Our passive components (SC4W and TRI-SC4W) provide RF distribution and filtering.
Due to the flexible design of Sirius, the same passive components can be used for different purposes, making a wide range of Coverage System configuration options available, single operator (single band / multi-band) and multi-operator (single-band / multi-band).

A single 4-way Combiner/Splitter (SC4W) can be used to manage either:
• up to 4 RF interface modules, operating in the same band (Multi-Operator Systems) or
• up to 4 Fiber Optic Transmitter/Receiver Modules - i.e. up to 16 Remote Units or
• up to 4 Master Point to Point Modules - i.e. up to 64 Remote Units.

The Triplexer with built-in 1:4 Splitter/Combiner (TRI-SC4W) is used in multi-band configurations to distribute signals operating over different bands. The module also includes a 4-way Splitter/Combiner to drive up to 4 Optical Modules.

The Triplexer is able to manage up to 4 Fiber Optic Transmitter/Receiver Modules- i.e. up to 16 Remote Units or up to 4 Master Point to Point Modules- i.e. up to 64 Remote Units and:
• up to 3 RF interface modules, operating in different bands, or
• up to 3 Service Front Ends, operating in different bands, or
• up to 3 four-way splitter/combiner modules (SC4W), each connected to multiple RF interface modules operating in the same band.

Several models of Triplexers, operating over different Uplink/Downlink frequency bands, are available.
