Abstract: PURPOSE: To prevent a monitor information signal of each optical repeater superimposed onto a main signal light amplified directly and optically at each optical repeater from being in crosstalk among the optical repeaters in the optical fiber relay transmission system comprising optical repeaters in multi- stage connection via the optical fiber transmission line. CONSTITUTION: Each optical repeater 100 is provided with an optical direct amplifier 3 applying optical direct amplification to a main signal light obtained by superimposing the monitor information on the digital main signal light sent from an optical repeater at a pre-stage, and an external modulator 7 applying optical intensity modulation to monitor information of its own repeater to the signal light at a frequency different from that for other repeaters. Then the signal is superimposed at a frequency different and specified to each optical repeater 100 through external modulation.  Thus, a different frequency is assigned from each optical repeater 100 for the frequency used to superimpose the monitor signal onto the main signal light, then even when the optical relay transmission system is formed through multi-stage connection, the monitor information is propagated without interference.

Abstract: PURPOSE:To reduce the variation of the image height on an image carrier caused by the deviation of an image surface and to improve an image quality by setting the ftheta lenses whose condensing power in a subscanning direction is larger than the condensing power in a main scanning direction on the side of a scanning mirror. CONSTITUTION:The plural Ftheta lenses 40a, 40b which have a larger condensing power in the subscanning direction vertical to the main scanning direction than condensing power of the main scanning direction are set in an ftheta lens system. The condensing power in the subscanning direction of the ftheta lens 40a on the side of the scanning mirror 34 of the ftheta lens system consisting of the plural lenses 40a, 40b is larger than the condensing power in the main scanning direction; therefore, the height of the laser beam passing ftheta lens 40b on the side of the image carrier 38 is reduced and the angle of incidence of the laser beam from the ftheta lens system to the image carrier 38 is reduced. The variation on the subscanning direction of the laser beam on the image carrier 38 is reduced even if the image carrier 38 surface makes the deviation, and the image quality is improved.
