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.

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.

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.

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.

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.
