Frequently Asked Questions

Seven standard sizes: 50, 110, 200, 300, 400, 600 and 800 µm core diameter.

Low-OH fiber extends usable transmission further into the near-infrared (to 2200 nm) at the expense of some UV/visible transmission — the opposite trade-off to High-OH fiber (250–1200 nm).

The metal coating conducts heat away from the fiber under high optical power, unlike a polymer coating, while also providing hermetic sealing and a much higher maximum operating temperature.
