    Connector Type:
    Coupling Ratio:
    Pigtail Type:
    Port Number:

Dual-window optical coupler combines and splits incoming light over 1310nm and 1550nm wavelength simultaneously, and offers wide bandwidth (+/-40nm) for both windows.

This type of couplers are used in systems where those two wavelength windows are required, such as WDM, FTTx systems.


  • Dual window broad operating band (+/-40nm bandwidth at 1310 and 1550nm)
  • Low excess loss (no more than 0.1dB for grade P products)
  • Low PDL (no more than 0.1dB for grade P products)
  • High stability and reliability


  • Optical communication systems
  • LAN
  • CATV
  • Optical fiber sensors



Ordering Information:

a: Port Number of the coupler; a=1x2 or a=2x2.
b: Quality Grade of the coupler; b=A for standard grade coupler; b=P for premium grade coupler.
e: Coupling Ratio of the coupler; e=50/50 for 50% coupling ratio; e=10/90 for 10% coupling ratio; e=5/95 for 5% coupling ratio, etc.
c: Fiber Pigtail Type; c=0 for 250 micron bare fiber; c=1 for 0.9mm loose tube pigtail, etc.
d: Connector Type, d=FA for FC/APC, d=SU for SC/UPC, d=N for no connectors, etc.

Example: DWC1315-1x2-A-40/60-1-SA
