We experimentally demonstrate an actively-filtered receiver for TDM-PON. Bias-current tuning of a DFB-based-filter enables tracking the wavelength-drift of DML under burst-mode operation. We measure >70% reach increase, >5dB sensitivity improvement,

In this paper, the underestimated challenges of the burst-mode operation in the upstream path of time-and-wavelength-division-multiplexed passive optical networks are analyzed. Various challenges are disclosed, the influence of the associated physica

We demonstrate two new schemes for DFB optical frequency drift reduction up to 13-GHz, which address issues of previously described methods. Density increase scheme requires only modification of digital data in the preamble and is therefore well-suit

To solve the problem of thermally-induced frequency drift in burst-mode transmitters for TWDM access networks, we propose a laser with reduced self-heating, and a simple counter-heating method that demonstrates clear improvement in burst-mode BER mea

First real-time 25-Gbit/s burst-mode operation of an integrated SOA-PIN/TIA receiver for future generation T(W)DM-PON is presented. The device has a 2.7-dB better sensitivity than APD photoreceiver and 13-dB better than PIN photoreceiver at this bitr

An experimental real-time reach and split extension of a 28 Gbit/s electrical duobinary TDM-PON is demonstrated. 50 dB budget is achieved using either remote nodes based on SOA or based on a distributed OLT concept.

An overview of PMD challenges in the upstream path of space and service converged TWDM-PON is provided. Simulations and experiments examine interrelations of loss budget, OSNR, dispersion, cross-talk, laser frequency-drifts and co-existence of servic

An overlayed-modulation technique is introduced to increase flexibility and bit rate per carrier wavelength in access networks. FSK/OOK-experimental results realizing 20&30 Gbit/s, up to 40 km fiber transmission, loss budget >30 dB underline the pote

We propose remote amplification by reusing optical amplifiers in the ONU as in-line amplifiers in a power line independent switched splitter and show that the budget can be substantially increased compared to an unamplified ODN.
