sat-nms L-Band Switch Matrix LSM
The sat-nms LSM L-Band Switch Matrix with optional fibre optical interfaces is a central sub-system in a satellite ground station or a teleport with several antennas. The switch matrix allows the user to switch each of its RF inputs, for example from different antennas/LNCs, to each output, actively distributed, without any blocking effects. This gives the user an unlimited routing and configuration capability.
New compared to other system designs is that the switch matrix has not only coaxial input and outputs but also provides mono mode fibre optical interfaces. The user is in a position to mix optical and RF interfaces easily. Details about the optical link modules are here .
The optical link is the interface to the LNC at the different antennas and transfers the signals via fiber optic even over long distances (which cannot be handled by coaxial cable) to the optical input ports of the switch matrix.
The unit includes two power supplies with two independent mains voltage input connectors. Internal redundancy switchover between the two power supplies improves the availability of the unit. All modules are hot swappable without interrupting the users services.
Model variants
The switch matrix is available in a lot of different configurations. The number of input and outputs are the maximum possible number for the model. Subsets are also possible e.g. the LSM 1012 is a 16x16 matrix equipped with 10 Input cards and 12 output cards which can be expanded with up to 16 input and 16 outputs.
The modular design allows also larger numbers of input and output ports. Matrix systems which are bigger than 32x32 will be done by a combination of n x 32x32 complete matrices..
