The Avago AFCU-UITLAXX is a narrow linewidth micro-integrated tunable laser assembly (Micro-ITLA) device designed for both the transmission and local oscillator laser in coherent dense wave division multiplexing (DWDM) systems.
Based on Avago’s proprietary external cavity laser (ECL) technology and proven indium phosphide (InP) and silica-on-silicon chip technology and packaging platform, the device delivers a very narrow linewidth, 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.
The AFCU-UITLAXX also 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. With only one-third (1/3) the size and 25% less in power consumption compared to the industry standard large form factor ITLA, the device enables customers to migrate to smaller size optical linecard solutions or pluggable transceivers for next generation 100G and 200G/400G transmission systems.
