Introduction:

  Splitter is a passive device, which does not require external energy, as long as light can enter. After light enters the beam splitter, the ordinary light by wavelength can be divided into the following three types: the near ultraviolet (near UV): 200-380nm
   Vacuum ultraviolet (vacuumUV <VUV>: 10-200nm extreme ultraviolet, extreme ultraviolet (Extreme UV <EUV>): 1-10nm from a human health and environmental point of view, can be divided into UVA (315 ~ 400nm), UVB (280 ~ 315nm ), UVC (280nm or less).

 Splitter from the entrance and the exit slit, mirrors and dispersive elements, whose role is required for resonance absorption lines separated. Key components of the beam splitter is dispersive element commodity instruments are now using the grating. Atomic absorption spectrometer resolution of less demanding on the splitter, once opened can distinguish three lines of nickel Ni230.003, Ni231.603, Ni231.096nm standard, adopting Mn279.5 and 279.8nm three lines instead of Ni Verification resolution. Grating placed after the atomizer to prevent any unwanted radiation from inside the atomizer into the detector.
   Optical communications era splitter is a component of the formation of EPON network is a passive connection OLT and ONU equipment, its function is to distribute downlink data and uplink data centralization. Splitter with one upstream optical interface, a number of downstream optical interfaces. From the upstream optical signals over optical interface is assigned to all the downstream optical interface to transfer out, was assigned downlink optical signals over the optical interface from the unique upstream optical interface transfer out. Only the optical signal from the upstream to the downstream optical interface optical interface when the optical signal intensity / light power will drop, from downstream to upstream optical interface optical interface when the same. Each downlink optical interface out of the optical signal strength may be the same or different.
Each fiber has two joints which have 0.2db attenuation and a side optical fiber and another fiber attenuation through a connector on the 4x0.1 + 1x0.4 = 0.8db loss, and generally the originator of light sometimes because of the high power drops to the terminal as well as a high side power error
epon in the physical layer using the PON technology, using Ethernet protocol at the link layer, using PON Ethernet topology to achieve access. In an optical network, in fact, epon WDM achieve multipoint structure, naturally we need a splitter.
