BMS series cascadable Headend Multiswitch with redundant dual power supply, in 19″ rack mountable enclosure.

Features

BLANKOM BRS-0512C is a high-performance 1x SatPosition Gateway device for digital TV broadcasting headend systems with a high end performance.

Designed for the modern 19’’ rack mounting installations. This professional Multiswitch can be cascaded and is useful to grow with your demands. If more Receiver outputs are needed – simply add a second device in your 19’’ Rack. (Up to 8 cascading devices in one chain are possible)

The LNB power can be set to ON or OFF to be almost flexible for the combination  with non-powered devices like fibre optic LNB or similar optical transmitter – receiver couples like the BLANKOM BFT-44 (4x fibre transmitter) to BFR-44 /4x (Fibre receiver).

LED’s are showing the actual status as well as Gain adjustments for the 4 SATlevels are securing a flexible installation even with multiple LNB supporting.

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.

Application Example:

IPTV Headend with BLANKOM Multiswitches

Capacity: 2048 TV channels from 64 Transponders in 4 Satellites and from local DVB-T/T2 antenna

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.
