Amplifies the optical signal to a certain power value or by a gain factor.
pypho_osnr.__init__(glova)
Instantiation and parameter setting.
| Parameter | Type | Description |
|---|---|---|
glova |
instance | Global parameters as defined in pypho_setup. |
| Output | Type | Description |
|---|---|---|
| User defined variable | pypho_meanpow.pypho_meanpow |
pypho_osnr.__call__(E, OSNR (optional), f (optional))
| Parameter | Type | Description |
|---|---|---|
E |
list | List which defines the optical data and noise signal. Read here about data signal and noise representation. |
OSNR |
float | OSNR in dB where noise power is normalized to 12.5 GHz. |
f |
float | Frequency at which the OSNR is set or read out. Default value is gp.f. |
| Output | Type | Description |
|---|---|---|
| User defined variable | User defined varable | If OSNR is set in the call, then a list is returned in which the optical data and noise signal are defined (more). The noise vector is scaled, so that the OSNR at the frequency f is set.If no OSNR is defined in the call, then the return value is a float. The value is the OSNR at the frequency f.
