Cable Television (CATV) is designed with erbium-doped amplifier-repeated system that uses an external light -injection technique and a directly modulated wave using amplitude modulation. The external lightinjection technique can greatly enhance the frequency response of the laser diode, and hence improve the overall performance of the fibre optical CATV system. It implemented using Optiwave Optisystem 10.0.

“…These parameters can be seriously degraded by stimulated Brillouin scattering (SBS), stimulated Raman scattering (SRS), and fiber dispersion effects in 1550-nm fiber optical CATV transport systems. Several ways have been proposed to solve these problems such as employing an externally modulated transmitter and differential detection through two fiber links [3], using external light injection locking or sideband filtering techniques [4,5], the CSO and CTB performances can be improved [6][7][8]. Nevertheless, an expensive externally modulated transmitter as well as sophisticated differential detection, external light injection locking, and sideband filtering techniques are required.…”

“…As the user receives the channels transmitted from the headend, an ID code verification will be excuted to verify whether the channel is the user desired. Meanwhile, to avoid the interference of other channels, we choose two channels with different frequencies by using two converters at each moment which avoid the expensive equipment and complex systems that are required by the system of full channel loading [3][4][5][6][7][8][9].

This study proposes a two-channel fiber optic cable television (CATV) transport system based on Fabry–Perot laser diodes (FP-LDs) with a split band technique. To reduce the interference between channels, we apply the split band technique to two channels with different frequencies by using two converters at each moment. In this two-channel transmission scheme, composite second-order (CSO) and composite triple-beat (CTB) distortions induced by the systems are possibly confined in unused channels and result in good transmission performances. Through a 40 km standard single-mode fiber transmission, excellent performances of carrier-to-noise ratio (≥50 dB), CSO (≥70 dB), and CTB (≥72 dB) are obtained using the proposed fiber optic CATV transport systems. The proposed systems employing FP-LDs with a split band technique are also simpler and more cost effective than conventional externally modulated systems.

“…In an ROF transmission system, the injection-locked technology plays an important role in improving the performance of the laser diode such as increasing the frequency response, sidemode suppression ratio, 7 and reducing the frequency chirp. 8 In contrast, bidirectional light wave transmission systems simultaneously transmit downlink and uplink signals.…”

Abstract. We propose a bidirectional transmission system based on stimulated Brillouin scattering effect and injection-locked distributed feedback laser to achieve an optical single-sideband modulation for downlink transmission. We reuse the transmitted light through phase modulation for uplink transmission to avoid interference of both signals in a bidirectional transport. After a 25-km single-mode fiber transmission is completed, a sideband power ratio of >15 dB is observed in the downlink transmission, and the power penalty of the system is <1 dB. In our proposed bidirectional transmission system, the performances of bit error rate analysis are good. © The Authors. Published by SPIE under a Creative Commons Attribution 3.0 Unported License.
