1550nm DFB Fiber Coupled Butterfly Laser Diode Manufacturers

In communications, Four Wave Mixing (FWM) is a coupling effect between light waves caused by the third-order polarization real part of the fiber medium. It is caused by the interaction of two or three light waves of different wavelengths at other wavelengths. The production of so-called mixing products, or new light waves in the sidebands, is a parametric nonlinear process. The reason for the four-wave mixing is that the light at a certain wavelength of the incident light will change the refractive index of the optical fiber, and the phase of the light wave will be changed at different frequencies, resulting in a new wavelength.

In data centers, optical modules exist everywhere, but few people mention them. In fact, optical modules are already the most widely used products in data centers. Today's data centers are basically optical fiber interconnection, and the situation of cable interconnection has become less and less. Therefore, without optical modules, data centers cannot operate at all. The optical module converts electrical signals into optical signals at the sending end through photoelectric conversion, and then transmits through optical fibers, and then converts the optical signals into electrical signals at the receiving end. That is to say, any optical module has two parts: transmitting and receiving. The function is to do photoelectric conversion and electro-optical conversion, so that the optical modules are inseparable from the equipment at both ends of the network. There are thousands of devices in a medium-sized data center.

Box Optronics is a mature DFB laser source supplier in China. Guided by customer needs, it has launched a multi-channel DFB laser source that integrates multiple different wavelengths. Multiple wavelengths can be activated and used simultaneously, or only one wavelength can be operated separately. This laser source can be used for WDM devices, AWG devices, PLC devices, EDFA, and other fiber optic measurements and applications. The compact product structure is only for more efficient optical experimental research and development applications.

The 980nm 14pin butterfly pump laser produced by Box Optronics uses a TEC cooler and a 980nm Pump laser chip with high performance.

Box Optronics provides 974nm 976nm pump laser modules for optical communication. A pump laser is a laser used to provide necessary energy to the gain medium of another laser or laser system. The light can excite other laser media to produce stimulated emission. It is often used in fiber amplifiers and solid lasers as an energy source.
