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.

Features:

• 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

Applications:

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