The ViaLite range of WDM, CWDM and DWDM products allow multiple channels, traveling in either direction, to be simultaneously combined over a single fiber. This means signals can be multiplexed into existing infrastructure or the number of dark fibers being leased can be reduced; lowering costs. The products come with a 5-year warranty as standard.
Wavelength division multiplexing (WDM)
- Allows 2 signals to be multiplexed
- Uni- or bi-directional
- Utilizes 1310 and 1550nm lasers
- Ideal for L-Band HTS and Reference or Tx/Rx in a single fiber, in satcom and diverse antennas within broadcast applications
- High isolation between channels (90 dB RF)
Course Wavelength Division Multiplexing (CWDM)
- 2-16 channels
- Uni- or bi-directional
- RF and data on a single strand of fiber
- Reduces the number of leased fibers required – by up to 16 times
- High isolation between channels (100 dB RF)
Dense Wavelength Division Multiplexing (DWDM)
- 2-96 channels
- Uni- or bi-directional
- RF and data on a single strand of fiber
- Reduces the number of leased fibers required – by up to 96 times
- Can be part of ViaLite’s Long Distance Link
- High isolation between channels
For complex RF over fiber systems incorporating DWDM products, we recommend the use of the ViaLite System Designer tool.
Product Inquiry
Products are available from 1310 nm/1550 nm WDM, ITU compliant 16 channel CWDM and up to 96 way ITU 50 or 100 MHz spacing DWDM compliant Multiplexers and Demultiplexers.
High-isolation variants are available which feature exceptional adjacent optical channel isolation. These are specifically designed to complement the wide-dynamic range of ViaLite‘s fiber optic links.
The WDM – 2 channel Duplexers are available in either pigtail or plug-in module format, allowing original equipment manufacturers to build them into larger systems or for them to be rack mounted in a ViaLite chassis with other modules.
The CWDM – 4 and 8 channel systems are available in compact 1U high 19″ rack format.
The DWDM – 4, 8 and 16-way systems are available in compact 1U high 19″ rack format. Up to 96 channels are available.
