FILR Series Single Link L-Band <strong>Fiber</strong> <strong>Optic</strong> Link Receiver 950-2050 MHz<br />
Blonder Tongue’s FILR series L-Band fiber optic receivers provide a cost-effective method of receiving L-Band<br />
signals for satellite receivers with the EMI immunity and superior performance inherent in fiber optic links.<br />
The FILR-S3A-2050 is a single RF output receiver that can be used for receiving LNB signals from a TVRO<br />
site at a headend facility as an alternative to the loss and slope associated with coaxial links. The FILR-S3A-<br />
2050, along with Blonder Tongue’s L-Band distribution amplifiers, optical couplers and L-Band passive devices<br />
can also be used to transport L-Band signals within MDU installations as part of a custom designed ‘singlewire’<br />
distribution system.<br />
The FILR-S3A-2050 provides full 950-2050 MHz bandwidth L-band satellite reception over a single fiber optic<br />
cable with enough RF signal level output to feed a satellite receiver or to drive several receivers by adding a<br />
Blonder Tongue distribution amplifier. These high quality links will provide excellent RFI free performance for<br />
distribution to garden style apartment complexes, and high rise buildings. Our engineers will assist you in<br />
designing your L-Band optical networks for peak performance.<br />
Special ‘stacked’ LNBFs are available to provide both satellite polarities on a single cable. The ‘single wire’<br />
system, using FILT series transmitters, can provide one fiber optic cable to feed FILR series fiber optic<br />
receivers in a headend or apartment unit. The FILR series receivers convert the incoming optical signal to a<br />
broadband RF output. In MDU applications, each output is connected to a ‘Subscriber Unit’ that responds to<br />
the satellite receiver’s tuning instructions and automatically ‘unstacks’ the polarities in order to provide seamless<br />
service to the viewer.<br />
Existing CATV or MATV channel lineups can be multiplexed onto the MDU subscriber’s coaxial cable drop outside the<br />
unit to maintain a ‘single wire’ solution for all entertainment services. Blonder Tongue also provides traditional AM/VSB<br />
fiber optic links that can distribute your CATV signals to your MDU units via fiber, creating a complete high performance<br />
optical network.<br />
Blonder Tongue’s combination of engineering expertise and versatile product line make us an ideal supplier for all your<br />
fiber optic needs. Whether you are connecting TVRO antennas to your headend, reaching new buildings from a master<br />
headend, building a brand new MDU satellite distribution system or overlaying satellite services onto an existing<br />
CATV/MATV system Blonder Tongue has the solution.<br />
