• Uncalibrated tools produce unreliable measurement results that can't be certified to specifications and may violate service level agreements or ISO/TL9000 standards with your customers and their network equipment vendors.
• QoS certification may be inaccurate and generate a repeat test need. Contractors are often not compensated or could be delisted as an approved service supplier due to incorrect results.
• Full manufacturer  warranty (20-30 years) from cable suppliers (e.g. Corning, CommScope, Belden, ect.) will only be granted if the installation is certified with a calibrated instrument, thus the network owner is motivated to comply with correct installation certification procedures to retain and enforce the warranty on expensive cabling and optical network elements, etc.

Common Business impacts include:

• Lost revenue, customer complaints and increased costs: 
• Most network operators track and audit repeat work done by sub-contractors and often there is a billing dispute in these cases.  Contractors with high rates of inaccurate test results are usually hired for less or not at all when not meeting SLA agreements or quality metrics.   
• For Network Operators, repeat service quality issues with customers often causes added cost, customer dissatisfaction and loss of business.  

Example:

Let's look at OTN/SONET/SDH/E1/T1 and various FTTX, DOCIS and xDSL measurements.  It is critical to reach full line rate (1G, 10G, 40G, 100G) to test service performance and service error rates.  If the uncalibrated tester can not reach full line rate during testing, a customer may be left with suboptimal performance that will quickly create complaints or alternatively, the technician could end up chasing phantom network problems that do not exist.
