2×2 Polarization-Maintaining Fiber Coupler FSC2219-980P-APC
A polarization-maintaining fiber coupler combines polarization-maintaining fiber with a micro-optical system and is suitable for fiber-optic products incorporating polarization-maintaining systems or requirements. JCOPTIX's 2×2 polarization-maintaining fiber couplers have 2 input ports and 2 output ports and offer three coupling ratios: 1:99, 10:90 and 50:50. At each coupling ratio, the 2×2 polarization-maintaining fiber couplers have 11 center wavelengths (670nm, 780nm, 850nm, 915nm, 980nm, 1030nm, 1064nm, 1310nm, 1480nm, 1550nm and 2000nm), covering 670-2000nm. Powers without connectors are 2W, 1W and 100mW. When connectors are fitted, a maximum optical power of 2W or 1W becomes 300mW, while a maximum optical power of 100mW becomes 50mW.
