Title: Optical communication system
Inventor: TAKAHASHI HIDEO
IPC: H04B10/67
Filed: 1988-05-30
Abstract: PURPOSE:To extend the light transmitting distance to the title system so as to expand the applicable extents of an low-cost or low-power consumption laser diode (LD) by adding not only the optical output of the facet in front of the LD, but also that of the facet at the rear of the LD to a front optical transmission line so as to increase the optical output of the line. CONSTITUTION:The LD 1 is driven by means of a driver 3 through an equalization circuit 2 based on a pulse modulation input signal and its front and rear facets respectively emit optical signals. The optical output of the rear facet is inputted to a directional coupler 7 through a SELFOC lens 4, fiber end 5, and optical fiber 6 and divided into optical fibers 8 and 9. The optical output led to the optical fiber 8 is fed back as an auto-power control signal for deciding the bias voltage of the driver 3. The optical output from the front facet is led to an optical fiber 17 through a fiber end 16 after the output is condensed by means of a SELFOC lens 15. The optical output of the front facet led to the optical fiber 17 is added to the optical output from the optical fiber 9 by means of a directional coupler 18 and transmitted to a receiving side through an optical fiber 19.
