L-band Matrix - Combining (Fan-in)
ETL has a broad L-band Switch Matrix and L-band Router range for Satellite communications, including the hot-swap NiGMa L-band Matrix which is used for many high resilience high performance applications and smaller more application-specific L-band Routers which are used in cruise ships, broadcast relay stations, and smaller broadcast functions.
The architecture of all of these smaller L-band Matrix products is very similar, but the 2U and 3U units are generally not hot swap. All of the range has input switch cards and output combiner cards, dual redundant PSU's and a CPU. There is a variety of L-band matrix local control panels, defined by customer requirements. Remote control is via serial or ethernet ports in general.
The 16x16 modules can be linked together to form larger systems such as 32x16 matrices.
