Should an optical cable inside a house be run in conduit?
I am hoping to run a fibre optic cable from the office/study to the "server" room where I''ll have my NAS. The idea is to use a 10 Gbit/s connection. We are building and are currently framing.
The Ins and Outs of Optical Fiber Cable Installation
Nonconductive optical fiber cables cannot occupy a cabinet, outlet box, panel, or similar enclosure housing the electrical terminations of an electric light, power, and Class 1 circuit, unless the cable is
Duct Installation of Fiber Optic Cable
Fiber optic cable should not be coiled in a continuous direction except for lengths of 100 ft (30 m) or less. The preferred size for the figure-eight coil is about 15 ft (4.5 m) in length, with each loop 5 ft (1.5 m)
