Condition: Used
Please note the key barrel has been removed and so it powers on with the button.
This Santec OTF-930 polarisation-independent optical tunable filter covers a dual-band wavelength range of 1527–1610 nm across two 2-stage filter elements (08S2 type), with FC/SPC connectors and a -3 dB bandwidth of 0.65 nm per channel. A Finisar Calibration label (M17496) is affixed to the front panel. Please note the key barrel has been removed; the unit powers on via the front-panel button.

Included in the sale:
• Santec OTF-930 optical tunable filter unit
• FC/SPC optical connectors (OPT.IN and OPT.OUT on front panel)

The Santec OTF-930 is a bench-top optical tunable filter employing Santec's proprietary Linear Sliding technology using dielectric thin-film filters. Two filter elements, each covering a 40 nm wavelength range, are mounted on a stepper motor-driven slider to provide seamless tuning across the full 80 nm range. The instrument does not require thermal control, ensuring excellent wavelength stability. A wide selection of filter profiles is available with 1, 2, or 3-stage cascade configurations (S1, S2, S3). The OTF-930 is suitable for laboratory and production environments and includes a built-in optical power monitor and peak search function.

Key Applications:
- ASE noise suppression in EDFA-amplified DWDM systems
- Individual ITU grid channel selection
- Tunable incoherent light source when combined with a broadband source
- Optical signal noise filtering for transmitter and system testing
