Product Description

• Fiber Optic Filter Wavelength Division Multiplexer (FWDM) is based on environmentally stable thin-film filter technology.

• This devices combine or separate light at different wavelength in a wide wavelength range.

• They offer very low insertion loss, low polarization dependence, high isolation and excellent environmental stability. High power handling capability can be achieved through unique pigtail processing and high quality AR coating.

• These components have been extensively used in EDFAs, Raman amplifiers, WDM networks and fiber optical instruments.

• Filter Wavelength Division Multiplexer (FWDM), FWDM T1550 R1310&1490 can achieve 1550/1310 &1490 two channel optical signal multiplexing and demultiplexing.

• Making single optical fiber transmission capacity multiplier, widely used in optical fiber network upgrading and CATV etc.

• The device features low insertion loss, epoxy free optical path, high extinction ratio, high reliability and high stability.

• Package way: Steel tube, ABS black modular box.

• Bare optical fiber, 0.9 mm, 2.0 mm, and 3.0 mm Input/Output Cable.
