“…After transmission over 20 or 40 km, the power penalty is negative, which is due to the pulseshaped change as shown in Figures 5 (b) and 5(c). Usually, the sharp "1"s will lead to a negative power penalty [16].…”

Roskosch, and M. Vossiek, Cost-minimized 24 GHz pulse oscillator for short-range automotive radar applications, 33rd European Microwave Conf.ABSTRACT: Fiber dispersion in standard single mode fiber (SSMF) limits the maximum delivery distance for the optical millimeter (mm)wave signals generated by double sideband modulation and vestigial sideband filtering. We propose and experimentally demonstrate a novel scheme to generate mm-wave signals without dispersion limitation. The power penalty for 2.5-Gbit/s mm-wave signals carried by 40-GHz radio-frequency after transmission over 80-km SSMF is smaller than 0.5 dB. ABSTRACT: A miniature and harmonic control patch dual-mode bandpass filter (BPF) with transmission zeros for application of global positioning system (GPS) is proposed. The right crossed-slots of the patch resonator are used to determine the main passband frequency of the BPF. In this study, by using a pair of square etched areas (SEAs) acted as perturbation elements, the dual mode filtering performance can be excited and two transmission zeros located on either side of the passband are clearly observed. It is found that two transmission zeros can improve the selectivity of the BPF as well as the stopband rejection effectively, thus avoiding the interference from other communication systems. The measured results of the fabricated BPF are in good agreement with full wave simulation.Figure 1 Geometry of the proposed patch dual-mode bandpass filter with transmission zeros and harmonic control

“…Moreover, the use of SOAs as in-line amplifiers is very suitable for bi-directional transmission in local and metropolitan systems and networks because of the lower cost of SOAs and no need for optical isolators as often used in different types of amplifiers such as erbium doped fiber amplifiers (EDFAs) [7].…”

This paper characterizes the gain and the carrier density responses of a semiconductor optical amplifier (SOA). In order to achieve the switching functions in SOA-based optical switches, such as Symmetric Mach-Zehnder (SMZ), the effect of the input signal on the total gain response of the SOA is investigated. The theoretical operation principle is demonstrated using a segmentation model that employs the complete rate equation with third order gain coefficients. Results obtained show the input boundaries and requirements in which the SOA can be efficiently used as an amplifier and as a switch.

“…Bidirectional transmission over a single optical fiber is an effective way to increase the capacity of conventional unidirectional wavelength division multiplexed (WDM) transmission systems [1,9]. Bidirectional transmission can reduce the cost of metro and access networks due to sharing of optical fiber and inline amplifiers.…”

“…Recently, crosstalk-suppression tech- Figure 6 Characteristics of the output power vs. temperature increase niques have been proposed, including the polarization-multiplexing technique [6], wavelength-modulated signal [5], and holding light injection [7]. The constant-intensity modulation format is in principle immune to XGM-induced crosstalk in SOAs [9]. DPSK has been used to demonstrate unidirectional transmission of nine 25-GHz-spaced channels at 12.5 Gb/s [8].…”

Bi-directional transmission of 8x10Gb/s DPSK signals over 80km of SMF-28 Fiber using in-line semiconductor optical amplifier

Abstract: We report the bi-directional transmission of 8x10Gb/s signals using an in-line SOA over 80km SMF-28 with matching DCF for the first time. Our results suggest very promising applications for bi-directional transmission in metro and access networks with simple configuration and low cost.
