Omnitron iConverter CWDM/X

iConverter CWDM/XOmnitron’s iConverter CWDM/X Coarse Wave Division Multiplexing (CWDM) Multiplexer/Demultiplexer (MUX/DEMUX) modules support ITU-T G.694.2 wavelengths between 1270nm to 1610nm in 20nm increments. CWDM/X modules are protocol and rate transparent allowing different services up to 10Gbps to be transported across the same fibre link.

The passive iConverter CWDM/X modules are available in 4 and 8-Channel (wavelength) models, supporting a variety of wavelength combinations and port configurations.

The 4-Channel CWDM/X features an optional Expansion Port that can be used to cascade two MUX/DEMUX modules, doubling the channel capacity on the common fibre link. For example, two 4-Channel MUX/DEMUX modules can be cascaded to create an 8-Channel fibre common link.

Two 8-Channel MUX/DEMUX modules can be cascaded to create a 16-Channel fibre common link using the CWDM/X Band-Splitter. The Band-Splitter module combines and separates the lower CWDM channels (1270nm to 1450nm) and the upper CWDM channels (1470nm to 1610nm).

The CWDM/X features an optional 1310nm Pass Band Port that allows up to 8 CWDM channels to be overlaid on an existing legacy 1310nm network such as SDH or SONET (which normally operates in the 1260nm to 1360nm wavelength spectrum). The CWDM/X also features an optional Expansion Port that allows up to 8 CWDM channels to be overlaid on an existing legacy 1550nm network.

The small and compact size of the CWDM/X modules yields one of the highest port densities in the industry. Using the 2U high iConverter compact chassis, 38 CWDM/X modules can be installed, providing up to 684 connectors or up to 608 simplex channels or 304 duplex channels.

Benefits Include

  • Scalable to 8 or 16 channels using an optional Expansion Port or separate Band Splitter
  • Enables existing 1310nm networks to carry up to an additional 8 channels with optional 1310nm Pass Band Port

  • Highly compact form factor with up to 120 ports in a 2U chassis
  • Seamless integration with other iConverter media converters and chassis for multi-service platforms
  • Passive device that can also be installed in a powered chassis for managed applications
  • Management available with the addition of a management module to the chassis
  • Minimal and uniform optical loss facilitates easy network planning
  • Industry standard LC connectors
  • Commercial (0 to 50°C) and wide (-40 to 60°C) temperature ranges
  • One (1) Year Warranty and Free 24/7 Technical Support

Application Examples

Point-to-Point with Expansion Port

iConverter CWDM/X Application ExampleThis example shows a multiple channel (wavelength) multiplexing/demultiplexing application. The iConverter 19-module chassis at the top of the illustration is providing a multi-service platform in which the traffic from external T1/E1, T3/E3 and 100Mbps Ethernet sources is converted from copper-to-fibre using iConverter copper-to-fibre converters. Each converter is equipped with the appropriate CWDM channel Small Form Pluggable (SFP) fibre transceivers. The traffic from a fibre port on the Gigabit Ethernet switch is converted from its standard 1310nm wavelength to the appropriate CWDM channel using an iConverter xFF fibre-to-fibre transponder.

All four channels are connected to corresponding channels on a 8-Channel multiplexer, which are multiplexed over a fibre common link to the remote 4-Channel multiplexer. At the remote locations, the four channels are converted back to their original copper and fibre media using standalone converters.

The example also shows the addition of four extra channels using the Expansion Ports on the remote CWDM/X. The 8865-0 Band-Splitter (not shown) can also be used.




Point-to-Point CWDM with Pass Band on SONET Ring

This example shows two Gigabit point-to-point links connected over a segment of an existing SDH/SONET ring. Two 4-Channel iConverter CWDM/X modules with 1310 Pass Band (PB) ports are inserted into the SDH/SONET ring. The legacy 1310 SDH/SONET traffic continues to pass transparently through the CWDM/X devices unaffected. Two CWDM channels overlay the existing fibre link, creating two new point-to-point Gigabit Ethernet connections over the existing fibre, eliminating the need to install new fibre optic cabling.
