BoxOptronics 1310nm 1550nm L-Band Polarization independent Optical Isolator is a fiber-coupled in-line polarization-independent isolator that Fiber isolators protect light sources from back reflections and signals that can cause intensity noise and optical damage. Optical isolators, also known as Faraday isolators, are magneto-optic devices that preferentially transmit light in the forward direction while absorbing or displacing light propagating in the reverse direction, It is widely use in protect against reflections, which can corrupt some measurements or damage lasers and amplifiers. This 1310nm 1550nm L-Band Polarization independent Optical Isolator can be single or double/dual stage depending on the degree of required optical isolation of the propagating light.

Low Noise 1550nm Nanosecond Pulse Fiber Laser Module For DTS Sensor System can be used in fiber laser, fiber sensor system and other applications.

1550nm 20mW SM Fiber Coupled Laser Diode is mainly used as the optical signal for high-capacity long-distance optical communication, as well as a wide range of new applications such as fiber sensing, 3D sensing, gas sensing, and disease diagnosis such as respiratory and vascular monitoring. In the field of gas sensing, it is used as the light source for gas sensors that detect methane gas leaks around factory pipes.

This 1610nm 5mW TO-CAN DFB Laser Diode is a product operable over a broad temperature range with a low temperature-wavelength coefficient. It is well suited for applications such as communications research, interferometry, and optical reflectometry for distance measurement in fiber or free space. Each device undergoes testing and burn-in. This laser comes packaged in a 5.6 mm TO Can. It contains an integrated aspheric focusing lens in the cap, allowing the focus spot and numerical aperture (NA) to be matched to SMF-28e+ fiber.

The 980nm 1030nm 1064nm high power fiber optical isolators is a fiber-coupled component that allows all polarized light signal (not just the light polarized in a specific direction) to propagate along a fiber in one direction but not in the opposite direction. Functionally, it is quite like an optic-electrical diode. The 980nm 1030nm 1064nm high power fiber optical isolators are necessary in fiber optic systems in many roles the most common of which is the prevention of back-reflected light coming back down a fiber from re-entering and disrupting the operations of a laser. Boxoptronics provide 1W,2W,3W,...,10W or other high power Polarization maintaining fiber isolators.

850nm 10mW DIL Package Superluminescent Diode sld diode SLED is a light source for ophthalmic and medical OCT application, fiber transmission systems, fiber optic gyros, fiber optic sensors,optical coherence tomography, optical measurements. The diode is packaged in 14-pin standard butterfly package with monitor photodiode and thermo-electric cooler (TEC). Module is pigtailed with single mode polarization maintaining fiber and connectorized by FC/APC connector.
