An enhanced WDM optical communication system using a cascaded fiber Bragg grating

Dispersion compensation of optical systems utilizing fiber Bragg grating at 15 Gbits/s

“…It can be saw that the eye-opening or eye gap is much higher and clearer because of the high quality of receiving signals. Hence, the FBG offers better dispersion compensator for WDM long-haul optical communication systems, when compared to the existing reported work in the literature with 5km cable length and 10 Gbit/s [12,24], single-channel in the proposed design used 4channel [20], 20 Gbit/s NRZ transmission system over 210km long single-mode fiber (SMF) but with chirped fiber Bragg grating (CFBG) [24], 180Km long single-mode fiber also with chirped fiber Bragg grating [25], over 210 km long SMF but with CFBG [19] design the dispersion compensation with double EDFA [11], cascaded FBG system is proposed to reduce the dispersion in the optical signal in single-mode optical fibers for distance 200km [26]. And additional with 10km optical fiber length and 10 Gbit/s [11].…”

A comparative study of chromatic dispersion compensation in 10 Gbps SMF and 40 Gbps OTDM systems using a cascaded Gaussian linear apodized chirped fibre Bragg grating design

“…The Bragg wavelength along the core of the chirped fibre grating when a frame of reference along the +z direction is considered and with a refractive index, n ( z ), is given by Eq. (4) as in [ 19 ]: …”

“…The refractive index s also a function of the effective index of the fibre, the average change in the index modulation and the apodization function as expressed in [ 19 ] by Eq. (7) : …”

“…In [ 18 ], Q-factor results were obtained for different SMF lengths using a core refractive index of 1.47: for an SMF length of 150 km for example, corresponding BER and Q-factor results were found to be respectively 1.63×10 −37 and 12.74 dBm. In [ 19 ], A. F. Sayed et al. presented a cascaded UFBG design to enhance WDM optical transmissions and used Optisystem 7 to simulate results for different fibre lengths, input power and FBG length.…”

An N-Port Universal Multimode Optical Router Supporting Mode-Division Multiplexing

“…Optical network-on-chip (ONoC) is a new interconnection technology that replaces electrical connections with optical connections, overcoming the shortcomings of traditional electrical interconnections, and has broad application prospects in high-speed communication networks due to its low latency, ultra-high bandwidth, and distance-independent power consumption [1][2][3][4]. In order to further improve the channel capacity of optical interconnection, many (de)multiplexing technologies have been proposed and studied, such as wavelength-division multiplexing (WDM) [5][6][7][8], code-division multiplexing (CDM) [9][10][11], and time-division multiplexing (TDM) [12][13][14]. Among these multiplexing technologies, the research on WDM technology is the most extensive.…”
