Reducing the Structured Cable Footprint

As part of our continual improvement initiative CCI has migrated from the standard Microcore® or Nanocore® loose tube style trunk cable to a new smaller sub-unitized cable design. Believe it or not this new 2mm sub-unitized design not only reduces the overall cable diameters as shown below but it also performed better in many of the qualification tests due to its solid construction.

The use of the MTP connecters in Structured cabling solutions has been steadily increasing and when terminating the standard loose tube style cable the fibers must be separated, inserted into 3mm furcation tubing or sheathing, and then this sheathing must be attached to the main trunk strength member into a furcation pod to ensure proper reliability and pull strengths. This is a very time consuming process and can lend itself to many issues including varying pull strengths, broken fibers and in the case of high fiber count cables a rather large furcation region.

Aside from the obvious manufacturing benefits of this new design there are also advantages to the installers and project managers including reducing the overall cost of the project through reduce manufacturing costs, increasing airflow within the data center raceways and cabinets by reducing the overall trunk size and the breakout diameters by 33%, and also increasing the robustness and reliability by eliminating the cable furcation points.

This new trunk cable design is offered in all flavors including, singlemode OS1 and OS2 or multimode OM1, OM2, OM3, and OM4 glass with Low Smoke Zero Halogen, Riser or Plenum rated jacketing to choose from. By design MTP or MPO connector terminations are ideal but with the same sheathing and furcation’s previously used on loose tube cable all other terminations are easily supported included LC, SC, MTRJ and ST connectors.
