The 1550nm SM Filter Coupler using advanced micro-optic filter technology, offers very low excess loss, broad operating band and high stability and reliability. These components are extensively used with large-core double-clad fiber, multi-mode fiber, as these fibers cannot use the FBT process to make fused couplers.

- Above specifications are for device without connector. All parameters are tested at room temperature.
- For devices with connectors, IL will be 0.3dB higher, RL will be 5dB lower. Power transmits through the connector less than 2W.
- For >10W high power applications, we will use heat sink package, contact us for details.
- If there is pulse application, please be sure to inform us of pulse energy and peak power.
Package Dimension
- Due to ongoing design improvements, the package size is subject to change.
- High power device package must be mounted onto heat sink (active cooling is suggested) with thermal paste.

P/N: SMFC-①-②-③-④-⑤-⑥-⑦
When you inquire, please provide the correct P/N number according to our ordering information, and attach the appropriate description would be better. If need any connector, we do not recommend choosing a 250μm bare fiber pigtail.
