In the IEEE 802 reference model of computer networking, the logical link control (LLC) data communication protocol layer is the upper sublayer of the data link layer (layer 2) of the seven-layer OSI model. The LLC sublayer acts as an interface between the medium access control (MAC) sublayer and the network layer.

A fiber optic connector is a mechanical device used to align and join optical fibers, enabling light to pass through with minimal loss. The fiber connector types, sometimes referred to as terminations, link fiber optic cables together through terminals, switches, adapters, and patch panels, by bridging the gap between their.

Among the component parts are metals, ceramics, thermoset and thermoplastic polymers, heat and UV cured adhesives, glasses and single-crystal Si chips. These materials are chosen on the basis of precision fabrication (submicron tolerances may be required), cost, and. Figure no 1 Fire optic cable materials "Fibre optic materials are made up of finely crafted polymers ( plastic ) or glass (silica) that are greatly translucent and allow light to pass through them with very little loss" High Transparency: Glass (silica) and plastic are highly transparent, which. According to the structure of its connector, fiber optic connectors are divided into many types, such as FC, SC, ST, LC and other types of connectors. Nearly all types of fiber optic connectors have the following components: Connector housing – Sometimes called the connector body or external housing, the housing is the largest portion of the connector and holds the ferrule.

A solid-bottom tray provides the maximum protection to cables, but requires cutting the tray or using fittings to enter or exit cables. A ventilated tray has openings in the bottom of the tray, allowing some air circulation around the cables, water drainage, and allowing some dust to fall through the tray. Q2: What fittings are used in a cable tray system? A: Common fittings include elbows, tees, crosses, reducers, and risers, which are used to change direction and create branches. Cable trays are used as an alternative to open wiring or electrical conduit systems, and are commonly used for cable management in.
