Siemon explains why new short reach singlemode applications need ULL connectivity in a new white paper

Leading global network infrastructure specialist Siemon has published a new white paper that evaluates the benefits of deploying new short reach singlemode applications in the data centre and explains how ultra-low loss (ULL) fibre connectivity can support the much more stringent insertion loss requirements that these applications demand for maximum performance.

Enterprise data centres are starting to adopt singlemode fibre to support 100, 200, and 400 Gb/s speeds to distances well beyond 100 metres, gradually moving away from the long-established multimode fibre. Siemon’s white paper examines the technology advancements that have made this possible, providing an insight into the capabilities of the new data centre reach (DR) and fibre reach (FR) applications as well as the latest developments in PAM-4 signalling and newer power-conserving singlemode lasers for greater cost savings.

When deploying DR and FR applications however, data centre managers must pay attention to much more stringent insertion and return loss margins. Siemon provides an overview of the maximum channel insertion loss values, explains what to look out for when calculating loss budgets and highlights other installation variables to consider that demand additional margin.

Key focus of the discussion in the paper is ultra-low loss (ULL) fibre connectivity and how DR and FR applications can reach optimum performance when supported by ULL fibre.

The paper also provides design advice, such as deploying cross-connects for maximum flexibility, scalability and speed of deployment and the implications that cabling design can have on insertion loss values.

Finally, the paper points out the importance of third-party verification when evaluating ultra-low loss products from different vendors to ensure compliance with specific standards for safety, quality and performance and it refers to common pitfalls to avoid when selecting the right ULL product offering.
