The RedLink RF-over-Fiber redundant chassis FLCR101 (1RU/19") and FLCR416 (4RU/19") allow flexible, high quality and absolute secure optical transmission of max. 16 L-Band, 10MHz* or IF signals in a 1:1 redundant operation over a distance of up to 10 km. The 1RU/19" FLCR101 chassis can be equipped with 2 optical modules (TX/RX) while one is actively operating and 1 hot-standby so to assure a 1:1 optical transmission redundancy. The 3RU/19" FLCR416 chassis can hold up to 32 optical modules (TX/RX) while 16 are actively operating and 16 hot-standby assuring a 1:1 optical transmission redundancy. The chassis are designed to allow mixed configurations for insertion of L-Band, 10MHz* or IF TX and/or RX modules within the same chassis. Furthermore the chassis are equipped with corresponding RF ports, acting either as input or output port as per the individual configuration. The redundancy switching can be realized manually via the front panel LC-Display/touchscreen and remotely via the Ethernet-Interface (http/WebGUI, SNMP). The RedLink system features an automatic redundancy switching as per preconfigured adjustments. Once an active TX or RX module fails the corresponding hot-standby TX/RX module becomes active manually or automatically assuring interruption free signal transmission. The redundant RedLink system features a front side LC-Display or 8" touchscreen as well as remote interfaces for remote access and configuration. Besides this the Redlink features Laser, Link and RF power monitoring, gain adjustment and switchable LNB-supply.
