Programmable Optical Tunable Filter OTF-930

80nmTunable Filter

The OTF-930 bench-top type tunable filter has wide variety of filter profile options with combining filter type and number of cascaded filters (S1,S2,S3) to suit most fiber optic applications. It features full 80 nm improved tuning mechanics and improved low insertion loss. Low PDL and low PMD are also characteristic of Santec “linear sliding” filters.

OTF-930 equips GPIB and RS-232C control interface which enables remote control and data acquisition.

Features

• 80nm tuning range, 0.01nm resolution
• Low insertion loss
• Low PDL (<0.1 dB) & low PMD (<0.1 ps)
• Power monitoring and peak search functions
• Full GPIB support with LabView driver

Applications

• ASE noise suppression for amplified signals
• Wavelength channel selection from WDM multiplexed signal
• Incoherent tunable light source combining with broadband light source
• Optical transmitter / receiver evaluation
