Distribution of Broadband Services Over 1-mm Core Diameter Plastic Optical Fiber for Point-to-Multipoint In-Home Networks

Recent Advances in Wavelength-Division-Multiplexing Plastic Optical Fiber Technologies

“…An insertion loss for a future PF-GIPOF 4-λ multiplexer/demultiplexer device of around 2dB per channel [93,94] is considered. Such a performance is better in terms of insertion loss with respect to PMMA-GIPOF based splitters which can provide insertion losses greater than 6dB (in the symmetric-case) [95]. Consequently, the power budget of the WDM system, consisting of one PF-GIPOF based multiplexer or demultiplexer device at each side of the optical fiber link, results in a 5dB power reduction per channel, if an optical crosstalk of 1dB is also considered.…”

Efficient Multiplexer/Demultiplexer for Visible WDM Transmission over SI-POF Technology

“…But the latter solution increases the system power consumption and is only suitable for scenarios where working outside the eye-safety-limit is allowed [5], [13]. Mux/DeMux devices with ILs 3.5 dB per ch allow to establish SI-POF visible WDM systems with transmission power per ch near to the eye safety limit (<1 mW), that can be used in network topologies [14], where the fiber containing all the WDM chs is kept away from the end user. Therefore, the development of Mux/DeMux devices with low ILs and higher ch counts than the current proposals is essential in order to implement efficient visible WDM SI-POF links, working near the eye-safe-limit and using low-power technology [9], especially for in-home and office networks [14].…”

Inscription of narrow bandwidth Bragg gratings in polymer optical fibers

“…However, polymer optical fibers (POFs) are starting to be considered a viable alternative to silica fibers (SF) in applications such as short distance transmissions 1,2 , sensing 3,4 , terahertz waveguides and filters 5 , in-building networks 6,7 , and radio over fiber systems 8 . One of the major drawbacks pointed to POFs is the greater attenuation coefficient as compared to SF, a fact that limits their applications.…”

“…POF fiber Bragg gratings (POF FBGs) are an attractive technology due the easy integration in optical components and to be cost effective for data communication 1,2,[6][7][8][11][12][13][14] , lasers 15 and sensor applications 3,4,9 . POF FBGs have been reported in step index POFs (SI-POF) 9 and microstructured POFs (mPOFs) 3,9 including both singlemode (SM FBGs) and multimode fibers (MM FBGs).…”
