DIRECTV® MFH2™ Single Wire Satellite Distribution System
Introduction
The DIRECTV MFH2™ System is a single-wire solution for distributing all DIRECTV Ku/Ka satellite bands from each orbital
satellite slot into a Multi-Dwelling Unit (MDU) via a single homerun wire. This technology enables a customer to receive
all of DIRECTV’s programming and services on multiple receivers inside a customer’s premise.
MFH2™ Components FMC-6 Chassis and SWM-8 module
The main technology element for MFH2™ is the eight (8) channel Single Wire Multi-switch module (SWM-8) and the six slot
FMC-6 chassis shown above. The eight channel SWM is designed to provide DIRECTV programming from all current and
future Ku/Ka satellites via a single home run wire to a set of multiple receivers connected using one or more passive
splitters inside the customer premise. The SWM-8 allocates up to eight channels for viewer selected programming for
MFH2™ compatible receivers. The FMC-6 is a six (6) slot chassis designed to house up to six (6) SWM-8 modules.
