- Above specification are for device without connector, and may change without notice.
- Other package dimension and optical performance can meet customer design.
- IL is 0.3 dB higher and RL is 5 dB lower, ER is 2dB lower (PM type) for each connector added. The pass optical power is 2 W only for connector added.
Package Dimension
*Due to ongoing design improvements, the package size is subject to change. Different fiber core diameters / NA, different beam diameter, different package sizes will be used, please contact DK Photonics for confirmation.
