With conventional print and electronic tools, researching statutory material is difficult and time-consuming. One aim consists of deflecting a web of material coated in the vertical position and stretched out in width, in order to introduce it into a conventional flat tenter frame, without damaging the coating. Then the RS transmits M check bit streams to the BS. For the low-loss window at approximately 1430-1530 nm, amplifiers based on nonlinear polarization in optical fibers can be used effectively.
