(35) A connection link 221 extends between the first MOCA only input/output port 203 and the second MOCA only input/output port 203A. As illustrated in
(36)
(37) For example,
(38) A MoCA only input/output port 203 is located on the exterior of the housing 322. A MoCA signal path 328 within the housing 322 connects the power divider network 170-B to the MoCA only input/output port 203. A MoCA pass filter 207 is placed within the housing 322 and located along the MoCA signal path 328. The MoCA pass filter 207 has a first node 209 connected to the power divider network 170-B and a second node 330 connected to the MoCA only input/output port 203. In
(39)
(40) A MoCA only input/output port 203 is located on the exterior of the housing 362. A MoCA signal path 368 within the housing 362 connects the power divider network 170-C to the MoCA only input/output port 203.

(43) However, the first node 209 may be connected to other locations within the power divider network 170-C, such as the dashed box locations 219 illustrated in
(44) In
(45) Now with reference to
(46) In the above method, attaching the RF signal feed 10 from the service provider 10 to the first and second RF input ports 105 and 105A of the first and second bi-directional RF signal amplifiers 200 and 200A may include providing a signal splitter 40. The technician attaches the RF signal feed 20 from the service provider 10 to an input 30 of the signal splitter 40. Then, the technician attaches first and second outputs 50 and 60 of the signal splitter 40 to the first and second RF input ports 105 and 105A of the first and second bi-directional RF signal amplifiers 200 and 200A, respectively.
(47) As used herein, a MoCA pass filter may be a high pass filter which significantly attenuates or blocks the upstream and downstream communications between the service provider and customer devices, and passes frequencies above the upstream and downstream communications between the service provider and customer devices with relatively little to no attenuation. Alternatively, the MoCA pass filter may be a notch filter which functions the same as above but also significantly attenuates frequencies above the MoCA frequencies. Blocking frequencies above the MoCA frequency band can be beneficial in reducing noise issues in the system. Noise can occur from such household sources as cordless phones, cell phones, wireless alarm system sensors and cameras, WiFi routers and repeaters, connected WiFi devices, etc.
(48) The MoCA pass filter may be designed to pass frequencies in a range of 850 MHz to 1,675 MHz and to attenuate frequencies below and/or above the range. However, sometimes service providers will provide entertainment and information services and/or receive customer data in a bandwidth extending up to or exceeding about 1,000 MHz. Therefore, in another embodiment, the MoCA pass filter passes frequencies in a range of 1,125 MHz to 1,675 MHz and attenuates frequencies below and/or above the range. In either embodiment, the MoCA filter is intended to allow MoCA band frequencies to pass freely therethrough in both directions.
(49) The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are to be included within the scope of the following claims.
