The RedLink+ FLCRplus Series in 1RU or 3RU/19" design represents an efficient rack-mount RF-over-Fiber chassis for insertion of optical transmitter or receiver modules supporting versatile redundant optical transmission configurations. It is designed for flexible, high quality and absolute secure optical transmission for 1...16 signals ( L-Band, IF* or 10MHz*) over a distance of up to 10km featuring various redundant optical configurations such as N+1 or N+2 (pls. refer to below table). The RedLink+ FLCRplus is availabe in 1RU/19" and 3RU/19" rack-mount design and can be equipped from 1 -16 optical modules (TX/RX) and up to 4 hot-standby modules (TX/RX) for different redundant operations (N+1 or N+2) while also mixed TX/RX configuration per group is possible with the corresponding chassis-variants. The system is scalable and expandable from non-redundant to reduntant operation. The redundancy switching can be realized and configured locally (LC-D touchscreen) but also remotely via the Ethernet-Interface (WebGUI/SNMP). The RedLink+ FLCRplus system features automatic redundancy switching as per preconfigured configurations. Once an error for an TX or RX module happens an SNMP-message will be sent out to the other chassis and the switch-over to the hot-standby redundant module will be done automatically assuring interruption free signal transmission. The RedLink+ FLCRplus chassis support 1:1 redundant dual power-supply (hot-swappable) as well as all TX/RX modules are hot-swappable. Furthermore the TX/RX feature variable gain adjustment and RF power-monitoring while optionally the RedLink+ FLCRplus system also supports switchable LNB-supply.
