Avago introduces micro tunable laser assembly for coherent DWDM

Improves system performance for next generation 100G/400G networks

Avago Technologies has announced the availability of a new micro-integrated tunable laser assembly (Micro-ITLA) device. It is based on the company's proprietary external cavity laser (ECL) technology and InP and silica-on-silicon chip technology.

The device, the AFCU-UITLAXX,  is a high-performance Micro-ITLA component designed for both the transmission and local oscillator laser in coherent dense wave division multiplexing (DWDM) systems.

According to the company, it delivers a very narrow line-width, low phase noise and superior frequency accuracy improving system performance by reducing signal-to-noise penalties. With no moving parts, the device achieves excellent operational shock and vibration resistance.

Besides its narrow linewidth, the new Micro-ITLA device features a high optical output power, off-grid tuning capability, a gridless channel plan and in-operation wavelength and power adjustment capability suitable for applications in 100G PM-QPSK and 200G 16-QAM modulation formats. The device conforms to the OIF Micro-ITLA implementation agreement.

Avago will be showing the device at the OFC 2015 exhibition in Los Angeles, California from March 24th to 26th.
