This device is a Sharplus FTTH Active Node, also known as an optical receiver, used in fiber-to-the-home networks. It converts a fiber optic signal into a standard radio frequency (RF) signal for distribution to televisions and set-top boxes via coaxial cable. 

• Function: Converts optical signals from a fiber network into RF signals for home use.
• Wavelength Range: Operates across a wide range from 1100nm to 1650nm, making it compatible with common optical transmitters and EDFA amplifiers.
• Power Supply: It requires a 12V DC power input. The design allows it to accept power through the coaxial cable (power pass system) from connected devices.
• RF Output Level: It provides a strong RF output level of up to 110dB (decibels).
• Connectivity: It features an "Optic In" port for the fiber connection and "RF Out" ports for coaxial cable connections. The model in the image is a 2-WAY splitter/node.
