Omnitron Systems Technology Band Splitter - Manual (Page 2)

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 (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-fiber
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 fiber 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 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.
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 specification for each model). Detailed calculations should
be performed for each fiber optic link in the network to ensure the proper optical devices are
specified with sufficient transmitter power.
