1 Narrow Linewidth Micro- Integrable Tunable Laser Assembly 6205-u ITLA Data Sheet

2 Lumentum narrow linewidth tunable lasers are a key component in today s agile transmission modules that are designed to support the rapid deployment of next- generation IP-based voice, data, and video services. The 6205-u narrow linewidth micro-integrable tunable laser assemblies (NLW µitla) are tailored for the needs of advanced modules that require fast wavelength tuning over C-band in an MSA form factor with reduced power consumption. The architecture and command set is based on the familiar OIF micro-itla IA standard. The key elements of the 6205-u micro-itla are the Sampled Grating Distributed Bragg Reflector (SG-DBR) laser, monolithically integrated with a semiconductor optical amplifier (SOA) and a micro wavelength locker, all enclosed in a high-reliability, hermetically-sealed TOSA package. The integrated SOA acts as a shutter during wavelength switching and as an optional variable optical attenuator (VOA) for transmitter power control. The RS232 communication interface is based on the OIF MSA standard and provides for comprehensive control and reporting functionality. This NLW µitla has a polarization-maintaining fiber pigtail and is shipped with an SC connector to facilitate customer incoming tests. Key Benefits Narrow linewidth (<300 khz) for coherent transmission applications 50 GHz channel spacing Standard and Extended C-band >37 nm operating range VOA function Polarization-maintaining fiber pigtail Hermetically-sealed tunable TOSA package with integrated wavelength locker Self-contained microprocessor control and monitor electronics Simple RS232 communication Low power consumption Applications Coherent transmit and local oscillator sources DWDM sparing Dynamic wavelength provisioning Dynamic add/drop multiplexers Optical cross-connects Wavelength conversion Compliance Compliant to OIF micro-itla IA footprint RoHS 6 2
