Product Overview:

1550nm DFB Laser with Single Mode Fiber Pigtail and FC/APC Connector:

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. The laser 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 lasers come standard with FC/APC connector; FC/PC is also normally in-stock. Please contact us for information on fiber connector options.

Proper Handling and Operation of Diode 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.
