Alliance Fiber Optic Products (AFOP) recently released a line of polarization-maintaining fiber-optic assemblies for telecommunications applications. The line includes fiber-optic jumpers and pigtails, collimators and fiber-array units that the company says satisfy the requirements in 100-GHz coherent and related communication-system subassemblies. All these products are designated "PM," or polarization-maintaining.
AFOP said, "With high extinction ratio and low insertion loss, AFOP polarization maintaining products improve manufacturing yields and overall product performance." They are available with FC, LC and SC terminations, with UPC or APC polish.
