CWDM/X 4 and 8 Channel Multimode
MUX/DEMUX USER MANUAL
Product Overview
The iConverter 4 and 8 Channel Multimode Coarse Wave Division Multiplexing
(CWDM) Multiplexer and Demultiplexer plug-in modules facilitate significant increase
in the capacity of existing multimode fiber networks.
CWDM/X multimode multiplexers are protocol and rate transparent, allowing Ethernet,
Fibre Channel and SDH/SONET and other services up to 10Gbps each to be transported
across the same fiber link. The modules support ITU-T G.694.2 wavelengths between
1270nm to 1610nm in 20nm increments.

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 Ports.

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 M2, M3 or M4 series module).
2. Connect a mode conditioning cable between the Channel Port of the CWDM/X
module (multimode) 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.
Mode conditioning cables are used to adapt the single mode transceivers to a
multimode cable network. In example (A), the Gigabit Ethernet switch has fixed fiber
multimode optics and can not be upgraded to single-mode. A transponder is used to
converter the multimode optics to single-mode CWDM optics. A mode conditioning
cable is used to connect to the transponder to the channel port on the CWDM/X
Multimode MUX.
In example (B), the Gigibit Ethernet switch supports SFP transceivers, so a CWDM
SFP single-mode transceiver is installed. A mode conditioning cable is used to connect
to the CWDM transceiver to the channel port on the CWDM/X Multimode MUX.
3. Connect a multimode, 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.
