1550nm DFB Laser Diode, 20mW (CW) / 70mW (Pulsed), Single Mode Fiber-Coupled Coaxial Package with FC/APC Connector

Product Overview:

High Reliability 1550nm DFB Laser Diode

These 1550nm DFB laser diodes are InGaAsP multi-quantum well laser diodes coupled to a single-mode optical fiber. They are packaged in a hermetically sealed coaxial package and include an internal monitor photodiode. The CW output power is rated up to 20mW and the pulsed output power is rated up to 70mW. These laser diodes supports data rates up to 2.5 Gbps. The coaxial package is installed into a double-sided heat sink and mounting bracket for simple handling and mounting as well as enhanced thermal stability. These 1550nm lasers come standard with FC/APC connector; FC/PC is also normally in-stock. Please contact us for information on fiber connector options. The LD4B-1550-DFB-2.5G-20 is designed to operate in the most demanding scientific and industrial applications. Through the implementation of proprietary design, packaging, and fiber coupling technology, these laser diodes offer exceptional reliability and coupling efficiency stability vs temperature variation. Each individual laser diode undergoes extensive testing procedures before being shipped to guarantee the utmost quality. The module design is tested according to Telcordia GR-468-CORE standard.

Proper Handling and Operation of 1550nm DFB Lasers

Diode lasers are highly susceptible to damage from ESD and from temperatures exceeding their specified safe operating range. The user is advised to use care and proper ESD safety practices when handling them to avoid damage to the laser. A properly rated low noise current source, a low thermal resistance mount and a temperature controller should be used for optimal device performance and reliability.
