As previously mentioned, fiber optic cables have a very small core that can be easily damaged if not protected properly. Also, to conform to the minimum size of a fiber optic loop and not violate the critical angle, we need to have a way to keep excess fiber optic patch cables, as well as terminated building fiber, neat and protected from damage. Fiber-optic enclosures and patch panels allow the cable installer to protect the delicate fiber cable from damage, while still making it useable for the network adminstrator. A commmon device that is used as a fiber-optic cable enclosure is called a Lightguide Interconnection Unit (LIU). The LIU provides a location to terminate individual fiber-optic strands into a patch panel, which will be discussed in the next section. An LIU is generally made of galvanized steel that is then power-coated to provide durability. Most major LIU manufactures make their devices 19 inches wide so they can be installed in a normal communications rack. If the LIU is to be located in an enviroment where there is a risk of moisture or corrosives, the LIU can be sealed with gaskets to make it virtually waterproof. Most LIUs have swing out trays in the front and the back to provide easy access to the patch panel located inside. Also, most LIUs provide a place to route excess cable to ensure that all loops are of a minimun diameter, so the cable will not get damaged and maximum ligth can traverse the cable.
Patch panels for fiber-optic cables are usually installed into the LIU. Because the core and cladding of two fiber optic cables that are to be joined together must match perfectly, the patch panel must be manufactured to exact specifications and some standard type connector must be used to ensure a good fit. (Fibe-opticon connectors are discussed in the next section.) Another patch panel issue deals with attenuation. Remember from the previous discussion that when you splice or join a fiber optic cable, you can introduce additional ligth loss or attenuation. The same holds ture for the fiber optic patch panel. The connectors on the patch panel should identify total loss at various wavelegths, and these losses should be added to any other cable loss on that particular cable to ensure compliance with standards and good operation of the fiber optic cable. Now we will introduce you two fiber optic patch panel in the market, they are 12 port fiber patch panel, 24 port patch panel from our store.
The 12 port fiber optic patch panel can be loaded with SC/LC/FC/ST adapters on the panel, front panel port are optional to fit simplex or duplex adapters, the fiber optic patch panel is loaded with inside trays and accessories.

Fiber optic patch panel is an integrated unit for fiber management, we offer wall mount patch panel and rack mount patch panel, these equipment function is to fix and manage the fiber optic cables inside the box as well as provide protection. There different models to fit for 12 core fiber, 24 core fiber, 36 core fiber, 48 core fiber, 72 core fiber and 96 core fiber applications. They can be with different adapter interface including the SC, ST, FC, LC MTRJ, E2000, etc.
