iConverter CWDM/AD modules are Course Wave Division Multiplexing (CWDM) Optical Add/Drop Multiplexers (OADM). The CWDM/AD modules add (multiplex) and drop (demultiplex) selected channels, or wavelengths, on both directions of a CWDM common fiber link. 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. Access points can be added to linear, bus, and ring networks, where the dual-direction ring design provides redundant protected architecture.

The iConverter 1-Channel CWDM/AD modules multiplex and demultiplex one specific CWDM channel from the common CWDM fiber link. Ten models of the 1-Channel CWDM A/D are available to support the ten CWDM wavelengths from 1270nm to 1450nm, and eight models are available to support the eight CWDM wavelengths from 1470nm 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. 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 CWDM common fiber link.

When adding CWDM channels to legacy 1310nm and 1550nm networks such as SONET/SDH, the iConverter Lower Band OADM and Upper Band OADM modules can be used. The Lower Band OADM adds/drops the 1270nm to 1450nm band, allowing either legacy 1310nm services or lower band CWDM wavelengths to be added and dropped from the common fiber. The Upper Band OADM adds/drops the 1470nm to 1610nm band, for legacy 1550nm services or upper band CWDM wavelengths.

Multiple iConverter CWDM/AD devices can be inserted within a CWDM network. The low energy loss associated with each device minimizes the impact to existing wavelengths in the CWDM network.

iConverter CWDM/AD modules are passive devices that require no external power. They can also be installed in an iConverter powered chassis with a management module¹ and be managed using Omnitron’s NetOutlook® network management software, third-party SNMP software, Telnet or a serial console port.

iConverter CWDM/AD 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 common fiber link.

1 For complete management functionality, use M2 series (NMM2, GX/TM2, 2GXM2, 10/100M2, 2FXM2) or higher series.

In this application, an iConverter 4-Channel Multiplexer/Demultiplexer (CWDM/X) module is used to multiplex one T3 and three Gigabit Ethernet data channels onto one fiber common link, using example wavelengths 1470, 1490, 1590 and 1610. iConverter CWDM/AD modules are used to multiplex/demultiplex the 1470 and 1490 wavelengths from the fiber common link coming from the CWDM/X to Gigabit Ethernet switches, while the remaining wavelengths continue along the common link. At the end of the network, a third CWDM/AD is used to drop the 1590 wavelength to the Ethernet switch and the 1610 wavelength to the T3 router.

In this application, iConverter Dual-direction CWDM/AD OADM modules are utilized in a fiber ring architecture to provide point-to-point connectivity with redundant-path protection for two new Ethernet networks.

One OADM module is installed at each Ethernet switch location. Each module adds/drops the appropriate CWDM wavelength, while transparently passing the remaining wavelengths through the common ports.

Switches on Network A use the 1510nm wavelength. Switches on Network B use the 1530nm wavelength. Where two switches are located together, a 2-Channel CWDM/AD is used to enable access to both networks. Up to eight separate and independent networks can be deployed on the fiber ring using eight CWDM wavelengths (1470, 1490, 1510, 1530, 1550, 1570, 1590 and 1610nm).
