ITU Sets New Fiber Standards

GENEVA -- ITU has completed work that smooths the way for a vital component of next generation networks. The new set of performance measurements will make it easier for service providers to deploy Sealed Fibre Optics and Passive node elements in next generation fibre optic networks. It will also mean that manufacturers will be able to speed-up their development cycles, resulting in lower prices. The standards give special attention to network stability and future adaptability, key concerns for all telecom operators.

The standards known as ITU-T Recommendations L.13 and L.51 form the first international performance standards for fiber optic closures in the world. A fibre optic closure is equipment that protects fibre optic components from the elements. The standards will allow network operators to more accurately benchmark optical node products. Manufacturers will find conformance testing simplified and the process of tendering and ordering easier, as the standards can be specified in tenders.

The globally applicable standards were conceived as a practical tool for generating performance specifications for sealed optical closures in outside plant, in response to industry demand. A complete basic test plan, together with summary checklist, make them the ultimate tool for anyone involved in the development and purchasing of optical closures.

"In the past, several attempts were made to develop an internationally acceptable performance standard for optical closures, without success. ITU-T Study Group 6 leveraging the knowledge and years of experience of member operators and manufacturers around the globe is the first organization to do so. We also have to thank the International Electrotechnical Commission (IEC) for their close cooperation," says Francesco Montalti, President of Study Group 6.

The use of Recommendations L.13 and L.51 in the deployment of optical networks will provide a more consistent level of quality resulting in more stable and future proof networks. Ultimately this will help maintain the standards of quality needed by the most recent transmission equipment and reduce outages at passive nodes.
