The PL-980-FP-C-A81-PA is 980 nm pump laser modules uses a number of revolutionary design steps and the very latest material technologies to significantly improve scalability of the production process. The semicooled 45°C laser diode operation provides for a significant reduction in TEC and overall power consumption. The module meets the stringent requirements of the telecommunications industry including Telcordia GR-468-CORE for hermetic 980 nm pump modules.
The LD-PD Series pump module, which uses Fiber Bragg grating stabilization to lock the emission wavelength, provides a noise-free, narrowband spectrum even under changes in temperature, drive current, and optical feedback. Wavelength selection is available for applications requiring the highest performance in spectrum control with the highest power available.

Note:
● Extreme operating conditions refer to the highest ratings that a device can withstand for a short period of time. Operating beyond the maximum ratings may cause permanent damage to the device. Prolonged exposure to any maximum rating conditions may affect the reliability and service life of the device.
● Unless otherwise specified, device operating conditions: case temperature -5°C ~ +75°C, FBG temperature -5°C ~ +75°C, LD operating temperature 25°C (at any given case temperature), PD bias voltage -5V.
