This device is a Sharp Vision AS 795 FTTB DC Node, a critical component in fiber-to-the-building (FTTB) networks. It essentially acts as a translator, converting optical signals from a fiber cable into electrical RF signals for distribution via coaxial cables.
Here is a breakdown of the technical specifications and ports shown on the unit:
Technical Specifications
-
Optical Input Range: Operates between 1100nm to 1650nm, covering standard CATV and data wavelengths.
-
Output Level: Indicates a high output capability of 100dB (likely $dB\mu V$), suitable for driving signals to multiple subscribers.
-
Power Requirements: Operates on 12V DC. It specifically notes it can run on 12V PSP (Power Supply Port).
Connection Ports & Controls
-
OPT IN: The green port at the top is the SC/APC optical input where the main fiber line connects.
-
OUT 1 & OUT 2: Two RF output ports at the bottom for connecting coaxial cables to distribute the TV/Internet signal.
-
12VDC: The power input socket.
-
GAIN: A variable control (adjustment screw) to manually increase or decrease the signal strength.
-
Indicator LEDs (G/R): * Green (OK): Indicates the optical input power is within the correct operating range.
-
Red (LOW): Indicates the optical signal is too weak, which may cause tiling or loss of service.
