PPC's single-stranded trunks provide the backbone connection between UHD chassis and modules in central offices. Single-stranded trunks offer a high degree of flexibility and scalability, and PPC offers these with a secondary jacket to give a higher degree of protection within cable path ways. Single-stranded trunks provide a scalable solution for users who wish to deploy 12 or 24 fibers in a single cable rather than high fiber-count multi-stranded cables. This bite-sized approach makes it easier to redeploy cables if necessary and helps to spread the costs of periodical installations. With this cable construction, you get the best of both worlds because the cable is robust and protected in the pathways yet compact and flexible inside racks and in front of equipment. PPC recommends trunk cables are configured with male connectors at each end and polarity type B. This simplifies the upgrade path to higher data rates such as 40G and 100G.
