No-Compromise Versatility for Metro and Long-Haul Testing

Today’s fiber networks integrate long-haul and metro applications, making OTDR versatility a must. While long-haul architectures require high dynamic range values to reach greater distances, metro links demand an OTDR delivering good resolution (short dead zones) due to the proximity of many connection points. Up to now, OTDR users had to compromise on one or the other and buy two units—a choice that they no longer have to make.
