    Tunable Filter with Fixed Bandwidth

    Model: XFA

    Manufacturer: Yenista - France

    Yenista's tunable filter technology provides the best optical features for telecommunication applications. The XFA is electronically controlled and wavelength tuning ranges from 1450 nm to 1650 nm. The bandwidth is factory-installed and can be selected when you purchase between 50 pm and 800 pm with respect to the center wavelength.

Key Features

Fixed Bandwidth Flat-top Filter

The bandwidth of the XFA filters can be selected at purchase between 50 pm and 800 pm. The filter has a flat-top profile with minimal ripple, less than 0.2 dB.

Ultra-sharp Filter Edges

The XFA uses Yenista's patented quadruple pass technology. This creates extremely sharp filter edges with slopes of 500 dB/nm. Single or groups of narrowly spaced DWDM channels or coherent super-channels can be selected with ease.

High Isolation

In addition to the sharp filter edges, Yenista's quadruple pass technology achieves higher isolation than conventional double-pass filters. Isolation is typically 60 dB.

High Accuracy & Repeatability

High resolution translation stages are used for wavelength control. This ensures the XFA can be set accurately and repeatedly over time.

200 nm Wavelength Range

The XFA has a very wide wavelength range and covers the key telecom wavelengths from 1450 nm to 1650 nm.

Easy-to-Use Software

The XFA is operated through its 7-inch touch screen to drive all operations. It enables fast setup with a complete set of functions such as sequence execution, ITU Grid selection, custom grid generation.

Applications

DWDM Channel Selection

Low dispersion, steep edges and high isolation mean that DWDM channels, or even coherent superchannels with spacing down to 10 GHz, can be separated with ease. BER tests have never been so good!

Variable OSNR Source

A variable OSNR source typically consists of an ASE source combined with a variable attenuator. Adding the XFA with a flat-top bandwidth enables consistent noise loading for all DWDM wavelengths.

R&D of Modulation

Formats The XFA is perfect for the filtering and analysis of subbands of complex modulations formats.

Pulse Shaping

Wide bandwidth flexibility enables the filter to be used for pulse shaping of femtosecond lasers.

Advanced Features & Performance

Easy access to optical connectors for cleaning. Easing maintenance and enabling the lowest losses to be maintained.
