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 3 illustrates two

CWDM/X modules with the 1310 Pass Band Port option.

Expansion Port
The Expansion Port (EXP) enables the cascading of two CWDM/X modules as

shown in Figure 4. On models 8860-2 and 8860-3, the Expansion Port can also

be used as a 1550nm Pass Band Port to transport legacy 1550nm single-mode

traffic as long as the spectral width of the1550nm legacy network is between 1510

and 1570nm.

Only the 4-Channel CWDM/X module is available with an optional Expansion

Port.
8-Channel CWDM/X MUXes require the use of the Band Splitter (8865-0) to multiplex

16 channels over the Common Port.

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 8000N-0) or a media converter

with integrated management (such as the iConverter 10/100M2)*.

2. Connect a single-mode, dual fiber duplex LC cable between the Channel Port of

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.

3. Connect a single-mode, dual fiber duplex LC cable between the Common Ports

on the CWDM/X modules (this connection may be made through fiber patch

panels since the modules may not be co-located). 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.

4. When cascading two 4-Channel CWDM/X modules, connect a single-mode,

dual fiber duplex LC cable between the Common Port on one CWDM/X module

and the Expansion Port on the other CWDM/X module (see Figure 5). 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 single-mode, dual fiber duplex LC cable from the legacy network

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.

NOTE: The iConverter CWDM/X modules can not be installed in slots 4, 8, 12 and

16 of a 19-Module Chassis or in the top slot of a 2-Module Chassis or in a 1-Module

Redundant Power Chassis.
NOTE: The iConverter 8-Channel Double-Wide CWDM/X can only be installed

in a 2-Module Chassis or 19-Module Chassis with the exception of slots 4/5, 8/9,

12/13 and 16/17.
*For complete management functionality, use M2 series (NMM2, GX/TM2, 2GXM2.

10/100M2, 2FXM2) or higher.
