Tunable Filter

Description

Tunable bandpass filter for continuous wavelength tuning from 1420 to 1630 nm

The Multiple Application Platform (MAP) Tunable Grating Filter Cassette is a tunable bandpass filter that offers continuous wavelength tuning from 1420 to 1630 nm. It is used for applications requiring low insertion loss (IL), high rejection, narrow bandwidth and wavelength tuning resolution of 0.005 nm.

The standard model has a maximum input power of 300 mW and the high power option provides a maximum input power of 1000 mW.

Three options are available:

• the peak search option, used to find the absolute maximum transmission power within the filter's wavelength tuning range or a local maximum transmission power within a user-defined wavelength range
• 10% tap option for power monitoring
• 50% tap option for power monitoring.

MAP Tunable Grating Filter Cassette is ideal for applications where the user needs to suppress amplified spontaneous emissions (ASE) or isolate specific wavelengths. These applications include amplifier characterization, bit error rate (BER) testing and optical signal to noise ratio (OSNR) measurement.

The MAP Tunable Grating Filter Cassette is the next generation replacement of the Benchtop Tunable Grating Filter (TB9 series)

Applications

• Spontaneous emission suppression
• Amplifier characterization (Up to 1 W of input power)
• BER testing
• Tunable laser based testing

Key Features

• Narrow bandwidth
• Low polarization dependent loss (PDL) (< 0.3 dB)
• Wide wavelength range (1420 to 1630 nm)
• High power input (1 W)
