1u Chassis Design Standards
A rack unit (abbreviated U or RU) is a unit of measure defined as 1+3⁄4 inches (44.45 mm). It is most frequently used as a measurement of the overall height of, as well as the height of equipment that mounts in these frames, whereby the height of the frame or equipment is expressed as multiples of rack units. For example, a typical full-size rack cage is 42U high, while equipment is typically 1.

What is the function of a fiber optic terminal box in a substation
Fiber optic terminal boxes provide a structured space where technicians can neatly arrange and label fiber optic cables, connectors, and splices. They often feature cable management trays, splice holders, and adapter panels, allowing for a systematic approach to fiber optic. Fiber Termination Box, also known as FTB, typically consists of two main parts: the outer shell body and the adapter tray that protects the fiber connector points. Its function is primarily to splice, secure, and protect the optical fibers connecting the incoming drop cable to the pigtail or patch cable. Fiber optic cables, composed of ultra thin glass or plastic fibers that transmit data as light signals, are extremely fragile. The number of ports of fiber optic junction boxes ranges from 8.
