This is a Sharp Plus FTTH (Fiber to the Home) Active Node, which is a type of optical receiver used in fiber optic networks.
- Function: It converts the incoming optical signal from a fiber optic cable into an RF (radio frequency) signal for use with standard coaxial cable systems like cable TV.
- Input: It accepts an optical input signal in the 1100nm to 1650nm wavelength range via an SC/APC optical connector.
- Output: It provides an RF output via a coaxial F-connector.
- Power: It requires a 12V DC power input.
- Gain: It offers a gain of 100dB.
Key Features and Function
- Function: This node is designed to bring fiber optic services, such as high-definition TV and high-speed internet, directly to a home or apartment building. It typically uses GaAs amplifier technology to ensure a low-noise, high-quality signal for multiple televisions.
- Wavelength: It operates in a wide wavelength range, from 1100nm to 1650nm, making it compatible with both 1310nm and 1550nm optical network signals.
- Power: As an "active node," it requires external power, typically 12V DC input, which can be supplied via a separate adapter or sometimes even over the same coaxial cable (Power over Coax or PoC).
- Gain & Output: The device features a high gain of up to 100dB, with an RF output level of around 110dBµV, to drive signals across internal coaxial wiring.
- Connections: It has an "Optic In" port for the fiber cable (likely SC/APC connector type, as implied by similar products) and an "RF Out" coaxial port to connect to a TV or internal network.
