Intertek Testing Services , a global leader in the testing , inspection , and certification of products , tested Siemon ’ s new singlemode ultra-low-loss MTP cabling system in IEEE 802.3bs 400GBASE-DR4 and IEEE 802.3cu 400GBASE-FR4 400 Gigabit applications . The testing utilised Siemon ’ s new LightVerse fibre optic cabling system .

Both channels were configured with a higher number of connections than typically used to ensure performance across a range of deployments . The parallel optic

400GBASE-DR4 channel consisted of eight mated Siemon LightVerse MTP adapter plates and MTP-MTP cabling assemblies over the maximum allowed channel length of 500 metres .

The WDM 400GBASE-FR4 channel consisted of five Siemon LightVerse MTP-to-LC modules , MTP-MTP cabling assemblies , and LC-LC BladePatch fibre jumpers over the maximum allowed channel length of 2,000 metres . Both channel configurations were tested for insertion loss and reflectance using the one-jumper method specified in TIA- 568.3 . D standards and exhibited considerable margin over stringent IEEE channel limits .

Siemon ’ s singlemode ULL industryleading component specifications provide a maximum IL performance of 0.30 dB for MTP connectors , 0.50 dB for MTP-LC modules and 0.20 dB for LC BladePatch cords . The channel testing showed actual results well below the maximum specifications .

With emerging technologies driving widespread 400 Gigabit adoption in hyperscale data centres and enterprise data centres gearing up to deploy these nextgeneration speeds , data centre operators need to be confident that their cabling systems can reliably support current and future 400 Gigabit applications .

By demonstrating the ability of ultra-lowloss components to support multiple mated connections in 400 Gigabit channels and still meet stringent IEEE requirements , data centre operators can ensure flexibility over a range of distances and configurations , including the use of convenient cross-connects that facilitate management , upgrades , and reconfigurations – all while remaining within their loss budget .

Siemon is a vendor specialising in the design and manufacture of high quality , high-performance IT infrastructure solutions and services for datacentres , LANs , and Intelligent Buildings . With more than 400 patents specific to structured cabling , Siemon Labs invests heavily in R & D and the development of industry standards , underlining the company ’ s longstanding commitment to its customers and the industry .

“ Third-party testing of our ultra-low-loss singlemode MTP cabling system delivers that confidence and more ,” says Gary Bernstein , RCDD , CDCD , global data centre solutions specialist for Siemon . p
