The document describes a 1550nm 10mW SLD broadband light source module that utilizes a single mode fiber and can be customized for adjustable power via RS232 communication. It features a low coherence spectrum and high output power, applicable for optical OCT and fiber sensing. Testing with infrared photosensitive film confirmed the module's functionality and produced a visible light spot.

1. 1550nm SLD Broadband Light Source
Single-mode Fiber Laser Module
This is a 1550nm 10mW SLD light source of module type. It is equipped with a single mode fiber.
It can be customized power adjustable version. When the power adjustment is selected, the
power adjustment is controlled through the RS232 serial communication. The standard version is
a fixed power mode, the light source is controlled by the button. We tested it with an infrared
photosensitive film, and we could see a light spot. Let's check it now.

SLD broadband light source adopts super radiant semiconductor diode light-emitting chip, which
outputs broadband spectrum with low coherence degree and high output optical power spectral
density. The operating wavelength can be selected from O, S, C, L and other bands, suitable for
optical OCT, optical fiber sensing applications.
