Ultra Narrow-band Optical Transmission Filter
Application | Features | Packaging | ||
This device is your perfect choice to filter signals with a very low FWHM, down to 500 MHz in the optical domain. In opposite to standard FBG components, the module does not reflect any signals. Hence it can be used with laser applications without the need of an isolator.
|
The Ultra narrow transmission filter allows to select signals with a narrow bandwidth, while reliably blocking any other spectral components. |

Operating Temperature | 10° .. 45° | |
Termination | FC/PC, FC/APC, ST, SC/PC, SC/APC, DIN, SMA | |
Packaging | Table top box | |
Max. input power | 500 mW | |
(*) The IL might be higher at an FWHM that is smaller than 0.008nm (1 GHz) |
