#OPTICAL ISOLATOR 1550NM CODE#
Wider operating bandwidth, other center wavelengths or higher power handling options are available upon request. Specifications Type 40 dB Standard Fiber-optic Isolator Fiber Type Singlemode Fiber Connector Bare Fiber Operating Wavelength 1550 nm Maximum Insertion Loss 0.5 dB Typical Insertion Loss 0.4 dB Return Loss 65/60 dB Maximum Optical Power 300 mW Operating Temperature -20 to 60C Option Code 10 Polarization Mode Dispersion <0. It has low polarization dependent loss, 40nm operating bandwidth and high peak isolation of 50dB. Since the polarizer is vertically aligned, the light will be extinguished.įigure 2 shows a Faraday rotator with an input polarizer, and an output analyzer. This isolator is specially designed to work at 1310nm or 1550nm wavelength. This means the light is polarized horizontally (the direction of rotation is not sensitive to the direction of propagation). The Faraday rotator will again rotate the polarization by 45°. Light traveling in the backward direction becomes polarized at 45° by the analyzer.
The analyzer then enables the light to be transmitted through the isolator. The Faraday rotator will rotate the polarization by 45°. Light traveling in the forward direction becomes polarized vertically by the input polarizer. The polarization dependent isolator, or Faraday isolator, is made of three parts, an input polarizer (polarized vertically), a Faraday rotator, and an output polarizer, called an analyzer (polarized at 45°). 250um-coating without connector.Features Polarization independent Low polarization mode dispersion Low insertion. Insertion loss < 0.5dB is shown on each component case, see 1st two photos below. It is similar to YD-5S, but it offers better insertion loss. In-Iine optical isolator over C-band : YD-360-D-155S. It is made of three parts, an input polarizer, a Faraday rotator and an analyzer. 1.55um is marked on component, as shown at last photo below. Figure 2: Faraday isolator allows the transmission of light in only one direction. Optical Isolator 165010nm 5.5×35, 900um,1m FC/APC IL1.2dB Optical Isolator 165010nm 5.5×35, 900um,1m FC/APC IL1.
