RETURN FREQUENCY MULTIPLIERS
The Laser Plus system includes 3 receiver/ down converter modules that can be used as part of a return
band frequency multiplier system. This system can quadruple the bandwidth of a new or existing return link. Olson
Technology builds up converters to fit inside the nodes of several manufacturers. Consult the factory for the latest
list of compatible nodes.
See the LPDC-212 / LPDC-234 instruction manual, OT # 025-370447, for more details.
