The LD4B-1550-DFB-2.5G-15 is a wavelength stabilized, multiple quantum well distributed feedback grating laser diode (MQW DFB) coupled to an optical fiber. This laser diode is mounted in a coaxial package with an internal photodiode.
Highest Reliability Rating: Designed and Tested to Telcordia GR-468-CORE Compliance Standards
These lasers diodes are designed for compliance with Telcordia GR-468-CORE standards. This standard is a widely recognized standard that outlines the reliability and quality assurance requirements for optoelectronic devices, particularly semiconductor laser diodes and photonic components used in telecommunications. This standard ensures the long-term performance and durability of laser diodes and optoelectronic components.
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.
Mounting and Temperature Control: In order to maintain the lifetime of a laser diode, proper heat management is essential. Due to the design of the laser diode, heat is typically dissipated only through the base plate of the diode‘s package. A proper heat conducting interconnection between the diodes base plate and the heat sink must be maintained. Some devices require the use of a thermo-electric temperature controller (TEC controller) to remove the heat from the laser and stabilize the temperature.
