“…We have used an ideal transmitter with return to zero Gaussian pulses. Moreover, in order to better exploit the already installed cables, we assume the use of standard G. 652 fibres, adopting the dispersion management method [4] to achieve IM-DD transmission at 10 Gbit/s and 40 Gbit/s, on long and very long distances.…”

Energy consumption is becoming a fundamental topic also for telecommunication networks, where the implementation of "green" infrastructures is required. In this paper, we report a numerical investigation about energy saving in a transport network both exploiting the transmission properties that permit to reduce the number of in-line equipments (optimizing wavelength path assignment) and switching off optical links when the traffic load decreases. In particular, we investigate a European transport network based on N × 40 Gbit/s transmission and the Italian network based on the M × 10 Gbit/s transmission. © 2010 Elsevier B.V.

“…The last dispersion compensating scheme in the present work uses a CFBG at the end of each span as depicted in Fig 4. The link simulation in the FBG part is carried out by transfer matrix approach [6,7]. The grating is designed with symmetric hyperbolic tangent with respect to the mid-point of the grating length.…”

The paper compares the effectiveness of four dispersion compensating schemes such as using dispersion compensating fiber (DCF), optical phase conjugator (OPC), OPC and distributed Raman amplifier (DRA) combination and apodized linearly chirped fiber Bragg grating (CFBG) in terms of the eye-opening penalty (EOP) at the end of the link. The comparison is also carried out with different modulation formats.

“…With the use of semiconductor optical amplifiers [18][19][20], Mach-Zehnder interferometers [21][22][23], ring waveguides and resonators [24,25], and nonlinearly birefringent fibers [26][27][28][29][30], different kinds of OOK-to-PSK and NRZ-to-RZ format convertors were proposed and comprehensively investigated in past decades. To upgrade the OTDM transmission up to 40 Gbit∕s or higher, the external encoding of a continuouswave (CW) laser with a nonlinearly biased modulator [31,32], or the NRZ-to-RZ in versatile photonic devices [33][34][35][36], were also proposed. The synthesizer-free pulsed RZ signal and clock with ultralow jitter at high repetition rate extracted [37,38] or generated [39,40] from versatile sources, especially those demonstrated with the assistance of self-starting optoelectronic oscillators (OEOs), have emerged as novel optical carriers for high-bit-rate OTDM communications.…”

A self-starting pulsed encoding of a MachZehnder intensity modulator (MZM) is demonstrated to generate a 40 Gbit∕s return-to-zero binary phase-shiftedkeying (RZ-BPSK) data stream by using the optoelectronic feedback loop. By driving the MZM with an optoelectronic oscillator, both the electrical clock and the optical pulse train at 40 GHz can be extracted to deliver and trigger the synthesizer-free 40 Gbit∕s RZ-BPSK data. The pulsed RZ carrier with a pulsewidth of 10.5 ps provides a jitter as low as 150 fs and an extinction ratio as high as 7.8 dB, which is particularly suitable for the RZ-BPSK transmission at 40 Gbit∕s. The back-to-back transmitted synthesizerfree 40 Gbit∕s RZ-BPSK data with a pattern length of 2 23 − 1 reveals a receiving power sensitivity of −16.3 dBm at the requested bit error rate of 10 −9 by setting the DC bias of the BPSK demodulator at 3.76 V. After 25 km single-mode-fiber transmission, the RZ-BPSK data indicates a power penalty of 4 dB when compared with the back-to-back case.
