Application:
When optical signals are amplified with EDFAs, unwanted amplified spontaneous emission levels (ASE) can reduce the signal-to-noise ratio. The OTF-930 has 08-S1, 08-S2 or 12-S2 filters to remove ASE noise and reduce damage.
-
Wavelength channel selection
The 03-S2 filter is ideal for selecting single DWDM wavelengths from the 100 GHz grid. Other filters can select other ITU grid spaced signals.
When used with a broadband light source, the OTF-930 can be used as a tunable light source. Although the output power is relatively low (- 30 to - 20 dBm), the incoherent light is especially useful for applications affected by coherent resonances or non-linear interference.
