Data transmission over polymer optical fibers
Polymer optical fiber (POF) is a promising transmission medium for providing broadband telecommunication services within the customer's premises. POF offers several attractive features for data transmission such as broad bandwidth and low cost for in-house, access, and LAN applications. This article presents a review on optical transmission systems using POF and their enabling technologies. A summary is given of experimental data links with record capacity over record transmission distances. Standardization activities in POF technology and transmission are reported. To conclude, we discuss trends for further development and research
Status of plastic optical fibres and related technologies
Recent results will be presented in the development of graded index polymer optical fibers (GIPOF) and systems. The bandwidth of the fiber will be discussed and record results of high capacity system experiments that use wavelengths around 645 nm, 840 nm, and 1300 nm are reviewed. WDM experiments are addressed, reporting recent 2.5 Gbit/s WDM transmission results. We also discuss the environmental conditions on the perfonnance of the fiber
Waveguide length and pump power effects on the amplification of europium aluminum doped polymer
Mosquito method is used to fabricate a 50 μm core diameter graded index (GI) multimode Eu-Al doped polymer composite optical waveguide amplifier. In this paper, waveguide length and pump power are varied with an input signal of - 30 dB m. Under a 532 nm laser excitation, 16.27 dB optical gain under an optimal 10 cm waveguide length is observed from forward pumping amplification for a threshold pump power of 23 dB m. Also, the waveguide has been characterized to be 0.83 dB/cm at 617 nm wavelength
