5205/5206 Integrable Tunable Laser Assembly (ITLA) (PDF, 0.30 MB)
The JDSU Agile Transmission Modules family includes tunable transponders and tunable lasers. The flexibility enabled by JDSU tunable modules is critical to the successful and rapid deployment of next generation, IP-based voice, data, and video services which drive new network management challenges for communications service providers.
The 5205/5206 Integrable Tunable Laser Assembly (ITLA) is designed for use in DWDM systems where the capability to change wavelength on demand over the extended C- and L-Bands with 25 or 50 GHz channel spacing is essential. The architecture and command set are based on the OIF-ITLA-MSA standard.
The key elements of the ITLA are the Sampled Grating Distributed Bragg Reflector (SG-DBR) laser, monolithically integrated with a Semiconductor Optical Amplifier (SOA) and an integral wavelength locker, all enclosed in a high-reliability, hermetically sealed 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 ITLA also incorporates a digital controller and firmware. A polarization-maintaining fiber pigtail is standard with a ceramic ferrule termination. An RS-232 communication interface provides for comprehensive control and reporting functionality.
