Title: Connection switching system for optical network
Inventor: ITO SHIGENORI
IPC: H04B10/27
Filed: 1989-12-15
Abstract: PURPOSE:To miniaturize a switching part, to increase profitability and to eliminate the possibility that a signal level becomes unstable with the switching part by switching a DC bias current supplied to laser diodes through a switch and switching connections between an electronic information device and terminal devices. CONSTITUTION:The power terminals (c) or (m) DC superposing circuits N1.n-Nm.n corresponding to terminal equipment Tn are connected to the (m) fixed contacts of switch SWn, the movable contact of the switch SWn is connected to the negative electrode of a DC power source E, and the positive electrode of the power source is grounded. Then a switch SWj corresponding to a terminal Tj is changed over to connect the power source E to one of the (m) DC superposing circuits N1.j-Nm.j and the DC bias current Io is supplied to one corresponding laser diode among D1.j-Dm.j. Consequently, general small-sized, inexpensive switches for DC switching which need not have high frequency characteristics are usable and the signal level never becomes unstable owing to the loss characteristics of the switches.
