Motorized Polarization Scrambler Wavelength Range Of 1200 ~ 1610nm
In the design of high-speed optical communication network system,
the polarization of light wave is an important factor that cannot
be ignored. With the increase of speed, optical fiber communication
system is more sensitive to polarization related damage. Such
damages include: Polarization Mode dispersion (PMD) in optical
fibers, Polarization Dependent Loss (PDL) in passive optical
devices, Polarization dependent modulation (PDM) in
photomodulators, Polarization dependent gain (PDG) in optical
amplifiers, Polarization dependent wavelength (PDW) in WDM filters,
Polarization Dependent Response (PDR) in receivers, Polarization
dependent sensitivity (PDS) in sensors and coherent communication
systems.
The U8340 Motorized Polarization Scrambler is a program motorized control
polarization scrambler. Its polarization controlled capability
enhances measurement speed, accuracy, and overall prodUtivity. The
continuous length of fiber enables high power and ultra-low
insertion loss. This design offers a wide range of Auto Scan rates
and high incremental angular resolution. Four-fiber knob loop
design has proven to provide excellent control with ultra-low power
variations (PDL). This reliable design allows for a wide range of
applications from component testing to PMD related activities.
