High Power DFB Laser for Communication

Description

The high power HST-DFB-BF14-x-x laser modules are designed for optical sensing and optical communication applications. These modules incorporate high output power while maintaining high linearity. The narrow line width and the option of using polarization maintaining optical fiber make it especially ideal for external modulation development.


Feature

• Standard OC-48 pin compatible

• Narrow spectral linewidth

• Low noise

• Compliant GR-468 reliability regulation
