Abstract
The invention discloses an optical divider comprising a simple optical fiber coupler, a low channel optical filter and a planar waveguide type optical divider body. A PLC optical dividing circuit is connected in the internal part of the planar waveguide type optical divider body. The PLC optical dividing circuit is arranged at the end surface of a semiconductor substrate via a conductive wire. The upper end of the semiconductor substrate is provided with an optical divider output interface. The upper end of the output end of the optical divider is provided with an optical wave synthesizer. The simple optical fiber coupler is connected with a multichannel optical fiber echo module via the conductive wire. The multichannel optical fiber echo module is coupled with an optical dividing and fiber dividing box. The optical divider is compact in structure, small in size, reasonable in design, simple and convenient in manufacturing and relatively low in cost. The optical divider is uniform in optical dividing so that signals can be uniformly allocated to users. Besides, loss is not sensitive to optical wavelength so that the transmission requirements of different wavelengths can be met.
