Omnitron’s iConverter CWDM/X Coarse Wave Division Multiplexing (CWDM) Multiplexer/Demultiplexer (MUX/DEMUX) modules support ITU-T G694.2 wavelengths between 1270nm to 1610nm in 20nm increments. iConverter CWDM/X modules are protocol and rate transparent allowing different services up to 10Gbps to be transported across the same fiber link.
The passive iConverter CWDM/X modules are available in 4 and 8-Channel (wavelength) models, supporting a variety of wavelength combinations and port configurations.
The CWDM/X features an optional Expansion Port that can be used to cascade two MUX/DEMUX modules, doubling the channel capacity on the common fiber link. For example, two 4-Channel MUX/DEMUX modules can be cascaded to create an 8-Channel fiber common link, or two 8-Channel modules can be cascaded to create a 16-Channel fiber common link.
The CWDM/X also features an optional 1310nm Pass Band Port that can be used to overlay up to 8 CWDM channels on an existing legacy 1310nm network such as SDH or SONET (which normally operates in the 1260nm to 1360nm wavelength spectrum). This feature allows the CWDM channels in the range of 1470nm to 1610nm to be overlaid on the same fiber pair as the existing 1310nm network with no changes to the legacy equipment.
The small and compact size of the CWDM/X modules yields one of the highest port densities in the industry. A 2U high
19-module iConverter chassis populated with modules can yield up to 120 channels of capacity.
iConverter CWDM/X modules are passive devices that require no external power. They can also be installed in an iConverter powered chassis with a management module and be managed using Omnitron’s NetOutlook® network management software, third-party SNMP software, Telnet or a serial console port.

The modules can be installed in any iConverter chassis equipped with other iConverter media converters and transponders to provide a multi-service platform capable of delivering Ethernet, TDM, SONET and other services across a CWDM fiber common link.

Point to Point with Expansion Port
This example shows a multiple channel (wavelength) multiplexing/demultiplexing application. The iConverter 19-module chassis at the top of the illustration is providing a multi-service platform in which the traffic from external T1/E1, T3/E3 and 100Mbps Ethernet sources is converted from copper-to-fiber using iConverter copper-to-fiber converters. Each converter is equipped with the appropriate CWDM channel Small Form Pluggable (SFP) fiber transceivers. The traffic from a fiber port on the Gigabit Ethernet switch is converted from its standard 1310nm wavelength to the appropriate CWDM channel using an iConverter xFF fiber-to-fiber transponder.
All four channels are connected to corresponding channels on a
8-Channel multiplexer, which are multiplexed over a fiber common link to the remote 4-Channel multiplexer. At the remote locations, the four channels are converted back to their original copper and fiber media using standalone converters.
The example also shows the addition of four extra channels using the Expansion Ports on the remote CWDM/X.
Point to Point CWDM with Pass Band on SONET Ring

This example shows two Gigabit point-to-point links connected over a segment of an existing SDH/SONET ring. Two 4-Channel iConverter CWDM/X modules with 1310 Pass Band (PB) ports are inserted into the SDH/SONET ring. The legacy 1310 SDH/SONET traffic continues to pass transparently through the CWDM/X devices unaffected. Two CWDM channels overlay the existing fiber link, creating two new point-to-point Gigabit Ethernet connections over the existing fiber, eliminating the need to install new fiber optic cabling.
CWDM technology provides the flexibility to increase capacity of existing fiber infrastructure by enabling multiple channels (wavelengths) over the same fiber cabling. Each channel carries data independently from each other, allowing network designers to transport different data rates and protocols (T1,T3, Ethernet, Serial, etc) for different customers or applications.
The wavelengths used with CWDM implementations are defined by the International Telecommunications Union, reference ITU-T G.694.2, listing eighteen wavelengths from 1270nm to 1610nm with 20nm wavelength spacing.
ITU-T G.652 single-mode fiber optic cable is not optimized for CWDM applications due to the high attenuation around the water peak region centered at 1383nm (wavelengths between 1390nm and 1410nm). The 1390 and 1410 wavelengths are not used on the standard models of iConverter CWDM/X MUX/DEMUX modules because of the high attenuation at the water peak.

* Note: The ITU standard specifies the exact center wavelength as 1271nm, 1291nm, 1311nm, etc. However, for clarity (and to comply with general industry conventions) this data sheet refers to these wavelengths as 1270nm, 1290nm, 1310nm, etc.
