Figure 3: Port Locations for 8-Channel Double-Wide CWDM/X Module Channel Port
The Channel Ports transmit and receive signals on specific CWDM wavelengths. The Channel Ports are multiplexed onto and demultiplexed from the Common Port.
Common Port
The Common Port (COM) transmits and receives the aggregated wavelengths connected to the Channel, Expansion and 1310 Pass Band Ports.
1310 Pass Band Port
The 1310 Pass Band Port (1310PB) allows a legacy 1310nm signal to pass through the CWDM/X module on a reserved band (1260nm to 1360nm). The port can be used to combine an existing legacy 1310nm network with up to 8 CWDM channels, allowing the CWDM channels in the range of 1470nm to 1610nm to be overlaid on the same fiber pair as the existing 1310nm network. Figure 4 illustrates two CWDM/X modules with the 1310 Pass Band Port option.

Installation
1. | Carefully slide the module into an open slot in an iConverter chassis. Align |
| the module with the installation guides and ensure that the module is firmly |
| seated against the backplane. Secure the module by fastening the front panel |
| thumbscrew(s) (push in and turn clockwise to tighten) to the chassis front. |
| The CWDM/X module requires no external power, however, if management is |
| required, the module must be installed in an iConverter powered chassis with a |
| Network Management Module (NMM2 Model |
2. | Connect a |
| the CWDM/X module and the attached device. It is important to ensure that the |
| wavelength of the CWDM/X matches the wavelength of the attached device. |
| Connect all Channel Ports in this manner. Ensure that the transmit (Tx) is |
| attached to the receive side of the device at the other end, and the receive (Rx) |
| is attached to the transmit side. |

The Expansion Port (EXP) enables the cascading of two CWDM/X modules as shown in Figure 5, supporting a variety of cascading combinations (4+4, 8+4, 8+8). The
Ensure that the transmit (Tx) is attached to the receive side of the device at the |
other end, and the receive (Rx) is attached to the transmit side. |
5. When overlaying a CWDM channel on an existing 1310nm legacy network, |
connect the |
to the 1310 Pass Band Port on the CWDM/X module. Ensure that the transmit |
(Tx) is attached to the receive side of the device at the other end, and the |
receive (Rx) is attached to the transmit side. |
