Test and measurement equipment will be a key focus for exhibitors and delegates at ECOC 2014 in September. With many products to choose from, Robert Roe investigates how providers of test and measurement equipment stand out from the crowd
s data rates increase across fibre networks, optical loss budgets are being driven down – attenuation through the system must be lower
than ever because there is less tolerance for overall loss of light. Tis makes test and measurement (T&M)
equipment even more critical to ensuring that networks operate efficiently. A dirty connector or a kink in the fibre can disrupt services until a technician has identified the problem, physically gone to the required point in the network, and fixed the problem. And, of course, the equipment has to help ensure that all repairs are carried out as cost-effectively as possible. Sean Adam, general manager, AFL test and
inspection division, said: ‘Users of test and measurement products in the fibre optic space are faced with the competing challenges of increasing data speeds and volume, with a

demand to drive down costs. Data rates and data volume drive the requirement for more accurate measurements. At the same time, companies need to increase their staff – either through direct employment or an ever increasing use of contract labour. Tis workforce is oſten not skilled or experienced with fibre.’ Te way in which budgetary issues increase
the demands made on T&M equipment was stressed also by Paolo Magni, product marketing manager for optical T&M instruments at Yokogawa Europe T&M. He said: ‘Installers have to work within tight schedules and budget constraints given by the telecom carriers, so they have to improve the work efficiency of their technicians while adopting a wise spending policy. In addition, they have to trust the measurements taken by the instrument in order to avoid unnecessary truck rolls.’ Tis reduction in ‘truck rolls’, or the number
of times technicians are sent to fix a potential problem, is a key topic that is being addressed by many providers of test and measurement equipment. Te problem is compounded by the fact that networks will usually contain a mix of different technologies, requiring different T&M techniques.
