Molex Fiber Optic’s family of Polarization Maintaining (PM) cable assemblies is specifically designed to provide high Extinction Ratios (ER) with accurate alignment to the
key and low insertion losses. Polarization Maintaining fiber is a type of singlemode fiber that preserves the plane of polarization of light launched into it as the beam
propagates through its length. Utilizing proprietary assembly techniques, connectors, and customized testing processes, Molex is able to offer PM fiber assemblies that
are precisely aligned to either the mechanical plane (with respect to the stress rods), or to the optical plane (active alignment with respect to the launched optical signal).
All assemblies are tested for Insertion Loss, Return Loss and Extinction Ratio to ensure the highest quality assemblies are supplied.
Molex has developed stable processes for termination of PM fiber into industry standard connector types including SC, ST, FC, LC, and MU as well as blind mate
backplane connectors including the BSC and BLC connectors. The unique feature of PMF terminations is that the fibers must be accurately aligned with respect to the
connector key. The alignment ensures that when two PM fibers are mated in an adapter, or when a PM assembly is connected to a polarized source, the optical
polarization planes are in close alignment to minimize optical losses.
Alignment is typically performed to the slow axis, however other orientations are achievable. Molex utilizes the Panda PM fiber construction, available in 1300nm and
1550nm wavelengths as a standard, other fiber types and wavelengths can be supplied. Assemblies are also available with either a standard PC type polish or an 8°
angled polish for lower Return Loss requirements.
