IF and L-band Routing Matrix Switch: QFM 2500

The QFM is a full fan-in RF Matrix Switch. Available in 1 RU as 8x8, 8x16, 16x8 and 16x16. The QFM can be easily expanded to a maximum system size of 32x32 by adding additional modules. The QFM features Quintech’s latest Q-ROUTE™ and Q-SENSE™ technology, which provides maximum reliability with signal path redundancy and auto re-route capabilities. The QFM is dual range with operating frequencies for IF 50 MHz - 200MHz and 950 MHz - 2150 MHz. It also offers manual gain and AGC modes with a range of -20dB to +8dB in 0.5 dB steps with individual port control to support all modulation formats. The front panel LED’s allow monitoring of power supply and alarm status information.

 


Applications:

    A Qunitech customer that operates multiple data centers had a requirement to send large amounts of data from one data center to multiple other data centers around the world. The most cost effective method of moving vast amounts of data is a satellite VSAT network. The transmit/receive modems had to be flexible in order to send and receive multiple sets of data to and from multiple locations. The customer required local and remote control capability since the data being transmitted and received constantly changed. In that the data streams were narrowband, more cost could be reduced by combining multiple data streams onto a single satellite transponder and for the global network, multiple satellites were utilized.

     

    Quintech’s QFM fan-in (combining) and QRM fan-out (splitting) matrices were perfect for providing the flexibility required. The customer could connect the transmit modems at the data center to the inputs of the QFM and flexibly combine the data streams from multiple modems to uplink to a satellite transponder. The receive data center could connect multiple satellite receive signals to the inputs of the QRM and flexibly route the satellite receive signals to multiple modems connected to customer servers
