“…A solution is to increase the sensitivity of the receiver by adding an optical amplifier immediately before the receiver to form an optically preamplified receiver. Such devices operating at 10 Gb/s have been reported with sensitivities of −37.2 dBm at BER = 10 −9 [6]. Therefore, using two amplifiers at the local-exchange site with an optically preamplified receiver would potentially constitute a feasible system.…”

Abstract-Optical-access networks have been developed to remove the access-network bandwidth bottleneck. However, the current solutions do not adequately address the network economics to provide a truly cost-effective solution. Long-reach optical-access networks introduce a cost-effective solution by connecting the customer directly to the core network, bypassing the metro network, and, hence, removing significant cost. This paper charts the design and development of a 1024-way-split 100-km 10-Gb/s symmetrical network, which experimentally proves the feasibility of long-reach optical-access networks for both the upstream and downstream transmission.

“…The transmitter of 10Gb/s conventional duobinary is composed of a duobinary precoder, LPF, and Mach-Zehnder modulator driven at the transmission null point. The length of pseudorandom bit sequence (PRBS) was 2 7 . A LPF had a fourth-order BesselThomson response and its 3dB bandwidth was 2.5GHz.…”

“…The receiver model consists of an optical amplifier, followed by a Gaussian band-pass optical filter, a square law detector, and a fourth-order Bessel-Thomson electrical filter [7]. The shot noise, beat noises generated by signals and amplified spontaneous emission (ASE) noise, and the receiver circuit noise were considered in the calculation of BER, which was optimized with both threshold level and sampling time [8].…”

This paper describes the transmission performance of the 10Gb/s phase-modulated (PM) duobinary modulation format, compared with the conventional duobinary modulation format using a low-pass filter (LPF) in cascaded optical networks. We theoretically investigate the transmission characteristics of both modulation formats with considering the effect of narrowing bandwidth of multiplexers (MUX) and demultiplexers (DEMUX) at cascaded nodes with different fiber launching powers (FLP). It's shown that PM duobinary signals, at the FLP of 9dBm, can be transmitted over 3 nodes (up to a distance of 1,200km) with only 1.25dB power penalty.

We investigate theoretically the tolerance of 40 Gbps phase-modulated (PM) duobinary signals using a vestigial sideband (VSB) filter on impairments which occurred in dense wavelength-division multiplexing (DWDM) systems, compared to the conventional duobinary signals. Our simulation results show that PM duobinary signals can t have the gain on the spectral efficiency achieved ' by utilizing the VSB filtering technique. In order to increase the spectral efficiency, they indispensably require to be transmitted at the optimum bandwidth of multiplexer (MUX) and demultiplexer (DEMUX) since they are susceptible to inter-channel crosstalk. It is also shown that the PM duobinary modulation format has a large tolerance on self-phase modulation (SPM) and cross-phase modulation (XPM) under the condition which MUX and DEMUX have been tuned at an optimum bandwidth; it has 1.2 dB power penalty at the fiber launching power (FLP) of 15 dBm and the channel spacing of 50 GHz.
