Fiber amplifiers are devices used in optical fiber networks to boost (amplify) light signals directly—without needing to convert them to electrical signals first. This allows the signal to travel longer distances through the fiber without degrading.

Load coils, also known as loading coils, are inductors used in electronic circuits to increase inductance. They were initially used in the 19th century to prevent signal distortion in long-distance telegraph cables. In modern applications, they are also used in radio antennas and telephone lines.

Fiber Repeaters are used to extend and repeat Ethernet data signals over multimode or single mode fiber up to 160km [100 miles]. If you need to convert Single Mode to Multimode, or extend a Multimode network, Fiber Optic Repeaters are the devices to use. They are the ideal solution to connect different fiber types, distances and wavelengths (WDM, CWDM & DWDM) across a variety of topologies and network architectures for longer data transmission distances.

Coax amplifiers, also known as RF amplifiers or signal boosters, are devices used in coaxial cable networks (like those used for cable TV and internet) to strengthen radio frequency (RF) signals that weaken over distance. They can boost signal strength to prevent signal loss (attenuation) over long cable runs, help maintain signal quality for TV, internet, or other RF-based services, and ensure proper levels for multiple devices (TVs, modems, set-top boxes) when signal is split.
