  1. Above specification are for device without connector, and may change without notice.
  2. Other package dimension and optical performance can meet customer design.
  3. 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.

Order information P/N: LBFC (PMLBFC)-①-②-③-④-⑤-⑥

When you inquire, please provide the correct P/N number according to our ordering information, and attach the appropriate description would be better. For high power applications, we recommend direct splicing without connectors
