Romex is a brand name for non-metallic paper bonded cable (NM-B, as printed on the jacket) with a PVC jacket. This is why type UF is suitable for burying and wet locations (or dry) where NM-B cable is suitable only for very specific dry locations.
No, you can not run your Romex wiring in conduits.
Low-voltage (no more than 30 volts) wiring must be buried at least 6 inches deep. Buried wiring runs that transition from underground to above ground must be protected in conduit from the required cover depth or 18 inches to its termination point above ground, or at least 8 feet above grade.
Polyethylene PETypically used as a jacket material for Outside Plant fiber optic cables.
Commscope's Fiber Optic Splice Closure (FOSC) series is the industry leading outside plant fiber protection closure family. Whether you prefer the heat-shrink seal technology of the FOSC 400, or the gel block sealing of the 450 and 600 series, these closures have stand the test of time.
The fiber optic closure connects and stores optical fibers safely either in the outside plant or indoor buildings. It can provide protection for the fiber joint and the fiber cables since they have excellent mechanical strength and strong out shell, which ensures the joints are not damaged by the hostile environment.
Ribbon cable is preferred where high fiber counts and small diameter cables are needed. This cable has the most fibers in the smallest cable, since all the fibers are laid out in rows in ribbons, typically of 12 fibers, and the ribbons are laid on top of each other.
ONT (Optical Network Termination), also called ONU (Optical Network Unit), refer to the consumer end equipment in an optical Fiber to the Home (FTTH) link.
The ONT (also called the modem) connects to the Termination Point (TP) with an optical fibre cable. It connects to your router via a LAN / ethernet cable and translates light signals from the fibre optic line from your TP into electronic signals that your router can read.
One of the toughest roadblocks to bringing high speed broadband to rural counties is the cost of installing fiber optic cable. The Department of Transportation has compiled statistics that put the average cost of laying fiber at $27,000 per mile.fiber optic enclosures
