    1x2 Triplexer 1590nm WDM Coupler

    Model TWFC-1x2-159
    Price:   US$99.00
    Available Options:
    Connector Type:
    Pigtail Type:

This WDM coupler combines or separates L band wavelength (1570~1610nm, center at 1590nm) with wide range of wavelength from 1260nm to 1560nm (that includes the triplex wavelength 1310nm, 1490nm and 1550nm). It helps to separate the 1590nm channel or L band from other windows in FTTH systems, CWDM systems or DWDM systems.

This WDM coupler is based on thin-film filter technology, that ensures low insertion loss, wide operating wavelength range, low PDL and high environment stability.


  • Low insertion loss
  • Low PDL
  • High wavelength isolation
  • High stability and reliability


  • Optical fiber triplexer FTTH networks
  • WDM systems


Order Information:
