Narrow Linewidth Micro-Integrable Tunable Laser Assembly
Lumentum narrow-linewidth tunable lasers are a key component of today’s agile transmission modules support the rapid deployment of next‐ generation IP-based voice, data, and video services.
The assemblies meet 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.
