Golden Valley, MN. – August 9, 2007 – Telecom Engineering today announces their new CWDM LiteTM Expansion Unit that increases installed CWDM multiplexer link capacity by 7, 15 or 22 channels.  The unit is a must have for dark fiber or CWDM users and operators who need to increase fiber bandwidth above existing CWDM multiplexer limitations. The ability to increase CWDM capacity is accomplished by the unit’s specially designed DWDM multiplexer that is capable of inserting 8 or 16 DWDM channels into unused CWDM channel bandwidth.  An 8 channel CWDM multiplexer link can be expanded to 15, 23 or 30 channels and a 16 channel CWDM multiplexer link can be expanded to 38 channels.  The unit is designed for easy installation onto existing live CWDM systems with minimal or no traffic interruptions, no power connection, no configuration and no reconfiguration of existing CWDM multiplexers.  A simple two step installation process of mounting into a rack and connecting fiber jumpers is all that is required for this unit to be ready for traffic. Additional product features include; data rate and protocol transparent to 10 Gbps, MTBF 1700 years, 1 RMU unit height, 19 or 23 inch rack mounting, and fiber connectors are easily accessible for cleaning.  The product is compatible with DWDM optics including XFP, SFP, GBIC, and Xenpak pluggables.
