iConverter Single-Fiber Course Wave Division Multiplexing (CWDM) modules provide a flexible and cost-effective solution for increasing the fiber capacity of single fiber networks. Up to ten separate data channels can be transported on a single-fiber link with iConverter Single-Fiber CWDM modules.

The iConverter CWDM/X and CWDM/AD single-fiber modules are protocol and rate transparent allowing different services up to 10Gbps to be transported across the same common fiber link. The single-fiber modules support dual fiber Channel Ports and single-fiber Common Port connections. Each fiber strand on the Channel Port supports a different wavelength, one wavelength for transmit (TX) and a different wavelength for receive (RX).

Single-Fiber CWDM/X Multiplexer/Demultiplexer Modules

Single-Fiber iConverter CWDM/X modules are available in 2, 4 and 5-Channel models, supporting a variety of wavelength combinations and port configurations. In pointto-point applications, the CWDM/X modules operate in pairs, maximizing the number of wavelengths supported.

The Single-Fiber iConverter 5-Channel CWDM/X modules support five bidirectional wavelengths channels between 1431nm to 1611nm with a 1310nm Pass Band Port. An optional Optical Time Domain Reflectometer (OTDR) port is available which provides the ability to test the integrity of the fiber optic link without disturbing the wavelength channels.

The 5-Channel CWDM models also support up to ten unidirectional data channels for data/video overlay networks.

Single-Fiber CWDM/AD Add & Drop Multiplexers

iConverter 1-Channel Single-Fiber CWDM/AD modules are CWDM Optical Add and Drop Multiplexers (OADM). The CWDM/AD modules add (multiplex) and drop (de-multiplex) one channel on one or both directions of a CWDM single-fiber link. Nine standard models of the 1-Channel SingleFiber CWDM/AD modules are available.

iConverter CWDM/AD modules add new access points anywhere on a single-fiber 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.

Linear Add/Drop

In this application, 1-Channel SF OADMs and a 4-Channel SF MUX/DEMUX module creates a linear network dropping services off to four sites on a single-fiber common link.

At the headend, a 4-Channel single-fiber MUX/DEMUX is used to connect four Ethernet switches each supporting two wavelengths over a common fiber link. At the first site, a 1-Channel OADM is installed to remove and add the 1470/1490nm wavelength which is associated with Network A. The remaining wavelengths (1510/1530nm, 1550/1570nm and 1590/1610nm) are passed through the OADM to the next site.

The 1510/1530nm wavelength associated with Network B is dropped at the second site while the 1550/1570nm and 1590/1610nm wavelengths are passed on to the last two sites. The 1550/1570nm wavelength associate with Network C is dropped at the third site. Since only 4 channels are used, the last site does not need a OADM module.

Basic Application Diagrams

Below are block diagrams representing a 4-Channel CWDM Single-Fiber point-to-point application and a 4-Channel CWDM Single-Fiber point-to-point with an OADM somewhere in between the 4-Channel MUXs.

All Single-Fiber modules have dual fiber channel ports and single-fiber common ports. The CWDM SFP transceiver required for any single-fiber application depends on the Rx wavelength of the Single-Fiber module.

In the 4-Channel point-to-point diagram below, the CWDM SFP transceiver wavelength needed for Channel 1 of the 8877-0 module is 1470nm.

In the 4-Channel point-to-point with OADM, the CWDM SFP transceiver wavelength needed for the OADM Channel 1 Left is 1490nm and for Channel 1 Right is 1470nm.
