iConverter CWDM Multiplexers

Omnitron’s iConverter Coarse Wave Division Multiplexing (CWDM) Multiplexer/Demultiplexer modules support ITU-T G694.2 wavelengths between 1270nm to 1610nm in 20nm increments. iConverter CWDM modules are protocol and rate transparent allowing different services up to 10Gbps each to be transported across the same single-fiber or fiber pair link.

Omnitron’s iConverter CWDM networking products are a reliable and cost-effective solution for increasing bandwidth capacity over existing fiber infrastructure in Service Provider and Enterprise networks. These modular CWDM products multiplex up to sixteen independent wavelengths over a single fiber optic connection (either a fiber pair or a single fiber) in protected or unprotected configurations.

iConverter CWDM modules utilize a small and scalable plug-in form factor, and can be installed in any powered or unpowered iConverter chassis achieving some of the highest port densities in the industry.

The modules are designed to be integrated with other iConverter media converters and transponders to provide a true multi-service platform capable of delivering Ethernet, TDM, SONET and other services across a CWDM common link.

iConverter CWDM/X Multiplexer/Demultiplexer

Omnitron’s iConverter CWDM/X Coarse Wave Division Multiplexing (CWDM) Multiplexer/Demultiplexer (MUX/DEMUX) modules are protocol and rate transparent allowing different services up to 10Gbps each to be transported across the same fiber link. The small and compact size of the CWDM/X modules yields one of the highest port densities in the industry.

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 Single-Fiber iConverter CWDM/X modules are available in 2 and 4-Channel models.

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. The dual fiber 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.

iConverter CWDM/AD Add/Drop Multiplexer

iConverter CWDM/AD modules add (multiplex) and drop (demultiplex) selected channels, or wavelengths, on both directions of a CWDM fiber route. Using iConverter CWDM/AD modules, network designers can add new access points anywhere on a CWDM network, without impacting the remaining channels traversing the network.

The iConverter 1-Channel CWDM/AD modules multiplex and demultiplex one specific CWDM channel from the common dual fiber or single-fiber CWDM fiber link. Eighteen models of the 1-Channel CWDM/AD are available to support all CWDM wavelengths specified by ITU-T G.694.2, ranging from 1270nm to 1610nm.

The iConverter 2-Channel CWDM/AD modules offer the same functions as 1-Channel CWDM/AD modules but for two specific CWDM channels for fiber pair links. Models are available to support any two wavelengths from 1270nm to 1450nm, or any two wavelengths from 1470nm to 1610nm.

The 1 and 2-channel models can be used to transport channels in one direction or in both directions of the common CWDM fiber link.

CWDM Overview

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.
