SMATV & Multiswitches
BMS-1732K
19" Multiswitch for 2 or 4x SAT + Terrestrial, 32 Outputs
Distribute up to 4 SAT positions plus terrestrial signals to 32 receiver outputs with a cascadable 19" rack multiswitch — engineered for reliable, low-loss distribution in demanding SMATV head-ends.
Overview
The BMS-1732K is a professional 19" 2 RU rack-mount multiswitch for up to 4 SAT positions plus terrestrial, fed from standard Quattro LNBs or from optic-electric converters such as the BFR-41 via CWDM fibre. It distributes up to 32 RF outputs to head-end receivers and supports up to 8 consecutive cascades via loop-through. Dual redundant industrial power supplies, sharp lossless filtering per subscriber output (950-2150 MHz SAT, 47-870 MHz terrestrial) and an RF design optimized for DVB IPTV and digital head-ends ensure dependable operation. A 2-SAT-position variant (BMS-0932K) and a standalone S version are also available.
