Since the early days of fiber optic research Bentham has been supplying systems for measuring fibre spectral loss. This experience will soon become apparent when you start to use the SMR4000:

. easy-to-use bare fiber clamps

. no need for X and Y axis positioning of fiber

. highly magnified image of fibre end for easy inspection of fiber cleave and contamination

. excellent reproducibility

. simultaneous measurement of both branches of devices

. Windows software guides operator through measurement sequence for 1x2, 2x2, 1x3 to 1x8

Wavelength range: 900 to 1700nm (option 350 to 1700nm)

Measurement reproducibility: 0.02 dB

Attenuation measurement: to 40 dB with 5nm bandwidth

Minimum bandwidth (max resolution): 1nm

Wavelength accuracy: better than +/-0.3 nm

Wavelength repeatability: +/-0.08 nm

Measurement speed: Typically 2£f’s per second

Typical measurement time: For wideband coupler, 980/1550 WDM, etc is 2.5 minutes. This includes time for

Fiber handling: Spring-loaded fiber clamps

Fiber alignment: No XY positioning required; Z position datum

Fiber viewing: Monitor provides x250 magnified image of fiber end for easy Z positioning,

Windows software guides through sequence of operations. Outputs insertion loss, excess loss, coupling ratio, isolation and ASCII files.
