BMS series cascadable Headend Multiswitch with redundant dual power supply, in 19″ rack mountable enclosure.
BMS series cascadable Headend Multiswitch with redundant dual power supply, in 19″ rack mountable enclosure.
Features
Fully cascadable multiswitch family with excellent RF performance.
Optimized for 7/24 use in headend environment. 19″ rack mountable enclosure. Redundant power supply with permanent load balancing.
Active terrestrial input enables UWB (ultra wide band) distribution of DVB-C/C2 and DVB-T/T2 signals together with SAT-IF.
Application
Multiswitch optimized for use in DVB and IPTV headends.
Can feed headend equipment with SAT-IF signals of different satellites or can directly feed satellite receivers of housholds with IF+RF signals combined.
