New Hardware
4.1 New Hardware Overview
This release introduces several modules that can be used to support the ONS 15216 FlexLayer Asymmetric DWDM solution. The new part numbers are listed in Table 4-1.
4.2 Eight Channel Optical Add or Drop FlexLayer Module
The 8 channel Add/Drop FlexLayer module is a completely passive unidirectional component that allows the insertion or the extraction of 8 channels within the ONS 15216 channel plan. Four specific modules are available to cover the whole 32-channel bandwidth (see Figure 3-1 on page 3-3).
Figure 4-1 shows the unit functional block diagram. In reference to Figure 4-1, the signal flows from left to right when the unit is used as a drop site and from right to left when the unit is used as an add site.
Figure 4-1 Eight Channel Add or Drop FlexLayer Module Block Diagram
When the unit is used as a drop component, the WDM composite signal coming from the DROP-COM-RX port is filtered sequentially by a band and a channel filter and the filtered channels are dropped at the eight DROP-CH-TX ports. The rest of the WDM composite signal is sent to the DROP-COM-TX port. A 2% tap coupler, DROP-MON, is used to monitor the input WDM composite signal.
When the unit is used as an add component, the eight channels coming from the 8 ADD-CH-RX parts are added to the WDM composite signal coming from the ADD-COM-RX ports. The muxed WDM composite signal is sent to the ADD-COM-TX port. A 2% tap coupler, ADD-MON, is used to monitor the muxed WDM composite signal.
Figure 4-2 shows the physical appearance of the ONS 15216 8-Channel Add/Drop FlexLayer Module.

Labels are provided to show how the unit ports are mapped. It is the end user's responsibility to label the unit for its intended use (drop or add component). Figure 4-3 shows how the connectors are mapped and labeled in the front panel when the component is used as a Drop. The COM-RX is mapped to port 1, the COM-TX is mapped to port 12, and the eight dropped channel TX ports are mapped to ports 2 to 5 and 8 to 11. The 2% tap MON port is mapped to port 6. Port 7 is not active.

The COM-TX is mapped to port 1, the COM-RX is mapped to port 12, and the added channels are mapped to the eight RX ports 2 to 5 and 8 to 11. The 2% tap MON port is mapped to port 7. Port 6 is not active.

4.3 Two Channel Optical Add or Drop FlexLayer Module
The 2 channel Add/Drop FlexLayer module is a completely passive unidirectional component that allows the insertion or the extraction of 2 channels within the ONS 15216 channel plan. Sixteen specific modules are available to cover the whole 32-channel bandwidth (see Table 3-1 on page 3-1).
Figure 4-5 shows the unit functional block diagram. In reference to Figure 4-5, the signal flows from left to right when the card is used as a drop and from right to left when the card is used as an add.
Figure 4-5 Two Channel Add or Drop FlexLayer Module Block Diagram
When the unit is used as a drop component, the WDM composite signal coming from the DROP-COM-RX port is filtered sequentially by two filters and the filtered channels are dropped at the two DROP-CH-TX ports. The rest of the WDM composite signal is sent to the DROP-COM-TX port.
A 2% tap coupler, DROP-MON, is used to monitor the input WDM composite signal.When the unit is used as an add component, the added channels coming from the 2 ADD-CH-RX ports are combined with the WDM composite signal coming from the ADD-COM-RX port. The muxed WDM composite signal is sent to the ADD-COM-TX port. A 2% tap coupler, ADD-MON, is used to monitor the muxed WDM composite signal. Figure 4-6 shows the physical appearance of the ONS15216 Two Channel Add/Drop FlexLayer Module.

4.4 Optical Splitter or Coupler FlexLayer Modules
The 1:x Splitter/x:1 Combiner (x being 2, 3, or 4), are completely passive star coupler components (wavelength insensitive) that can be used as splitters or couplers. These modules can be used to couple the composite outputs (ADD-COM-TX ports) of the Optical Add/Drop FlexLayer modules or split their input signal to the composite input (DROP-COM-RX) of the Optical Add/Drop FlexLayer modules.
Figure 4-9, Figure 4-10 and Figure 4-11 show the unit block diagrams of the 1:2 Splitter/2:1 Coupler, 1:3 Splitter/3:1 Coupler, and the 1:4 Splitter/4:1 Coupler respectively. With reference to the Figure 4-9, Figure 4-10, and Figure 4-11, the signal flows from bottom to right when the component is used as a coupler and from right to bottom when the component is used as splitter.
When the module is used as a coupler, the individual signals enter the card from the CPL-RX ports and are coupled together through a passive star coupler to the CPL-TX port. All ports are not wavelength selective (in the operating wavelength range).
When the module is used as a splitter, the composite signal enters the card from the SPL-RX port and is split through a passive star coupler to the SPL-TXn ports. These modules (although designed to pass wavelengths associated with the ONS15216 32 channel plan) are not selective to specific wavelengths (units do not filter wavelengths).

4.5 Y-Cable Protection Module
The Y-cable protection module is a bidirectional module. It is equipped with a passive star coupler that is used as a splitter and a passive star coupler used as a coupler.
Note
This unit is not to be used for VoD applications, nor are the other modules of this equipment release.
The purpose of this module is to provide Y-Cable protection for transponder cards such as the ONS15454 multirate and 10G transponders. (See Figure 4-21) There are two versions of this unit, one for multimode applications (CS-MM-Y) and one for single mode applications (CS-SM-Y).Typical Y-Cable Protection Module Configuration
Figure 4-21 Typical Y-Cable Protection Module Configuration
Figure 4-22 shows the unit block diagram of the Y-cable protection module. When the module is used in the coupler direction, the individual signals enter the module from the CPL-RXn ports and pass through a passive star coupler to the CPL-TX port.
It is important to note that the coupler is not meant to combine both the protecting and working client card signals. The module allows a path for the working client transmit interface to connect to the network in the event the opposite interface in the protection pair should fail (the protecting interface switches to the working interface).
When the module is used in the splitter direction, the signal enters the module from the SPL-RX port and is split through a passive star coupler to the SPL-TXn ports. This module (although designed to pass wavelengths associated with the ONS15216 32 channel plan) are not selective to specific wavelengths (units do not filter wavelengths).

4.6 Four Channel Optical Variable Attenuator (VOA) FlexLayer Module
The 4 channels VOA module is a completely passive unidirectional component that allows equalizing the optical power of up to 4 channel groups. These modules are aimed to provide the ONS 15216 platform the capability of supporting VoD applications.
Figure 4-26 shows the unit functional block diagram. The input signals always flow from the VOA#-RX ports to the VOA#-TX ports. The pound (#) in the previous name convention identifies the number ports and is limited from 1 to 4. The input signals are attenuated by the manual adjustment of the variable optical attenuators (VOAs) that are placed between the input and output ports.
