A DWDM-TDMA PON using carrier distribution with symmetric 320Gb/s capacity is demonstrated over 124km field-installed fibers. The upstream channels feature a 3R 10Gb/s burst-mode receiver with electronic dispersion compensation, burst-mode EDFAs and integrated reflective SOA-EAMs.

We present a hybrid dense wavelength-division-multiplexed time-division multiple access passive optical network (DWDM-TDMA PON) with record performance in terms of reach (135.1 km of which 124 km were field-installed fibers), number of supported optical network units (ONUs-8192) and capacity (symmetric 320 Gb/s). This was done using 32-, 50-GHz-spaced downstream wavelengths and another 32-, 50-GHz-spaced upstream wavelengths, each carrying 10 Gb/s traffic (256 ONUs per wavelength, upstream operated in burst mode). The 10 Gb/s downstream channels were based upon DFB lasers (arranged in a DWDM grid), whose outputs were modulated using a electro-absorption modulator (EAM). The downstream channels were terminated using avalanche photodiodes in the optical networks units (ONUs). Erbium-doped fiber amplifiers (EDFAs) provided the gain to overcome the large fiber and splitting losses. The 10 Gb/s upstream channels were based upon seed carriers (arranged in a DWDM grid) distributed from the service node towards the optical network units (ONUs) located in the user's premises. The ONUs boosted, modulated, and reflected these seed carriers back toward the service node using integrated 10 Gb/s reflective EAM-SOAs (EAM-semiconductor optical amplifier). This seed carrier distribution scheme offers the advantage that all wavelength referencing is done in the well-controlled environment of the service node. The bursty upstream channels were further supported by gain stabilized EDFAs and a 3R 10 Gb/s burst-mode receiver with electronic dispersion compensation. The demonstrated network concept allows integration of metro and optical access networks into a single all-optical system, which has potential for capital and operational expenditure savings for operators.

We demonstrate a DWDM-TDMA PON with symmetric 320Gb/s capacity shared between 16384 customers. The upstream channels were tested in burst-mode and feature low-cost tuneable lasers, monolithically integrated SOA-EAMs, burst-mode EDFAs and a 10Gb/s burst-mode receiver.

A novel DWDM-TDMA PON with symmetric 320Gb/s capacity shared between 16384 customers is demonstrated. Upstream channels were tested in burst-mode and featured low-cost tuneable lasers, monolithically integrated SOA-EAMs, burst-mode EDFAs and a 10Gb/s burst-mode receiver.

This paper presents the first burst-mode system tests of a new hybrid 10Gb/s DWDM-TDM PON. The upstream channels in the network are enabled by combining novel, cost-effective tuneable ONU lasers and a gain-stabilized EDFA (BM-EDFA).

A 40 Gb/s all-optical shift register is demonstrated using a hybrid Mach-Zehnder interferometer with an inverting feedback loop. Previously reported data rate limitations using counter-propagating switching pulses are overcome using a push-pull scheme. (2 pages)
