چکیده
In this letter, a bidirectional symmetric 100 Gb/s/ $\lambda $ coherent passive optical network (PON) scheme with simplified unit (ONU) transceiver is proposed and experimentally demonstrated. the scheme, downstream signal generated in dual-polarization transmitter Alamouti-coding at line terminal (OLT) side then received by single-polarization heterodyne receiver ONU side. The upstream low-cost C-band electro-absorption modulated laser (EML) standard integrated OLT experimental results show that more than 30 dB power budget achieved after 25 km single mode fibre transmission for both . cost maintained low as required bandwidth of optoelectrical device >25 GHz local oscillator can be 4 dBm.

Optical transceivers are demonstrated with error-free performance in TWDM PONs. Integrated OLT transceiver in CFP-module transmits 10dBm power and achieves -36dBm sensitivity. Low-cost tunable SFP+ ONU transceiver can be tuned over 4 channels with 4dBm transmitted power and -26dBm sensitivity. Introduction Rapid growth of internet traffic, driven by the proliferation of video services, continue...
متن کاملONU migration in dynamic Time and Wavelength Division Multiplexed Passive Optical Network (TWDM-PON).
We propose a novel Optical Network Units (ONU) migration mechanism within the Time and Wavelength Division Multiplexed PON (TWDM-PON) framework by rearranging the working ONUs to a minimum number of wavelengths and turning off the rest to save power. We show through simulation that the number of working wavelengths can be minimized up to a theoretical lower bound, e.g. 23%, under the typical ON...
متن کاملBidirectional coherent classical communication
A unitary interaction coupling two parties enables quantum or classical communication in both the forward and backward directions. Each communication capacity can be thought of as a tradeoff between the achievable rates of specific types of forward and backward communication. Our first result shows that for any bipartite unitary gate, bidirectional coherent classical communication is no more di...
متن کاملFast Wavelength Switching Digital Coherent OFDM Transceiver
Digital dynamic frequency offset removal and DC pilot tone assisted phase noise compensation enables the use of commercially available DS-DBR lasers as both the transmitter and LO in a coherent wavelength switched OFDM transceiver. A 1.5dB penalty relative to low linewidth static lasers is demonstrated under fast wavelength switched operation. Introduction The combination of higher order spectr...
متن کاملCompatibility between coherent reflective burst-mode PON and TWDM-PON physical layers.
We discuss the compatibility between reflective PON architectures and the recently defined ITU-T G.989.1 TWDM-PON. Focusing on the upstream, we experimentally demonstrate that, by using burst-mode coherent detection at OLT, reflective PON can achieve the specification target set for TWDM-PON, without requiring precise wavelength accuracy at ONU. Compared to the companion ECOC 2013 paper, we inv...
