FTTR beam splitter splitting ratio

FTTR beam splitter splitting ratio

• The FBT splitter offers low cost, common materials (quartz substrate, stainless steel, fiber, hot dorm, GEL), and an adjustable splitting ratio. However, its losses are wavelength-dependent and it offers poor spectral uniformity, cannot ensure uniform spectroscopy, and is temperature sensitive. A split ratio describes how many output ports a splitter has, and how evenly the input optical power is distributed across those ports. For example, a 1:32 splitter takes 1 input signal and splits it into 32 equal (or nearly equal) output signals. In broadband landscape, designing an efficient FTTH network means more than just laying fiber. The real design trade-offs lie in how you split the optical signals, where you locate the splitters, and the ratio you choose for subscriber sharing.

What is a grating beam splitter

What is a grating beam splitter

A grating beamsplitter is an optical device that utilizes the principles of diffraction to split a beam of light into multiple beams, often redirecting them at specific angles. Beamsplitters are often classified according to their construction: cube or plate. Gratings are arrays of apertures characterized by the period, the duty cycle (metal width/period), the material height, and the layout area. We can supply gratings with layout sizes ranging from 60 x 20 mm² to 160 x 90 mm². Coligh specializes in the production of diffractive beam-splitting elements, and we have produced a wide range of 2D Diffractive Beam Splitting Gratings, with the highest array of dots that can reach 33X33 over any area, and with optimal diffraction efficiency of 80%-90%.
