Project Description

1xN (2xN) Single Mode Coupler Module

1xN (2xN) coupler splitter modules are cascaded with the single mode couplers. These modules are widely used for FTTH, LAN, and CATV optical networks.

Features Applications
  • Low excess loss
  • Uniform power splitting
  • Rugged package
  • Excellent environmental & mechanical stability
  • Long-haul telecommunications
  • Digital, hybrid and AM-Video systems
  • CATV systems
  • High speed local area networks
  • Fiber sensors

  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.
  4. If there is pulse application, please be sure to inform us of pulse energy and peak power.

Order information  P/N: FBTC-①-②-③-④-⑤-⑥-⑦-⑧-⑨

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.
