Owner's manual

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 rmly seated against the
backplane. Secure the module by fastening the front panel thumbscrew (push in and turn
clockwise to tighten) to the chassis front. The CWDM/X Band Splitter 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)*.
*For complete management functionality, use M2 series (NMM2, GX/TM2, 2GXM2. 10/100M2,
2FXM2) or higher.
2. When using the CWDM/X Single Band Splitter to combine two 8-Channel CWDM/X
modules, connect the CWDM/X MUX with the wavelengths range of 1270nm to 1470nm
to the Lower Band Port. Connect the CWDM/X MUX with the wavelengths range of
1470nm to 1610nm to the Upper Band Port.

3. When using the CWDM/X Single Band Splitter to combine two 4-Channel Single-ber
CWDM/X modules, connect the CWDM/X MUX with the wavelengths range of 1270nm
to 1470nm to the Rx side of the Lower Band Port. Connect the CWDM/X MUX with the
wavelengths range of 1470nm to 1610nm to the Rx side of the Upper Band Port. The Tx
side of the Common Port is used as the common ber link.

4. When using the CWDM/X Dual Band Splitter to add a wavelength to an existing 1310nm
legacy ring or linear topology, connect the CWDM A/D Common Ports to the Channel 2
Ports on the CWDM/X Dual Band Splitter (CH1: 1270nm to 1450nm, CH2: 1470nm to
1610nm). Connect the new wavelength application to the Channel Ports on the CWDM
A/D. Connect the existing 1310nm legacy device to Channel 1 Ports on the CWDM/X
Dual Band Splitter.

5. Connect a single-mode, dual ber duplex LC cable between the Common Ports on the
CWDM/X modules (this connection may be made through ber 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.
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.
Design Considerations
iConverter CWDM/X modules are passive devices that require no external power. Attenuation
(signal loss) of less than 0.8dB will be realized through each port on the module (see the
CWDM/X Data Sheet for exact loss specication for each model). Detailed calculations should
be performed for each ber optic link in the network to ensure the proper optical devices are
specied with sufcient transmitter power.
