LMX6000-R

LMX6000-R Series Modem


 LMX6000-R series modems are our new R & D projects.

Model

Description

LMX6000RR

Containing single modulation transmitter and single receiver demodulator

Different suffixes in the naming of the product is used to distinguish the corresponding options, for example: LMX6000-RL

R indicates that the product is equipped with routing options, routing function;

L represents L-band modem products, if no such suffix indicates that the product is 70Mhz or 140 / 70Mhz IF modem;

T indicates that the product has been equipped with T1 / E1 G.703 interfaces;

F indicates that the product has been equipped VoIPFXS voice interface;

For standard LMX6000-R (four-channel demodulator) for all four channels share the same frequency bandwidth 36Mhz. If the optional two L-band to 70Mhz downconverter module, allows 1 & 2 channel sharing first 36Mhz bandwidth, 3 & 4 channel sharing second 36Mhz of bandwidth, so the use of a single device can cover some of the bandwidth of 72Mhz transponder frequency resource of all.
