Applications
l ASE Noise Suppression
When optical signals are amplified using EDFAs, unwanted levels of amplified spontaneous emission (ASE) can decrease the signal-to-noise ratio. The OTF-930 with 08-S1, 08-S2 or 12-S2 filters can remove the ASE noise with minimal loss.
l Wavelength Channel Selection
The 03S2 filter configuration is particularly suitable for selecting a single DWDM wavelength from a 100GHz grid. Other filters can be used to select other ITU grid spaced signals.
l Incoherent Light Source
When used in combination with a broadband light source the OTF-930 can be configured as a tunable light source. Although the output power is relatively low (-30 to 20dBm) the incoherent light is especially useful for applications which are affected by coherent resonance effects or non-linear interference.
