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.

Values for the optional Terrestrial-passive versions vary obviously.
Subject to change without notice! Class A might be valid only for SAT IF for some product types > 9 Inputs.
Improvements of measured values might happen during product lifecycle and might not be up-to-date in this datasheet. All Multiswitch up to 9 IN and 16 OUT are full CLASS A compliant. All models are SAT-IF Class A.
