Project Description
Mini Size Dual Window Coupler (MSDWC)
Dual window coupler (DWC) is built by asymmetric coupling technique. The operating bandwidth of this coupler is expanding to ±40nm. The DWC coupler has the same coupling ratio on both 1310nm and 1550nm communication windows.
The mini size DWC is designed for the compact optical modules and communication systems.

Order information P/N: FBTC-①-②-③-④-⑤-⑥-⑦-⑧-⑨-⑩
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. For mini size coupler, typical applications are bare fibers without connector.
