N optical switch routing. The design of the
VX500 is based on patented technology which enables precise fiber-to-fiber positioning of
either singlemode or multimode fibers.
Optical Switch Module
The VX500 optical switch module is an opto-mechanical switch that allows selection of an
individual fiber channel by means of a high-resolution stepper motor. The stepper motor
moves one or two common fibers into direct alignment with one or two of several output
fibers using DiCon’s patented moving fiber technology.
The VX500 is optically passive, operating independently of data rate, data format, and opti-
cal signal direction. Some of the terms used to describe the internal components of VX500
optical switch module are illustrated in Figure 1.

VX500 Interface Board
The VX500 switch module contains an electronic interface board that converts TTL input
signals to the switch's optical channel position. The important components of the interface
are labeled in Figure 2.
The twelve-pin interface connector has six data inputs (RESET and <D4:D0>) and a
STROBE input as well as two status outputs. The BUSY output indicates whether the
device is busy performing an operation or ready to receive new switching instructions. The
ERROR output indicates when an error has occurred.
The board requires a co12 VDC supply both during switching and switch hold.
