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.

ماژول SFP یکی از انواع ماژول‌ها است. برای تبدیل سیگنال دیجیتال به سیگنال نوری مورد است.فاده قرار می گیرد. این نوع ماژول می تواند مسیر انتقال اطلاعات را از طریق فیبر نوری ده ها کیلومتر افزایش دهد با این حال در حال حاضر است.فاده های زیادی دارد.

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.

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.

Both types of fiber optic cables support a speed of gigabytes, and the main difference between the two is their transmission distance. Inside data centers, multi-mode cables, which support distances of to meters, are commonly used. for make connections at long-distance, the single-mode cable can support , , km, and even more distances. All you have to do is use the right light source for the distance you want.
