ETL – NEW Ultra-Wide Dynamic Range RF over Fibre modules for HTS applications

The demand for increased signal capacity has given rise to the use of High Throughput Satellites (HTS) with wider bandwidths.

For satellite operators who need to transport HTS signals across satellite ground station sites up to 10km, fibre optic links with an ultra-wide dynamic range are of utmost importance.

Our new wide dynamic range of RF over Fibre modules provide improved RF performance with the addition of fixed gain and high linearity parameters. The fibre optic links operate with input signals from +6 dBm, down to signals just above the system noise level, making them perfect for complex wide dynamic range signal transmission.

The new fibre modules are available in L-band and Broadband frequencies for our 100 and 200 series StingRay range.

The StingRay range:

ETL’s StingRay RF over Fibre inter facility links (IFL) transmit and receive high quality RF signals over single mode fibre from, for example, a satellite antenna to reception equipment room, up to 10 km away, with options for distances up to 35 km.
COMPACT OPTIONS: We can offer a solution ultra-compact requirements or for smaller applications such as a single antenna. Our range is split in to 100 series and 200 series alternatives. The 100 series range offers up to 16 RF over Fibre links in a 1U chassis. Our 200 series range offer twin module options, where 2 separate links are provided on one module or with a -20 dB monitoring port for INPUT SIGNAL MONITORING.

Our standard 100 series and 200 series RF over Fibre modules provide AGC (Automatic Gain Control) with automatic link optimisation for FAST SET-UP or wide dynamic range links with FIXED GAIN FOR INPUT POWERS UP TO +6 dBm.

If you require ENHANCED RESILIENCE our StingRay RF over Fibre range offers 1+1 redundancy and 4+1 or 4+2 redundancy systems.
HIGH DENSITY & LONG DISTANCE OPTIONS: CWDM (coarse wavelength division multiplexing) modules provide up to 35km transmission compact fibre links, with eight wavelengths on a single fibre cable. DWDM modules (dense wavelength division multiplexing) provide up to 50km transmission fibre links, and beyond with optical amplification (EDFA), with up to forty wavelengths on a single fibre cable.
