JDSU CW-TOSA 80CH C Band 50G 5205-T Integrable Tunable Laser ITLA 21130212-004/6

JDSU tunable lasers are a key component in today's agile transmission modules that are 

designed to support the rapid deployment of nextgeneration Internet Protocol (IP)-based voice, data, and video services.

The 5205-T/5206-T Integrable Tunable Laser Assemblies (TOSA-based ITLA) are tailored 

for the needs of advanced modules that require fast wavelength tuning over C-band or 

L-Band, respectively, in an MSA form factor with reduced power consumption. The architecture 

and command set is based on the familiar OIF-ITLA-MSA standard. 

The key elements of the 5205-T/5206-T ITLAs are the Sampled Grating Distributed Bragg 

Reflector (SG-DBR) lasers, monolithically integrated with a semiconductor optical amplifier (SOA) 

and an integral 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 pre-emphasis of transmitter power levels to optimize link performance.

The RS232 communication interface is based on the OIF MSA standard and provides for comprehensive 

control and reporting functionality. This TOSA based ITLA has a polarization-maintaining fiber pigtail 

and is shipped with an SC connector to facilitate incoming tests prior to splicing.
