DWDM Multiplexer & Demultiplexer | Series 33000
Dense Wavelength-Division Multiplexer (DWDM) can combine up to 80 fiber outputs from Global Foxcom’s fiber optic transmitters into one single fiber (RFoF). Each transmission is on a different optical wavelength. DWDM technology uses ITU standard 1.6nm spacing between wavelengths. Each wavelength is transmitted on a separate single mode fiber optic cable and then multiplexed onto a single fiber. Global Foxcom’s Dense Wavelength Division De-multiplexer reverses the process, separating light into 16 separate fiber paths.
With Global Foxcom’s DWDM solution, transmitting multiple L-Band and 70/140 IF Band signals over a single fiber becomes a simple and cost effective process. DWDM overcomes the need for installing new fiber or leasing cables. By using Global Foxcom’s DWDM solution, long distance transmission can be achieved.
Features & Benefits
- Multiplexes up to 80 RF 5-3000MHz RF channels
- Reduced cost of leasing or laying fiber
- Thin film filter technology provides reliable and cost-effective performance
- Protocol transparent
