The Allied Telesis AT-SPSX multimode SFP fiber module is a connectivity component designed to deliver reliable performance in high-speed networks through wired transmission technology. This module is built to operate at a data transfer rate of 1250 Mbit/s, ideal for environments requiring a steady and efficient flow of information. It uses an 850 nm wavelength, typical of multimode fiber, allowing it to reach a maximum transfer distance of up to 550 meters, sufficient to cover network links in enterprise or campus infrastructures. Its LC-type interface ensures a standard connection compatible with most network equipment using multimode fiber. Additionally, the module features a receiver sensitivity of -30 dBmW, helping maintain signal integrity in environments with possible interference or minimal signal loss. It is designed to plug into EU ports, ensuring easy integration into existing network infrastructure. Thanks to its technical specifications, the AT-SPSX provides an efficient and robust solution to extend or maintain multimode fiber optic links, avoiding common limitations in short- and medium-range transmissions. This module is a suitable choice for installations demanding reliability, compatibility, and stable performance in professional fiber optic connections.
