ViaLite Expands L-band Range for HTS RF Over Fiber Products

[Via Satellite 08-12-2016] ViaLite Communications has widened the bandwidth of its L-band Radio Frequency (RF) over fiber links from the 950 to 2150MHz range to 700 to 2450MHz. The new “L-band HTS” frequency range is wider than the company’s previous extended L-band range, allowing more High Throughput Satellite (HTS) signals to be sent over a single fiber.

ViaLite has found that high throughput satellites, which have transponder bandwidths of 500 or 800MHz, compared to the 36MHz of traditional satellites, have increased the importance of dynamic range. With the L-band HTS bandwidth range of 700 to 24050MHz, either 3x500MHz or 2x800MHz signals can be transferred over a single fiber link, reducing the number of links required — and therefore costs — by a third, according to the company.

The new HTS bandwidth applies to 10 products including: L-band HTS, Long distance Dense Wavelength Division Multiplexing (DWDM) systems, L-Band HTS with combined reference, and Coarse Wavelength Division Multiplexing (CWDM) multi-channels in a single fiber — all in 50 and 75 ohm. ViaLite also offers a five-year product warranty as standard across all products.
