A SIEPON based transmitter sleep mode energy-efficient mechanism in EPON

AA Nikoukar, IS Hwang, CJ Wang… - Optical Fiber …, 2015 - Elsevier
The main energy consumption in computer networks is the access networks. The passive
optical network (PON) has the least energy consumption among access network
technologies. In addition, the time division multiplexing (TDM) Ethernet PON (EPON) is one
of the best candidates to improve energy consumption by time utilization. The optical
network unit (ONU) can utilize the time and save the energy in the EPON by turning off its
transmitter/receiver when there is no upstream/downstream traffic. The ITU-T and IEEE …
