4 LNB Feeds Over Single Fiber DWDMSatellite TV over fiber system for MDU or Municipal FTTx

distribution systems. Integrates four independent L-Band

optical DWDM transmitters with optical multiplexing filter

Combines up to four coax feeds from LNB to a single fiber

with four RF carriers on C-Band optics for use with EDFA.

Application Drawing: DWDM + EDFA = FTTx

This platform is available with multiple output power options as well as different DWDM passive and fiber options. The chassis

can be ordered without internal passives for use with an external DWDM. Thor provides full system design and integration

services for any scale system. This platform can also work with GPON or AE systems to provide internet and telephone

service in addition to Satellite TV over a single fiber. When used with EDFA optical amplifiers and PLC splitters, this transmitter

can deliver service to up to 512 optical receivers. For systems requiring more subscribers, Thor offers externally modulated

systems by request. Alternately, multiple transmitters can be used. All configuration settings are power levels can be

managed through the web interface, and SNMP is available. Rear panel switches are used to set polarity tone and LNB power.

4 LNB Feeds Over Single Fiber DWDM

Thor Integrated DWDM receivers combine optical filters

with 4 discrete L-Band outputs. These subscriber units

can be customized for any optical channels or signal types.

In addition to L-Band, cable TV RF (45-900MHz) can also

be added as an option. By incorporating the DWDM

seperation filter into the chassis, only one fiber is needed

to carry all necessary satellite sources and polarities. RF

outputs are provided on standard 75 Ohm Type-F

connectors. This system is designed to connect directly to The customer premise equipment, such as an MDU distributor or single wire multiswitch. This platforms low cost point makes it

useful for both large MDU installations as well as municipal scale fiber to the home deployments. Suitable for long fiber runs,

Thor RF receivers have high sensitivity diodes that function down to -12 dBm optical power level. This high sensitivity allows

longer fiber runs with more splits and splices. In addition, the use of C-Band DWDM optics allows for EDFA in line

amplification. Thor DWDM L-Band systems are designed for large installations requiring scalability. Additional EDFA

amplifiers can be added at any time to increase subscriber capacity without requiring a substantial expense. Thor provides

complete solutions for all FTTx applications, and offers on site optical engineering service, 24/7 support, and 5 years warranty.
