Lumentum 50G Narrow Linewidth OIF Micro ITLA C Band 96CH 5-14dBm 22023180

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.
