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.
