Technical data on MRT - optical return path transmitter modules
MRT
• optical return path transmitter modules features test point, pilot tone option
(AO 801V1 only), SC/APC or E2000 optical connectors.
MCA 100
• automatic gain control features - requires only one pilot frequency, any tone
or signal can be used as pilot, very easy alignment procedure, allows for
compensation for seasonal temperatures prior to adjustment
• Automatic “shift to manual” function
