SFT 01xN Singlemode Splitters

SFT-SWB    Wavelength Independent
SFT-S35        Dual Windows Wideband
 

The OPTOKON SFT-SWB wavelength independent couplers/splitters are designed to transmit optical signals within the full CWDM wavelength spectrum. The SFT couplers/splitters are ultra reliable devices featuring low backreflection, low insertion loss, and high port isolation over wide ranges of temperature and wavelength. The SFT couplers/splitters are designed to divide and/or combine different optical signals in optical fiber systems. With its innovative Fused technology process, the SFT series couplers/splitters have proven to provide exceptional characteristics for all applications demanding critical performance. The splitting ratio can be customer specified to meet your needs. Available in a wide variety of packaging configurations, these SFT series are operable in all 1310 nm 1550 nm and 1625 nm wavelength ranges. Various types of pigtailing and connector terminations are available to meet your requirements.

The OPTOKON SFT-S35 dual windows wideband series are operable in both 1310 nm and 1550 nm wavelength range.
