It works over single-mode fiber for up to 40km. This makes it good for long network connections. These help keep signals strong. The module works with many Cisco and other brands'. Fiber optic cables can be run anywhere from 2 kilometers to over 100 kilometers without signal regeneration, depending on the cable type and application. The most common SFP types include SX (short-range) and LX (long-range), with the main distinction being the wavelength: SX typically operates at 850 nm (used for shorter distances). Fiber optic cables have revolutionized modern communication networks by enabling blazing-fast data transmission across vast distances. As network architects push the boundaries of what's possible, understanding the practical factors limiting transmission. First is the attenuation of the optical fiber.
