The JDSU Agile Transmission Modules family includes tunable transponders and tunable lasers. The flexibility enabled by JDSU's transponders is critical to the successful and rapid deployment of next generation, IP-based voice, data and video services which are driving new network management challenges for communications service providers. They also support multiple modulation formats to allow multiple applications, from ultra long haul to metro networks, in a single platform. The 3205-D/3206-D Widely Tunable Laser Subassembly (TLSA) is designed for use in DWDM systems where the capability to change wavelength on demand over the entire C- and L-Bands with 50 GHz channel spacing is essential. The architecture and command set are the same as those of the complete 3205/3206 assembly; however, the subassembly has a lower profile. The key elements of the TLSA 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 TLSA also incorporates a digital controller and firmware. Polarization maintaining fiber pigtail is standard, with a ceramic ferrule termination. User control may be specified as I2CTM, SPI, or UART.

TLSA Installation
The TLSA electrical connector pins will withstand mating forces similar to those of internal personal computer ribbon cables. Because the complete TLSA is not hermetically sealed, do not immerse it or spray it with cleaning solutions or solvents. The fiber connector handling/protection (dust) cap and the fiber pigtail materials can deform at temperatures above +85C.
TLSA Handling Considerations
Although the TLSA has been designed to be physically robust, use care during handing and installation. Keep optical connector clean and free of surface particles. Keep the optical connector handling/protection cap in place when the fiber pigtail is not mated. Oil-free canned air or nitrogen with an extension tube may be used to help remove surface particles. Observe normal industry procedures for handling and cleaning. Use care in controlling the minimum fiber bend radius. Make sure that the protection cap is debris-free and clean prior to reinstalling it on the optical connector.
