Wideband 10 MHz-3 GHz
The ViaLite Wideband RF over fiber link has a 10 MHz-3 GHz bandwidth. The link can be used to connect satellite antennas with control rooms, network operation centers or broadcast headends at both IF (70/140) and L-Band HTS. They can also be used to transport cellular, TETRA and WiMax signals into buildings, as well as HF, UHF and VHF signals.
- 50 Ohm
- Point-to-Point and Point-to-Multipoint architectures available
- WDM and CWDM options
- Transmits any RF signal – regardless of modulation scheme
- Transmission distances of 1 m to 50 km
- Interfaces with monitor and control (M&C) systems for remote monitoring
- 5-year warranty as standard

Ultra-wide dynamic range
One of the link’s key features is its ultra-wide dynamic range. This allows wider bandwidths to be transmitted including the entire 700-2450 MHz. For High Throughput Satellites (HTS), typical bandwidths are 500 and 800 MHz.
Manned from a control room
ViaLiteHD links can be controlled remotely using SNMP or Ethernet, as well as other Ethernet-controlled equipment such as the antenna, converters or amplifiers. This allows multiple antennas to be controlled over fiber from a control room.
Further features and benefits:
- Reduced spares.
In satcom, the 10 MHz-3 GHz bandwidth is compatible with both 70/140 IF and L-Band HTS signals – minimizing spares requirement.
Other link options include the ViaLite Ultra Wideband link at 2 kHz – 4.2 GHz.
The Wideband link is available in several formats:
– Single rack chassis card / Dual rack chassis card (Rx/Rx, Tx/Tx or Tx/Rx)
A fully populated 19” 3U ViaLiteHD rack chassis supports up to 26 links and accepts 13 RF cards, plus an SNMP card and dual power supply modules. A 1U chassis accepts three RF cards or two RF cards with an SNMP card.
– Blue OEM Link
The ViaLite standalone Blue OEM Link offers a compact, single link solution.
– Yellow OEM Link
The Yellow OEM Link has been designed for system integrators and equipment manufacturers to build the link into their own designs.
