The FILT S3A-3000 L-Band fiber optic transmitters and FILR S4A-3000 receivers provide a costeffective method of transporting L-Band signals to satellite receivers with the EMI immunity and superior performance inherent in fiber optic links. A typical application would be to transport LNB signals from a remote TVRO site to the headend facility as an alternative to coaxial distribution avoiding its associated high loss and slope. The FILT/FILR, along with Blonder Tongue's L-Band distribution amplifiers, optical couplers and L-Band passive devices can also be used in distributing L-Band signals within MDU's.

The FILT-S3A-2050- 12 and 16 series of fiber optic transmitters allow the operator to distribute DTH/DBS signals from a single satellite dish to multiple locations via single mode fiber. The transmitter is available in 12 and 16 output versions to accommodate a variety of MDU topologies. The unit features automatic gain control (AGC) on the satellite input to help ensure optimum input levels with changes in weather. The transmitter is equipped with two LED indicators, one for power on (green) and the other for a low RF input alarm (red). For remote monitoring, a TTL based alarm monitor is provided on the rear panel. The alarm will trigger with either a low RF input; optical or DC failure. An alarm condition results in the monitor output going low (0 VDC). Under normal operating conditions the monitor output is 5 VDC. Both versions of the transmitters are in a single height, 1.75" high, 19" rack mount aluminum chassis for easy installation into any headend. Switched LNB power is multiplexed on the RF input connector, eliminating the need for external power inserters.

The FILN multi-output L-band receiver is a breakthrough in hybrid fiber/coax (HFC) optical node technology. The unit combines the superior distribution attributes of several key functions into a single package. These are:

• Satellite signal fiber receiver
• Professional quality L-band amplifier
• Bi-directional CATV network amplifier employing trunk line grade hybrid amplifier modules
• Plug-in equalizers and attenuators for greater CATV input signal management, creating design flexibility
• CATV and satellite signal multiplexing and splitting networks with up to 24 residential outputs
• Return path management and amplification (10-40 MHz)

The unit provides L-band DTH signal for up to 24 residential outputs, from one fiber input. There is an LED indicator on the optical input of the unit to indicate proper input level. There is also an LED on the L-band output to indicate the optimum output level. High L-Band signal levels are provided to each output to overcome the loss of long drop lengths and premise splitters required to serve multiple subscriber viewing locations. CATV Network Amplifier Section The unit accommodates a wide range of CATV input levels, making it more forgiving to existing CATV conditions and allowing for greater design flexibility. This is accomplished by the use of plug-in attenuators and equalizers to condition the input signal prior to amplification and splitting. The network amplifier is designed to handle both analog and digital channels in the bandwidth of 54-750 MHz. Additionally, the CATV amplifier has a return bandwidth of 10-40 MHz for compatibility with PPV, VOD, telephone and high speed data CATV services. The FILN multiplexes the bi-directional CATV signals with the satellite signals at each of the either 8,16 or 24 outputs depending on the model deployed, thus creating a "True Single Wire" distribution solution.
