Project Description

Mini Size Standard Coupler (MSSSC)

Mini size couplers are designed to meet the requirement of the optical modules and fiber systems where need the small coupler package size. DK Photonics develops the mini size SSC with high stability and reliability.

Features Applications
  • Mini size
  • Low excess loss
  • Low PDL
  • High stability and reliability
  • Mini size EDFA
  • Mini size transmitter/receiver module
  • Optical communication systems
  • Testing instruments

  1. Above specification are for device without connector, and may change without notice.
  2. Other specifications can be made on customer request.
  3. IL is 0.3 dB higher and RL is 5 dB lower for each connector added.

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.
