• Fiber is hand selected to ensure higher cutoff wavelength. For SM operation near the cutoff wavelength, launch conditions need to be taken into consideration.
• MFD is nominal, calculated value, estimated at the operating wavelength(s).
• Attenuation is specified for unterminated fiber.
• Attenuation is a worst-case value, quoted for the shortest design wavelength.
• Return Loss is defined for the unterminated connector. For example, if your source is connected to the FC/PC end, your return loss will be the FC/APC measurement of 60 dB.
• Insertion loss increases for fibers with small MFDs; typically those that operate at lower wavelengths. The typical alignment error in a mating sleeve is due to core-cladding concentricity and mechanical tolerance in the connector on the order of approximately 0.5 – 1.5 µm. Insertion loss serves as the overlap integral between the MFD on the input fiber and the output fiber. This alignment error causes only a few percent loss for fiber with a larger MFD, but as the mode field diameter decreases, the mechanical tolerances have a larger impact.
• For FC/PC and FC/APC connectors. Insertion Loss is not specified for SMA connectors because they use an air gap for fiber-to-fiber connections.
• All FC/PC and FC/APC connectors feature a 2.0 mm narrow key.
