Power combiners are available in 6:1, 7:1, 18:1, or 19:1 ratios. Combiners are specified with various input- and output-
fiber NAs. Output
fiber coating diameters are available in various combinations of 220, 250, or 300 µm. Other options include: single-mode/multimode/polarization maintaining; and ytterbium doping for 1 µm or erbium/ytterbium doping for 1.5 µm applications. Coupling efficiency to single-mode, multimode, or PM
fibers is specified, as well as
optical return loss, maximum power...
