Omnitron iConverter CWDM/X and CWDM/AD

iConverter CWDM/ADiConverter Single-Fibre Course Wave Division Multiplexing (CWDM) modules provide a flexible and cost effective solution for increasing fibre capacity over single fibre networks. CWDM over single-fibre increases network bandwidth capacity by enabling multiple wavelengths, or data channels that carry independent services over existing fibre infrastructure. Up to eight separate data channels can be transported on a singlefiber link with iConverter Single-Fibre CWDM modules.

Single-Fibre CWDM/X Multiplexer/Demultiplexer Modules

Single-Fibre iConverter CWDM/X modules are available in 2 and 4-Channel models, supporting a variety of wavelength combinations and port configurations.

Single Fibre CWDM/X Diagram

The figure above shows a pair of 2-Channel, single-fibre CWDM/X units that operate using the 1550nm, 1570nm, 1590nm and 1610nm wavelengths. Note that each wavelength is unidirectional and only flows in one direction. The channel ports of iConverter CWDM/X model 8872 receive 1570nm and 1610nm, while the channel ports of model 8873 receive 1550nm and 1590nm.

Single-Fibre CWDM/AD Add & Drop Multiplexers

iConverter 1-Channel Single-Fibre CWDM/AD modules are Course Wave Division Multiplexing (CWDM) Optical Add and Drop Multiplexers (OADM). The CWDM/AD modules add (multiplex) and drop (de-multiplex) one channel on both directions of a CWDM single-fibre route. Nine standard models of the 1-Channel Single-Fibre CWDM/AD modules are available.

iConverter CWDM/AD modules add new access points anywhere on a single-fibre 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 small and compact size of the CWDM/AD modules yields one of the highest port densities in the industry. Using the 2U high iConverter compact chassis, up to 38 CWDM modules can be installed.

iConverter CWDM/X modules are passive devices that require no external power. They 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 fibre common link.

Application Example

The application below shows how the iConverter Single-Fibre CWDM/AD can enable protected path redundancy on a single-fibre ring.

Network A consists of two Fast Ethernet switches connected by two independent paths running Spanning Tree Protocol (STP). These switches are connected to the single-fibre ring using two 8878-55 iConverter Single-Fibre CWDM/AD modules. Both modules use 1550nm and 1570nm wavelengths. The 1550nm runs clockwise, and the 1570nm runs counter clockwise.

When the network is initialized, STP will choose an active path (segment) and a backup path (illustrated by the dotted line) for protection of the network. In the event of a fibre failure that interrupts the active path, both switches on Network A will switch paths and continue normal operation.

Network B consists of two Gigabit Ethernet switches connected by two independent paths, also running STP. Network B co-exists on the single-fibre ring in a separate CWDM channel, with no impact to Network A. Network B uses two 8878-59 iConverter Single-Fibre CWDM/AD modules. These modules use 1590nm and 1610nm wavelengths. Traffic on Network B is transparent to Network A. Both paths on Network B are also protected, and in the event of a fibre failure, both switches on Network B will switch paths and continue normal operation.
