T-Networks announces availability of four channel tunable transmitter
July 20, 2004 Allentown, PA -- T-Networks announced the availability of its new LLIM100 series tunable transmitter. It provides the same excellent performance and cost benefits of the Laser Integrated Modulator (LIM) platform but incorporates up to 4 x 50-GHz ITU channel tuning with wavelength locking. Two-channel and single-channel versions are also available with output powers to +4 dBm.
T-Networks entire unlocked product line, with up to 110-km transmission performance, non-return to zero and return to zero transmission, and up to +4dBm output power is now offered in single-channel wave-locked versions. In addition, tunable designs offer substantial savings in inventory and sparing costs, and can be used to incorporate remote provisioning with optical add-drop multiplexers. By covering up to 4 channels, the LLIM100 offers outstanding performance for metro and regional networks at costs substantially less than full C-band tunable, Lithium Niobate transmitters. With +/- 900 ps/nm dispersion tolerance, these transmitters are ideal for DWDM networks that incorporate amplification and dispersion management. Other dispersion characteristics are available upon request.
"We've seen significant demand for transmitters to address DWDM networks with 50-GHz channel spacing," said David Huff, vice president of Marketing and Business Development. "And these products offer substantial advantages for these networks over competing technologies." Those advantages include power, cost, size, and simplicity of implementation, according to the company. In keeping with the platform approach of the LIM, this product can be used in existing LIM designs with only minor modifications.
The Telcordia-qualified T-Networks LIM platform, based on EAMP technology, incorporates integrated Indium Phosphide (InP) lasers, modulators and optical amplifiers in a standard 7-pin EML-compatible package with inter-chip isolated coupling. The LLIM product line is sampling now.
