Product Overview:

1550nm DFB Single Mode / Single Frequency Laser Diode, 10mW

Eblana's DFB laser is built using discrete-mode (DM) technology, delivering a cost-effective laser diode with mode-hop free tuneability, excellent SMSR, and narrow linewidth.

The model EP1550-DM-H laser diode from Eblana Photonics is available at wavelengths from 1540nm - 1560nm for a wide range of communications applications.

1550nm for Telecommunications Applications

Eblana's 1550 nm DM Laser delivers reliable, mode-hop free, operation over a wide operating temperature range. These single longitudinal mode lasers are designed specifically for use in 10 GHz communication systems. The narrow linewidth output improves performance across a wide range of application conditions.

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.
