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 iConverter CWDM/X and
The small and compact size of the iConverter CWDM/X and
CWDM/AD modules yields one of the highest port densities
in the industry. A 2U high 19-module iConverter chassis
populated with modules can yield up to 120 wavelengths of
capacity.

iConverter CWDM/X modules are passive devices that require
no external power. They can also be installed in an iConverter
powered chassis with a management module

and be managed
using Omnitron’s NetOutlook

network management software,
third-party SNMP software, Telnet or a serial console port.
The modules can be installed in any iConverter chassis
The 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 fiber common link.

For complete management functionality, use M2 series (NMM2,
GX/TM2, 2GXM2, 10/100M2, 2FXM2) or higher.
Two Networks on a Single-Fiber Protected Ring

The application below shows how the iConverter Single-Fiber
CWDM/AD can enable protected path redundancy on a single-
fiber ring.
Network A consists of two Fast Ethernet switches connected by
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-fiber ring using two
8878-55 iConverter Single-Fiber CWDM/AD modules. Both
modules use 1550nm and 1570nm wavelengths. The 1550nm
runs clockwise, and the 1570nm runs counterclockwise.

(segment) and a backup path (illustrated by the dotted line)
for protection of the network. In the event of a fiber 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
Network B consists of two Gigabit Ethernet switches connected
by two independent paths, also running STP. Network B co-
exists on the single-fiber ring in a separate CWDM channel,
with no impact to Network A. Network B uses two 8878-59
iConverter Single-Fiber 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 fiber failure, both switches on
Network B will switch paths and continue normal operation.
