An innovative setup for thorough jitter characterization in fronthaul links is introduced. Tests have been carried out on an operating LTE fronthaul link measuring jitter impact on BER, EVM and frequency deviation.
A self seeded WDM PON solution is evaluated at 1.25Gb/s and 2.5Gb/s in order to address optical budget, rise and fall time and jitter performances issues.
We present a new WDM-PON architecture based on amplified self-seeded RSOA creating an external cavity source. The SMF cavity length can reach up to 45km. Transmission at 2.5Gb/s are demonstrated.
The paper describes how a combination of different innovations can improve the power consumption per subscriber of a wireline access and aggregation network by 50x and the energy efficiency per transferred bit by 400x.)
We evaluated different km-long WDM PON laser sources based on amplified self-tuning solution. RIN reduction and data cancellation are demonstrated by using saturated SOA inside the cavity. The BER performance at 2.5Gb/s was enhanced with up to 50km cavity length.
Performances of a symmetrical 10G-PON prototype are explained and a Reach Extender for both G-PON and 10G-PON systems based on only two SOA is proposed.
A WDM-PON system based on self-seeded RSOA is evaluated to provide long reach and high bit rate. For the first time, a maximum reach of 90km and a maximum bitrate of 4.9Gbit/s are achieved.
Energy saving is compared for long reach PONs using passive or active scenarios. Inserting active equipments such as Extender Boxes lead to energy saving when the number of COs and filling ratio are optimized.
We compare the performances of IMDD AMOOFDM transmissions in both amplified and unamplified configurations for long distance PON networks with 1:32 and 1:64 split ratios. Up to 40 Gb/s bit rate has been demonstrated.
A ring+tree PON is demonstrated from a 78 km reach rural to an urban 1:128 split configuration with field-deployed fibers at >31 dB budget and RSOA or SOA/REAM at the ONU.
We experimentally demonstrate AMOOFDM transmissions at 11.5Gb/s over 513km uncompensated standard single mode fiber (SSMF) and 30Gb/s over 650km dispersion managed fiber (DMF) through intensity modulation and direct detection.
The built multi-layer SARDANA prototype proves the feasibility of extended hybrid DWDM/TDM-XGPON FTTH networks with resilient optically-integrated ring-trees architecture, supporting broadband multimedia services.
This paper presents a view of the trends and perspectives in the next generation of optical access solutions following the 10Gbit/s Passive Optical Networks.
A wide-band SOA is used for amplification of both downstream signals from G-PON and 10G-PON access networks. BER measurements showed a performance of 42dB on optical budget but also pointed out requirements on the SOA to improve this performance.
An OFDM transmission system is amplified through SOA or EDFA to provide an access network at 10Gbit/s with increased optical budgets. Bit-rate optimization and BER measurement characterize amplifier's behaviour with OFDM signals for access network.
We experimentally demonstrate the use of AMOOFDM format as a cost effective solution for colorless source WDM-PONs based on spectrally sliced ASE source (SLED, RSOA and pre-selected RSOA).
We present here the main results for reach extension in passive optical network (PON) technologies. Both passive and active architectures integrating several multiplexing techniques are studied, and they provide promising results for the future generation of optical access networks. Extender boxes based on optical amplification and optical-electrical-optical (OEO) repeaters are evaluated over a standardized...
We propose to increase the reach and reduce the number of central offices by traffic aggregation of four G-PONs, achieving 10 Gbit/s downstream traffic. Upstream burst mode traffic at 1.25 Gbit/s is converted into continuous mode.
This paper considers the main technical challenges for optical access network deployment. Technological evolution of broadband optical networks is discussed with the need for adapting both metropolitan and access networks to the customer services demand evolution.
