FBT Splitter

Fused Biconical Taper is to tie together with two or more optical fibers, and then fused stretching in the biconical tapering machine , and monitoring the real-time change of splitting ratio, after splitting ratio meet requirements, fused stretching is overed, one side retain a single fiber (the rest is cuted) as input port, another side is regarded as multi-channel output port.In some applications that are not very sensitive to volume and light wavelength, FBT splitter is more affordable.Feature● Low Insertion loss● Wide Operating Wavelength● Compact Size● Excellent Environmental & Mechanical StabilityCoupling Ratio(%) | 50/50Directivity (dB) | >55Operating Temperature (°C) | -20 - +70Storage Temperature (°C) | -40 - +85Fiber Type | Corning Singlemode SMF-28, DS Fiber, or flexcoreFiber Pigtail Length (m) | 1Port Configuration | 1x2 or 2x2Package Dimension | Package 3.0x54mmSingle mode Standard Coupler | Single mode Standard CouplerGrade | PremiumCoupling Ratio (%) | 50/50Excess Loss (Typical )(dB) | 0.1Maximum Insertion loss (dB) | 3.4Polarization Sensitivity (dB) | 0.1Operating Wavelength (nm) | 850, 980, 1310, 1480, 1550, 1585, or custom wavelengthSingle mode Wideband Coupler | Single mode Wideband CouplerGrade | PremiumCoupling Ratio (%) | 50/50Excess Loss (Typical )(dB) | 0.1Maximum Insertion loss (dB) | 3.4Polarization Sensitivity (dB) | 0.1Operating Wavelength (nm) | 1310+40, 1550+40, 1585 +40, or custom wavelengthCoupling Ratio/Insertion Loss Conversion ChartCoupling Ratio | Insertion Loss40/60 | 4.4/2.530/70 | 5.6/1.820/80 | 7.4/1.110/90 | 10.8/0.65/95 | 14.6/0.42/98 | 19.0/0.21/99 | 21.0/0.2Single mode Dual Window Wideband Coupler | Single mode Dual Window Wideband CouplerGrade | PremiumCoupling Ratio (%) | 50/50Excess Loss (Typical )(dB) | 0.1Maximum Insertion loss (dB) | 3.6Uniformity (Max.)
