DWDM Multiplexer & Demultiplexer | Series 33000
The Series 33000 DWDM Multiplexer & Demultiplexer from Global Foxcom enables multiple optical transmissions to share one fiber path for RF over Fiber applications. It is designed for efficient transport of L-Band and 70/140 MHz IF Band signals.
Features & Benefits
- Multiplexes up to 80 RF channels
- Supports RF frequencies from 5 to 3000 MHz
- Reduces the need for additional fiber installation or cable leasing
- Uses ITU-standard wavelength spacing
- Thin film filter technology for reliable optical performance
- Protocol-transparent operation
- Supports long-distance RF signal transmission
Basic Details
Dense Wavelength-Division Multiplexer (DWDM) uses different optical wavelengths to carry separate transmissions through a shared RF over Fiber path. DWDM technology uses ITU-standard 1.6 nm spacing between wavelengths, with each wavelength transmitted on a separate single-mode fiber optic cable before being multiplexed onto one fiber. Global Foxcom’s Dense Wavelength Division demultiplexer reverses the process by separating the light into 16 separate fiber paths.
