All about the product:
Description
The optical fibers offered by Shelyak Instruments are optimized for use in astronomy, particularly with the eShel and Whoppshel systems.
Specifications
Length: 10 or 20 meters, stainless steel protection.
Connectors : FC-FC
Multimode Fiber
Numerical aperture : NA = 0,22
Core diameter: 200µm for calibration fibers
A 5mm-diameter stainless steel sheath provides optimum protection… even at night (no risk of breakage if you step on the optical fiber).
Note: losses mainly occur in the junctions, at connector level. The transmission of the fiber itself, up to some dozens of meters, is close to 100%. As a result, the attenuation (<0.5dB) is valid regardless of the optical fiber length (5, 10 or 20m).
