Fiber Optics Testing

NTS is equipped to test optical fiber, cable and active/passive components and systems. At NTS we test against a variety of specifications including Telcordia, Military, TIA/EIA, and ISO. We also perform customized test programs against specifications or test plans developed with or for our customers. Our in-house Subject Matter Experts (SMEs) can also help develop and present customized training programs to address a variety of our customer's needs. Testing is not our only area of expertise; our Consulting Services are available to assist manufacturers in designing, troubleshooting, and delivering a quality product to market. Our goal is simple: to help our clients make the most efficient use of their products in their systems, network designs and deployments.

NTS has invested heavily in optical equipment - our overall chamber capacity is one of the largest in North America. We have recently tripled our switch capacity by adding new high channel count JDS and EXFO switches which allows us to run multiple single mode and multi-mode programs simultaneously. Our lab is outfitted to make spectral measurements using tunable lasers, OSAs, white light sources and monochromator based systems.

Our expertise covers the ability to make measurements of insertion loss, reflectance, PDL, PMD, ASE noise, amplification, BER, dispersion penalty, temperature effect, bandwidth, optical band pass and others. We have performed tests in both laboratory and field environments. Additionally, we have developed requirements, training procedures, and standard operating procedures for both the telco and CATV markets. Our knowledge of the industry standards and relationships throughout the marketplace sets NTS apart from our competition.
