Mini Size Wide Band Coupler (NSWBC)
DK Photonics uses bandwidth expanding techniques (asymmetric techniques) to build the wide band coupler(WBC). The WBC has an operating bandwidth of ±40nm, low excess loss and PDL.
The mini size WBC 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.
