Introducing the new OTx optical headend from Global Invacom. Fully compatible with all the current FibreIRS equipment and designed for future compatibility

Main features:

• Replaces both the ODU32 and fibre LNB.
• 1310 nm option either as a kit with a wideband LNB included or as a standalone unit.
• Fully compatible with all existing GTU’s and SwitchBlade units. The output frequency stacking has not changed.
• Familiar FC/PC connection.

• Wideband LNB input. Unlike the previous ODU32 that required a specific wholeband LNB with frequencies above 5GHz, the OTx unit uses standard H & V wideband inputs.• The wideband LNB supplied in the kit uses a local oscillator set to 10.41GHz• Single optical output with a 7dBm 1/32 split ratio. ODU32 units are more costly but would offer two 1/32 split optical outputs. If more than 32 splits are required, additional equipment will be needed.• IP65 rated and can therefore be installed outside. Intended to be fitted behind the dish itself. Ensure that it is mounted vertically.• 5G/700MHz filtered input accepting frequencies 88 - 694MHz. Additional channel processing with channel conversion is recommended with transmitters that still offer COM7 at channel 55.• Vertical leg powering of the wideband LNB only. For horizontal signal testing, it is recommended that power is fed to the LNB via the vertical leg connection of the powered OTx unit.FibreIRS FC/UPC optical outputFully compatible with GI O2O and existing FibreIRS systemsWideband inputWall or pole mount1310nm versionOpticalOptical wavelength (D000410): 1310nm ±20Optical wavelength (D000435): 1550nm ±15Optical output power: +7dBmReturn Loss: 20dBRF Signal SatelliteInput frequency Wideband (MHz): Min 290 / Max 2340Gain variation across band: Max 3dB *Gain ripple across 28Mhz: 1dBNominal impedance: 75ΩInput power (dBµV): Min 70 / Max 85 (For 40 transponders)* additional variation can occur due to satellite transmitted signal levels.RF Signal TerrestrialInput frequency (MHz): Min 88 / Max 694Gain ripple across 28Mhz: 1dBInput power (dBµV): 70DC specificationInput voltage: 20VCurrent consumption: 350mA Max (Excluding connected devices)Output voltage Vertical and Terrestrial: 12VOutput voltage Horizontal: 18VMaximum upstream current: 500mAConnectorsInput: 3 x F connectorOutput: 1 x FC/UPCPower supply: 1 x F connectorEnvironmental SpecificationOperating temperature: -20°C to +60°CStorage temperature: -40°C to +70°C

IF +DTT/DAB LNB c/w ODU32 Optical Combiner
(1.5m N Connector HF Lead c/w PSU - DC via
'F' Connection), Optical output 1550nm. 2 x 32

The Fibre system is designed to run alongside a voice and data optical network,either on its own dedicated fibre, or as an RF overlay. The system is designed to distribute DAB, DTT and the complete Satellite content from a single Headend to large number of dwellings.

The Headend is comprised of modules that receive and combine terrestrial and satellite signals to an optical output. The optical signal is then  split, amplified, then split further to feed multiple Passive Optical Networks (PONs) or ‘Point to Point’ connections.

Each home has it’s own Fibre-IRS optical to legacy converter, which outputs all of the inputs in their conventional format and at the original frequencies (DTT, DAB plus 4 Universal LNB O/Ps).

The Fibre-IRS Gateway Termination Unit (GTU) is designed to convert the optically received Fibre IRS signals (either via a dedicated Fibre or RF Overlay) to legacy format, e.g. with all inputs (DTT, DAB plus 4 quadrants of a universal LNB) being converted to their conventional format and at their original frequencies.

At the Head End, the F-IRSODU32 combines the signal from a Wholeband LNB (included with ODU32 Kit) with a DTT/DAB signal. The, now optical, digital IRS signal is output via 2 low power lasers contained within the ODU32.

Each of the 2 Optical outputs can be split, using GI Optical Splitters, to feed up to 32 FibreIRSGTU (Gateway Termination Units) Quads or Quattro..
