Single Fashion optical fiber is a glass fiber with a diameter of . to microns (core diameter) that transmits a single wave light. The light source of single-mode mode fiber is often a laser, which makes the single-mode more expensive than multimode. Due to the smaller diameter, this type of cable is used for long distances to reduce signal loss. Single-mode fiber has more bandwidth than multimode fiber.

Multimode fiber has a diameter of about . microns and allows several light signals to pass through it simultaneously, creating several modes of diffusion or scattering. scattering limits bandwidth and transmission distance on fiber. This type of fiber has a larger diameter and supports shorter transmission distances. Multimode fiber typically uses LED to create a pulse of light, which makes it cheaper than single-mode fiber.

Fiber optic pigtails are fiber optic cables that have a connector on one end and can be connected directly to other devices and equipment through this head, and the other end, which is not connected to the connector, is usually fused. At the end of these pigtails can be used connectors of different types (for example, FC, LC…), and also these pigtails are provided in different lengths depending on the needs of users.

OCDF is used as an interface between switches with fiber optic ports and fiber optic cables. Fiber optic adapters, fiber optic cables, and fiber optic pigtails are positioned within the OCDF fiber optics. OCDF boxes play an important role in future access to fiber-optic cables and future developments. These boxes have different types, and the OCDF type is determined depending on the position and specifications of the rack and access to the fiber optic switch. What type of OCDF is used is very important. OCDFs have different types of Rackmount, Wall Mount, and Standing, each of which has different types. The fiber-optic network designer determines the OCDF type according to the location of the cable and the fiber optic switch and patch cord.
