Figure 3-1. Typical Fiber Optic Cable Routing
When routed to the RU outdoor cabinet, the OSP fiber optic cable should be spliced to a
connectorized outdoor-rated cable (consisting of individual jacketed pigtails) which is then
routed into the outdoor cabinet. The individual pigtails can then be connected directly to the
STM optical ports. A connector is provided on the bottom of the RU outdoor cabinet to seal the
cable entry point and provide strain relief. The procedure for routing the fiber cable into an
outdoor cabinet and for connecting the pigtail leads to the STM is provided in the Digivance 20
Watt Outdoor Remote Unit Installation Instructions (ADCP-75-148).
When routed to RU indoor mounting shelf, the OSP cable should be terminated at a fiber
distribution panel and spliced to pigtails. Jumper patch cords may then be used to link the STM
optical ports to the OSP cable terminations. Whenever possible, a guideway such as the
FiberGuide system should be provided to protect the fiber optic patch cords from damage and to
prevent excessive bending. The procedure for connecting the OSP optical fibers to an STM
mounted in the indoor mounting shelf is provided in the Digivance 20 Watt System Indoor
Remote Unit Mounting Shelf Installation Instructions (ADCP-75-149).
