OSNR is measured at 0.1nm resolution bandwidth.
Note •
• Receiver performance is always specified for a BER < 10e-12
Note When shorter distances of single-mode transceivers are used, it might be necessary to insert an optical
attenuator in the link. At least 1 dB of attenuation is required to prevent damaging the optical receiver,
and at least 9 dB of attenuation are required to avoid receiver overloading conditions.
