Questions & Answers
  • Q:

    What's the difference between this product and #35887? By Nutting on 17/05/2019


    Thanks for your question, the differences between them are the insertion loss and monolithic technology. This product adopts AAWG Flat-top monolithic technology, the insertion loss is less than or equal to 6.0dB; #35887 uses AAWG Gaussian monolithic technology, the insertion loss is less than or equal to 5.0dB. But they have the same function in DWDM networks. By FS on 17/05/2019
