Overview
Product description
BMS series cascadable Headend Multiswitch with redundant dual power supply in a 19″ 2RU rack-mountable enclosure.
No regular service and maintenance are needed during operation.
Optical Multiswitch System with Fiber Optic Subscriber Lines, 4 Satellites, up to 256 Subscribers with 2 TV sets each, total capacity
The new BLANKOM FTTH Fiber Optic Multiswitch System for max. 4 SAT-Positions + terrestrial RF supports the distribution of the Multiswitch SAT-IF in downstream and LNB signaling in the upstream as bidirectional direct-to-homes / wall outlets to MDU’s: SAT-FttB, FttC, FttH.
The optical Multiswitch system uses the 1550nm wavelength for the downstream of the transponder selected by the SAT receiver and the upstream of the switching data from the connected SAT receiver/tuner (transponder frequency (SAT-ZF), 13/18V=polarization, band switching low/high 0/22 kHz, SAT position DiSEqC) is transmitted at 1310 nm on the same optical fiber backwards from the BFR to the Multiswitch.
BFM-1732C Multiswitch main unit features:

BLANKOM BFR-01 Fiber Optic Receiver for 1 TV set

BLANKOM BFR-02 Fiber Optic Receiver for 2 TV sets
BFR-01/BFR -02 Optical receiver units features
Features & capabilities
Features
Fully cascadable optical multiswitch family with excellent RF performance. Up to 8 units can be cascaded.
The system can be expanded to up to 256 subscribers, with 2 TV sets each. Thus the total capacity is 512 TV sets connected to 4 satellite dishes.
All channels from 4 satellites will be accessible to each subscriber.
The cable length to each subscriber can be several kilometers long.
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.
