Mini FWDM device 3 ports Filter WDM for 1310 1490 1550

FWDM--Filter Wavelength Division Multiplexing (FWDM) is based on mature thin film filter technology, with wide channel bandwidth, low insertion loss, and high channel isolation
It is widely used in single-mode optical fiber communication systems and DFA for its high degree of environmental stability and reliability.

Features

  1. Wide Operating Wavelength Range
  2. Low Insertion Loss
  3. Ultra Flat Wide Passband
  4. High Channel Isolation
  5. High Stability and reliability
  6. Epoxy-free on Optical Path
  7.  

Applications

  1. Testing Instruments
  2. FTTH Tri-Play System
