Project Description

All Band Coupler (ABC)

All Band coupler (ABC) is built by Special technique. The operating bandwidth of the coupler is expanded to 1260-1620nm, and with low excess loss and low PDL.

Features Applications
  • Low excess loss
  • Low PDL
  • All Band operating Wavelength
  • High stability and reliability
  • Optical communication systems
  • CATV
  • FTTH

  1. Above specification are for device without connector, and may change without notice. All parameters are tested at room temperature.
  2. Other specifications can be made on customer request.
  3. For devices with connectors, IL will be 0.3dB higher, RL will be 5dB lower. The pass optical power is 2 W only for connector added.
  4. If there is pulse application, please be sure to inform us of pulse energy and peak power.
  5. Insertion Loss around 1383nm (water peak) is counted in the specifications above.

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.
