“…We evaluated the packet delay for a 10 Gb/s Ethernet Passive Optical Networks (EPON) with cyclic sleep (as described in [6,26]) for low utilization levels as would be typically expected in such a system. We used a 50% duty cycle, D = 0.5, where the system sleeps for a time T o f f , which includes both wake and sleep transition overheads.…”

Abstract:On-off scheduling of systems that have the ability to sleep can be used to extend system idle periods and enable greater opportunities for energy savings from sleeping. In this paper, we achieve a theoretical understanding of the delay behavior of on-off scheduling as it may apply to communications links and other systems capable of sleeping. We consider a single-server coalescing queue with a scheduler that schedules on-off periods for the server in order to extend idle periods of the downstream link. At the start of an off period (duration T o f f ) the server stops serving jobs immediately if idle, or after processing a job already in service. Service of any queued and arriving jobs begins at the start of the next on period (duration T on ). On and off periods are fixed. We solve for the scheduling queue behavior as a function of T o f f , T on , interarrival time t, service time x, and time of first arrival g for periodic job arrivals. Our results are closed form and have both theoretical and practical significance.

“…An example of a communications link that can be placed into a sleep state is XG-PON (10 Gb/s Passive Optical Network). The XG-PON standard specifically describes a cyclic sleep mode to save energy [6,26]. Energy Efficient Ethernet (EEE) also allows for idle links to be placed into a low-power idle (LPI) mode [5].…”

“…components excluding TM and RM) as Common Modules (CMs). These CMs need to be always on regardless an ONU's state and their total power consumption, defined as P CM , is 0.7 W [9]. Similar to [5], [6] we assume that an ONU turns on RM and TM only when they have certain function to perform.…”

“…These numbers imply that the RM power consumption, defined as P RM , is 1 W (= 1.7−P CM ). When an ONU is in the Active state, it consumes 4.69 W [9]. Hence, the power consumed by TM, expressed as P T M , is 2.99 W (= 4.69 −P RM −P CM ).…”

Evaluating Energy Efficiency of ONUs Having Multiple Power Levels in TDM-PONs

et al. 2013

Abstract-A TDM Passive Optical Network (TDM-PON) proposes the use of sleep modes for Optical Network Units (ONUs) to maximize Energy Efficiency (EE). When an ONU manages a sleep mode, it needs to turn on and off some of its components based on communication requirements. Hence, an ONU ends up with multiple power levels. Existing analytical models for evaluating EE consider that an ONU has only two power levels. However, we have found in some literature where an ONU can have more than two power levels. In this letter we propose an analytical model to quantify the EE of an ONU having more than two power levels. We demonstrate the accuracy of the model by means of simulation under two different sleep interval deciding algorithms.Index Terms-TDM-PON, energy efficiency, sleep mode.

“…Passive optical networks satisfy the rising bandwidth demands in the access network along with service provider central offices (COs) and consumer site by providing a powerful point to point or point-to-multipoint solution [1]. First of all, time division multiplexing PON provides BPON with downstream of 622 Mbps, EPON with 1.25Gbps downstream and GPON with 2.5Gbps downstream.…”

ABSTRACT:In this paper, the performance of Gigabit Passive Optical Network using 2Gbps downstream transmission has been investigated. The entire optical network unit (ONU) is implemented to examine the transmission capability. A 1: N splitter is used as a passive optical network which creates communication between central offices to different users. The system deployed with 64 users is investigated on the basis of optical transmission parameters such as Quality Factor, Bit Error Rate and Receiver Sensitivity. It is observed that the maximum transmission distance of 21 km is achieved with acceptable bit error rate of 1.8e-10 and quality factor of 6.2.
