L-band Router Fan-in 32 x 32 NGMC-21: 32 inputs x 32 outputs fan-in hot-swap NiGMa L-band Router

At ETL an L-band Router is known as an L-band Matrix. We are aware that many of our customers use the term L-band Router and therefore to view our full range of L-band Routers and L-band Matrices please visit our L-band Matrix page.

ETL has a broad L-band Router and L-band Matrix range for Satellite communications, including the hot-swap NiGMa L-band Router which is used for many high resilience high performance applications.

Now in its 3rd generation, the NiGMa L-band Router has proved to be genuinely high performance with excellent flatness or frequency response, excellent isolation, and linearity - a truly leading edge L-band Router.

The NiGMa L-band Router has hot swap of all active components - RF cards, CPU's and PSU's. In addition the NiGMa L-band Router has the designed-in resilience provided by one RF card for each RF input and output, dual redundant CPU's, and dual redundant PSU's.

The NiGMa L-band Router also has extensive on-board monitoring - and reporting - of RF card amplifier status, CPU and PSU status and HMI communications.

The NiGMa L-band Router can easily be formed into larger router Systems up to 512x512.

Non-blocking: this means 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.

L-band signal routing evolves to new heights

ETL’s popular high performance NiGMa L-band combining matrix evolves to set new benchmarks for RF performance and leading edge technologies.
The next generation of NiGMa matrix focuses on improved resilience and performance the impact of failure is minimised

As ETL customers use matrices in mission-critical applications, we understand the importance of redundancy and hot swap. Input and output cards, power supplies, CPU controller cards, fans and the new VGA human interface can all be hot swapped. New Matrix design means there is one card associated with each input and each output – so failure of a card only affects one channel. For broadcasters, satellite operators and the defence sector, this provides exceptional resilience. The refined design offers rugged dual redundant power supplies with simple front access, enhanced CPU change-out, hot-swap fans and new card connectors. Web Browser Interface is standard on an NGMC-21.
Improved RF performance of the NiGMa which provides superior Isolation, frequency response or flatness, and 1 dB GCP levels – helping our customers ensure that their o v e r a l l R F c h a i n s i g n a l p e r f o r m a n c e i s o p t i m i s e d .
Self Diagnostics with continuous monitoring (and reporting) of amplifier status, PSU status (including temperature), fan speed and internal communications is included as standard. Any problems are rapidly identified and hot swap means they can be addressed in minutes.
