摘要:
A network provider cable is routed to a splitter box in a multi-dwelling unit or commercial building where the cable fibers are terminated. One or more riser cables each terminate at one end at the splitter box and are routed through a building shaft. Each riser cable contains fibers associated with units located on one floor or set of adjacent floors in the building. The other end of each riser cable terminates at a first cable distribution or aggregation box located at the floor or set of floors. Each of two or more feeder cables are routed between a given aggregation box and a second cable distribution or drop box located at each floor, or at each of a number of different areas of a given floor. Drop cables are routed between each drop box and the building units on the floor or in the corresponding area of the floor. The drop boxes comprise a rotatable housing with a drum region (20) mounted on a base (12) and an interface compartment (30) located above the drum region and comprising an adaptor panel (40). The housing can be rotated with the help of a tube (60) into which a correspoinding tool can be inserted.
摘要:
Described are new cable designs for indoor installations wherein the cable comprises a dual-layer optical fiber buffer encasement of acrylate resin. The buffer encasement has an acrylate compliant inner layer that protects the fiber and minimizes stress transfer to the fiber; and a hard, tough acrylate outer layer that provides crush resistance. The dual-layer optical fiber buffer encasement is wrapped with reinforcing yarn and encased in an outer protective jacket. A dual jacket embodiment adapted for indoor/outdoor installations is also described.
