmission rate and without the need to restructure the whole network.
An optic transceiver is a device that uses fiber optic technology to send and receive data. Optic transceivers are active devices and they have electronic components used to condition and encode/decode the data of light pulses. An optic transceiver has a light source to send data as light pulses and photo diode semiconductor light to receive light pulses then convert them into data.
