LUNA PCD-104 – Polarisation Scrambler
- Minimal Insertion Loss and Back Reflection
- Low Residual Phase and Amplitude Modulation
- Remote Operation Wavelength Control
- Built-in RS-232, GPIB and Ethernet ports
The LUNA PCD-104 Scrambler uses patented all-fiber technology to randomize polariation states. Specifications include low insertion loss and low back reflection as well as minimal phase and amplitude modulation. The instrument can be used in automatic test systems under remote control through digital interface options.

Notes: 1 For SMF-28 compatible fiber. Other fibers may have higher loss, especially wtih connectors.2 Please note that the fiber used determines the operating wavelength range. The standard fiber covers wavelengths in the 1260 to 1620 nm range. The PCD-104 can also be configured to cover the 980 to 1310 nm range using a different fiber. This fiber can handle wavelengths up to 1650nm, but if it is coupled to SMF-28 fiber, the performance may not be quite as good as normal due to mode mismatch. Please contact General Photonics for details. 3 Center wavelength ±50 nm. 4 At 500Hz detection bandwidth. 5 Measured by a photodetector at the PCD-104 output using a spectrum analyzer. A polarizer is placed in front of the photodetector toconvert polarisation modulation to amplitude modulation.
