A response from Adam at Thorlabs to fahd: We have three methods for stripping this type of fiber. The first is using a mechanical stripper, which would not work for your application. The next two might:
Method 2: Chemical
Dip in solvent for a few minutes. Jackets will absorb the solvent
and swell up. Grab fiber between thumb and index finger (with some
tissue in between) and rub swollen portion off.
Method 3: Hot Sulfuric Acid
Hot sulfuric acid (T=150-180°C). Dip a few minutes or until all
acrylate is dissolved. Rinse in clean water after excess acid is
drained off. Then, rinse in acetone, then isopropyl alcohol and
blow dry.
I will email directly with more information about method 2.

Hello, i have bought SMF-28-100. I have a problem of stripping this fiber. I want to strip from middle in 1 meter fiber but could not, it always break.
its very rough from inside. dont know what to do.
I appreciate if you can help me.
thanks
bye

Below Left: Using a source outputting at 1996 nm and a Ø30 mm mandrel, the bend losses (dB) of the SM2000 and SMF28 fibers were measured for each turn of the fiber around the mandrel. Based on the measurement, the loss/turn of the SM2000 fiber is ~0.08 dB. For the SMF28 fiber, the loss/turn is ~3 dB. The SM2000 fiber is much less sensitive to bending than SMF-28e fiber.
Below Right: Power as a function of distance is shown. The measurements were obtained by starting with 150 m of SM2000 fiber and measuring power output after a series of cut backs. For this measurement 1996 nm input light was used.
