Source Laser, VCSEL, 850 nm, 4.25 Gb/s, TOSA



This JDSU 850 nm LC connectorized TOSA (Transmit Optical Sub-Assembly) meets the requirements of demanding 4.25 Gb/s transceiver modules. The product utilizes a high performance, high reliability VCSEL integrated in a TO-46 package. Each device is actively aligned to a precision plastic LC barrel using a proprietary alignment algorithm and tested to precise requirements. The JDSU design produces excellent monitor current tracking over temperature. Each unit receives JDSU’s proprietary burn-in and stabilization process to ensure a low failure rate and long life expectancy while providing continuously consistent performance. Each part is electro-optically tested to ensure optimum performance and yield in the application.

The 4.25G TOSA converts an electrical signal into optical power at data rates up to 4.25 Gb/s and it is designed for performance over extended operating temperatures and power conditions with high reliability. The circular optical beam provides optimal power coupling to both 50/125 μm and 62.5/125 μm multimode fibers.
