A STEP AHEAD IN DIGITAL TELEVISION

Product made in Italy by Rover Broadcast.com

•  The ultra wide band, 47-2.700 MHz, optical, laser 

transmitter, Rover “RLT” series, equips a high 
performance, isolated and thermally-stabilized, DFB 
laser with extreme superior linearity, designed for 
high channel loading, analog/digital CATV  
and SAT signals. 

•  The “RLT” series operates at a 1550 nm wavelength, 

according to ITU-GRID, the unit is designed for 
advanced, single mode, optical, fibre networks, 
with DWDM ITU-grid (Dense Wavelength Division 
Multiplex), or CWDM grid (Coarse Wavelength 
Division Multiplex). 

•  Fine tuning (± 100 GHz) available for DWDM version, 

to enable one channel reconfiguration.

•  The unit employs superior CSO & SBS pre-correction, 

reducing laser and fiber dispersion effects. 

•  RLT Series Laser Transmitters incorporate a 

comprehensive alarm status monitoring system of 
all laser operating parameters such as: Dc laser bias 
current, laser output power, OMI, AGC status, etc.   
The USB and LAN ports provide access to the 
complete operating parameter configuration and to 
the alarm monitoring.
