What is the required signal-to-noise ratio for optical modules
OSNR is the measure of the ratio of signal power to noise power in an optical channel. In this section we focus on the optical SNR and consider electrical SNR in the next section. The dominant noise in long-haul systems is amplified spontaneous emission (ASE) introduced by optical. -

Communication Networks for Fiber Optic Communication Applications
Because the effect of dispersion increases with the length of the fiber, a fiber transmission system is often characterized by its bandwidth–distance product, usually expressed in units of ·km. This value is a product of bandwidth and distance because there is a trade-off between the bandwidth of the signal and the distance over which it can be carried. For example, a common multi-mode fiber with a bandwidth–distance product of 500 MHz·km could carry a 500 MHz signal for 1 km or a 1000 MHz sig. -
