  • Page 9: Introduction

    ANT-20SE Optical Interfaces Introduction Glass optical fibers are generally used as the transmission medium for SDH, SONET and ATM networks. Increasing integration has meant that the optical line equipment forms part of the network elements. The test equipment used for testing these elements must therefore be fitted with optical interfaces.
