For the application of the board in WDM systems, see Figure 1. Figure 1 FIU board application in a WDM system NOTE: An OTU is a transceiver that can transmit and receive signals over the same wavelength at the same time. Functions and Features The main functions and features supported by the FIU are multiplexing or demultiplexing. For detailed functions and features, see Table 1. Table 1 Functions and features of the FIU board Functions and Features Description Basic function Implements the multiplexing and demultiplexing of the main path and the OSC. Optical power detection The TNF2FIU board supports optical power detection at multiplexing input (MI) optical ports whereas the TNF1FIU does not. WDM specification Supports both the DWDM and CWDM specifications. Operating wavelengths of the OSC Supports 1310 nm and 1611 nm wavelengths. Working Principle and Signal Flow The FIU unit consists of the following parts: optical module, optical power detection module, and communication module. Figure 1 is the functional block diagram of the TNF1FIU board. Figure 2 is the functional block diagram of the TNF2FIU board. Figure 1 Functional block diagram of the TNF1FIU board Figure 2 Functional block diagram of the TNF2FIU board Signal Flow The multiplexing module multiplexes the main path optical signals received through the RX optical port and the supervisory optical signals received through the SI optical port into one channel of optical signals. The one channel of signals is output through the OUT optical port. The IN optical port receives line optical signals, which are then sent to the demultiplexing module. The module demultiplexes the line optical signals into the main path optical signals and supervisory channel signals, and outputs them through the TX and SO optical ports respectively. Module Function Optical module Performs the multiplexing and demultiplexing of main path signals and supervisory channel signals. Optical power detection module Detects input optical power of service signals in a timely manner. NOTE: Only the TNF2FIU board supports the detection of input optical power. Communication module Communicates with the system control, switching, and timing board, to control and operate on each module of the unit. Front Panel There are ports on the front panel of the board. Appearance of the Front Panel Figure 1 shows the front panel of the FIU board. Figure 1 Front panel of the FIU board Indicators The FIU board does not have indicators. Ports Table 1 lists the type and function of each port. Table 1 Ports on the front panel of the FIU Port Connector Type Description Required Cable IN/OUT LC Receives/Transmits line signals. Connectors RX/TX LC Receives/Transmits main path signals. SI/SO LC Receives/Transmits OSC signals. Laser Hazard Level The laser hazard level of the board is HAZARD LEVEL 1M, indicating that the maximum power launched by the board ranges from 10 dBm (10 mW) to 21.3 dBm (136 mW). Valid Slots The FIU occupies one slot. Table 1 Valid slots for the FIU board Chassis Valid Slots 1800 V Chassis Sots 1-14, and slot 19 1800 I Chassis Sot 1, slot 3, and slot 4 1800 II Compact Chassis Sot 1 to slot 7 1800 II Enhanced Chassis Sot 1 to slot 6 1800 OADM Frame Sot 1 to slot 4 Display of Slots On the U2000, the board occupies one logical slot. When the board is installed in the 1800 I chassis, 1800 II chassis, the slot number displayed on the U2000, Web LCT, or in the command line represents the slot housing the board. When the board is installed in the 1800 OADM frame: If the 1800 OADM frame works with the 1800 I chassis, the slot number displayed on the U2000, Web LCT, or in the command line is a digit ranging from 7 to 10. If the 1800 OADM frame works with the 1800 II Compact chassis, the slot number displayed on the U2000, Web LCT, or in the command line is a digit ranging from 12 to 15. When the board is installed in the 1800 V chassis, the slot number displayed on the U2000, Web LCT, or in the command line represents the slot housing the board. Optical Ports This topic describes the display of optical ports on the board. Display of Optical Ports Table 1 lists the sequence number displayed in an NMS system of the optical ports on the FIU board front panel. Table 1 Display of the FIU optical ports Optical Port Optical Port Displayed on the NMS IN/OUT 1 RX/TX 2 SI/SO 3 NOTE: An optical port number displayed on the U2000 indicates a pair of actual optical ports, one for transmitting signals, and the other for receiving signals. FIU Parameters on the NMS This section lists the board parameters that can be set or queried by using the NMS. For parameters of the FIU, refer to Table 1. Table 1 FIU parameters Field Value Description Optical Interface/Channel - Displays the position of the optical interface. Optical Interface Name - Sets and queries the Optical Interface Name. An Optical Interface Name contains a maximum of 64 characters. Any characters are supported. Channel Number Mode C40 Mode, C80 Mode, CWDM Mode Default:/ Sets the number of wavelengths supported by the board. NOTE: When OptiX OSN 1800 I&II compact chassis uses the F1SCC board, this parameter is not supported. Launch Power(dBm) -60 to 60 Default:/ When the incident optical power of the transmission fiber is less than the nominal output power of the transmitting OA board, set Launch Power for the transmitting OA board to ensure desired main optical channel power adjustment effects in SOM function. See Setting Incident Optical Power for more information. NOTE: When OptiX OSN 1800 I&II compact chassis uses the F1SCC board, this parameter is not supported.
