REBLE610-ODU - 1

REBLE610-ODU XPIC ASI-IP-SDH link The REBLE610-ODU is the split version of REBLE610 Elber full indoor microwave link, from which it differs for the separation between the RF part (hosted in a waterproof aluminum case) from the modem, the I/O section and control. The indoor unit (or control unit) REBLE610-IDU is equipped with a hot-swappable redundant power supply, available both with AC and DC inputs. The modular approach has brought to the development of the data interface module (hosting modulator, demodulator and data interface) and the ODU communication module (with head supply and optical interface). From an RF point of view, the new transmission circuitry is able to guarantee around 1 Watt with every modulation scheme, introducing, in addition, wideband precorrection (up to 1GHz depending on frequency band). Major innovations on the digital inputs side with three different data interface boards available: version A is equipped with 10 ports ASI/ BTS on BNC connector, configurable as inputs or outputs, so that it is possible to include the ASI distribution and ASI matrix capabilities in the same equipment; it also provides a GbE port L1 for IP traffic, a 2048 Kbit/s E1 data channel (as an alternative to 2 ASI/BTS ports), and a “transit” connection (not to waste coaxial connectors); version B is equipped with 5 DVB-ASI/BTS/SMPTE310 ports (in or out) and 5 E1 channels; version C is oriented to TELCO and new generation broadcasting networks, offering both SDH and IP interfaces, with electrical and optical connections, integrating optionally a L2 switch with QoS capabilities. To transfer all these signals the channel capacity has been increased to 56MHz leading to a maximum throughput of 310Mbit/s; using an optional XPIC module (and an extra RELBE610) it is possible to duplicate the bitrate increasing to 610MBit/s, exploiting H and V polarizations and cancelling undesired contenta using special algorithms. Redundant configurations (SD and FD) are supported, as well as HSB adding CLEBER RF switch. A new management software offers complete control over device parameters and settings, an on-board TFT touchscreen allows a simple and intuitive user interface to check for anomalies. The same monitoring and control can be carried out through a particularly easy to use web interface and SNMP. ▪ Half-duplex, Full-duplex or Repeater ▪ Frequency: 2 2000-2300 3 3400-4200 4 4400-5000 5 5000-5500 6L 5925-6425 6U 6425-7125 7 7125-7825 8 7825-8500 10 10000-10700 11 10700-11700 13 12700-13200 14 14000-15500 Others on request. ▪ Direct frequency conversion (Zero-IF) ▪ Wideband (up to 1.3 GHz) ▪ Output power > 30 dBm in 128 QAM ▪ Very high spurious suppression ▪ Excellent noise figure ▪ High-speed modem integrated ▪ Interfaces: Version A: 10 x DVB-ASI/BTS 1 x E1 (2.048Mbit/s) 1 x GbE Version B: 5 x DVB-ASI/BTS/SMPTE310 5 x E1 (2.048Mbit/s) 1 x 10/100/1000BASE-T Version C: 2 x STM-1 2 x OC-3 4 x 10/100/1000BASE-T 2 x 1000BASE-X 1 x E1 (2.048Mbit/s) 1 x Voice Channel ▪ Bandwidth: 1.75÷56 MHz ▪ VBR up to 310 Mbps (620 Mbps with XPIC option) ▪ Integrated hitless switch for 1+1 configuration. ▪ Redundant hot-swappable power supply (AC and/or DC) ▪ W
