APRIL 16, 2007 --Civcom has expanded its transponder offerings for the optical data communications market by introducing its new TT600 Transponder. This 10-Gbit/sec widely tunable transponder has an optical dispersion tolerance enabling up to 600-km reach, the company says.

Civcom asserts that in addition to extending transmission reach to 600 km, the module maintains high performance at back-to-back and maximum reach in a low OSNR environment.

As metro and regional rings increase in size, the cost of the first line deployment increases. Using Civcom's Tunable Optical Dispersion Compensation technology and its Manageable Dispersion Compensation concept, the TT600 offers a cost saving plug-and-play alternative to dispersion compensating fiber. This provides network implementation, cost reduction, and storage area savings, says the company. In existing networks, the TT600 can be a substitute to the fixed-wavelength DWDM units employed in current telecom systems, substantially reducing deployment costs, according to Civcom.

The product will minimize size and cost while still enabling the widest possible tuning range in telecommunications equipment, says Civcom, operating in both the C-Band and L-Band frequencies and incorporates into a DWDM line card.

In addition, the TT600 contains a high-speed dynamic power tracking circuit, enabling the receiver to handle large and fast incoming power, transient to the photodiode. 50-GHz ITU grid wavelength spacing is available as well as various bit rates and applications including SONET/SDH, 10-Gigabit Ethernet, Fibre Channel, and FEC application, containing up to 11.3 Gbits/sec. Tuning the transponder wavelength and dispersion tolerance is possible through a standard I²C commands.

Civcom's TT600 transponder is now available for sample order.
