What are the specific applications of the 1625nm wavelength in optical fiber communication
Multimode fibers, optical amplifiers and regenerators all communicate at wavelengths outside normal traffic windows. 1625 is ideal due to the transmission properties of optical fiber. This wavelength is used in a variety of applications requiring high power stable IR radiation. In optical communication systems it is often necessary to test fiber while the optical link is carrying live. The OTDR transmits a light pulse based on the wavelength while the fiber link is operational. The filtered 1625 nm or 1650 nm wavelengths could be vital for in-service maintenance and evaluation, eliminating the interference of live traffic. In fiber optic systems, specific optical wavelength bands are used based on performance, attenuation, and compatibility with amplification technologies.

Automatic Adjustment of Fiber Optic Collimator
The autocollimator is a very sensitive angle measuring device and is thus used for the precise angular adjustment of optical or machine components. Due to the collimated beam (infinity adjustment) the measurement results are independent from the distance to the object under. Thorlabs offers a variety of fiber collimation and coupling solutions. FiberPorts can be used to provide a stable platform for coupling light into and out of FC/PC, FC/APC, or SMA terminated fiber with five or six directional adjustments. This article delves into the principles, applications, and benefits of using auto-collimators for optical assemblies. Via the collimator functionality, the structure engraved on the reticle is imaged to infinity. The device under test is placed in the optical path and reflects the light back into the. When do you need a separate micro focus optics? For spots < 10 times the mode field MFD of the fiber, a good quality spot can no longer be achieved by simply refocusing the collimation optics.
