The device shown is a Sharp Vision AS 773 WDM Passive Node, a specialized component used in Fiber-to-the-Home (FTTH) and Cable TV (CATV) networks to split internet and television signals.
Key Specifications
- Function: It separates optical signals into internet data and television signals using WDM (Wavelength Division Multiplexing) technology.
-
Wavelengths:
- COM IN (1310/1490/1550 nm): Accepts a single fiber input containing all three wavelengths.
- PON OUT (1310/1490 nm): Passes through data signals for the internet router (ONU/ONT).
- RF OUT (1550 nm): Converts the 1550 nm video wavelength into a radio frequency (RF) signal for your TV.
- Passive Operation: It is "passive" because it typically requires no external power supply for the optical-to-RF conversion, though some models mention 12V support for specific features like amplification.
- Output Level: Features a 70 dB output level, indicating the strength of the RF signal sent to the TV
