TO293BU-CDZ [Broadcom]

The TO293 CWDM is a hermetically sealed device with a photo diode for optical output monitoring. It incorporates 1270nm to 1450nm single mode edge-emitting laser diode chips for use in uncooled applications up to 10.7Gb/sec. The laser is mounted into a TO header and is hermetically sealed with a specific lens cap. The laser design is buried hetero structure with multi-quantum well (MQW) active layers and distributed-feedback (DFB) grating layer. All laser chips come from wafers that have been certified using a representative lot of devices that must achieve an acceptable yield for burn-in and other multi-temperature, CW and dynamic tests. Features include low threshold current, high bandwidth, qualified as per intent of Telcordia GR-468, and operating temperature -40 °C to 85 °C.
