SHF Matrix / SHF Router
ETL has a broad SHF Switch Matrix and SHF Router range for Satellite communications, including the hot-swap NiGMa SHF Matrix which is used for many high resilience high performance applications and smaller more application-specific SHF Routers which are used in cruise ships, broadcast relay stations, and smaller broadcast functions.
The architecture of all of these smaller SHF Matrix products are very similar, but the 2U, 3U and 4U, units are generally not hot swap. All of the range has input splitter cards and output switch cards, dual redundant PSU's and a CPU. There is a variety of SHF Matrix local control panels, defined by customer requirements. Remote control is via serial or ethernet ports in general.
Some of the SHF Routers have hot swap power supplies.
The 16x16 modules can be linked together to form larger systems such as 16x32 or 32x16 matrices.
Non-blocking: Any input can be routed to any output.
In general our solid state (L-band) matrices are non-blocking.
Full Fan-out Matrix (or fully distributive or splitting matrix): any input can be routed to any output. One input can be routed to many outputs. Each output can only have one input. Tends to be more RX.
Full Fan-in Matrix (or fully combining matrix): any input can be routed to any output. Many inputs can be routed to each output. Each input can only be routed to one output. Tends to be more TX.
Fan-in Fan-out (FIFO) Matrix: multiple inputs can be combined and the combined signal can then be routed (distributed) to multiple outputs. There is no restriction on how many inputs and outputs can be connected together simultaneously, even all inputs to all outputs at once.
