1625nm wavelength has been increasingly becoming an important wavelength in optical fiber communication networks. Utilizing the L band of the transparent window of a optical fiber can increase the capacity of an optical link with lower cost and shorter lead time. 1625 nm laser diodes and 1550/1625 nm WDM optical components are designed for such purpose.

This is a low cost DFB laser diode with high optical output power, built-in optical monitor and wide operating temperature range.

Features:

• MQW 1625 nm DFB laser diode
• Low threshold current
• High output power (up to 4mW)
• Built-in InGaAsP monitor photodiode
• Wide operating temperature range (from -45 to +85 C degree)

Applications:

• Optical source, data transmission
