Fiber Cost Optic Coupler Fwdm 1310 1490 1550 Nm with Steel Tube with ce certificate top quality low price

Product Description

Filter WDM module extensively used in optical amplifiers, WDM networks. The device combines or separates light at different wavelengths (1310nm/1490nm/1550nm) in a wide wavelength range. It can expand the capacity of a single fiber to achieve bidirectional communication, so that widely used in optical network upgrade and expansion, or introduce new comprehensive business etc.It works on 1310nm/1490nm, so CATV signal here is delivered over same fiber using 1550nm, and FWDM is a place where all this get together.
