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.

iConverter Single-Fiber CWDM/AD (User Manual)

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. CWDM over single-fiber increases network bandwidth capacity by enabling multiple wavelengths, or data channels that carry independent services over existing fiber infrastructure. Up to eight 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

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

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 Single-Fiber 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.
