Box optronics independently developed dual emitter laser source module adopts DFB semiconductor laser chip, single-mode fiber output, professional design of driving circuit and TEC control to ensure the safe and stable operation of laser.

The 1450/1550/1660nm 1x3 Raman Filter WDM for DTS Systems Module is manufactured by using thin-film filter technology, it used to separate and combine different signal wavelengths at 1450nm, 1550nm, and 1660nm (or 1650nm). This 1x3 Raman Filter WDM with low insertion loss and high isolation Characteristic. It's widely used in Raman DTS systems or other fiber test or measurement systems.

BoxOptronics 1060nm 1480nm polarization independent Optical Isolator is a fiber-coupled in-line polarization-independent isolator that transmits all polarized light (not just the light polarized in a specific direction) efficiently in one direction but block transmission in the opposite direction, It is widely use in protect against reflections, which can corrupt some measurements or damage lasers and amplifiers. This 1060nm 1480nm polarization independent Optical Isolator can be single or double/dual stage depending on the degree of required optical isolation of the propagating light.

The 1310nm 1mW SLED or SLD Superluminescent Light Emitting Diodes is highly qualified SLEDs for a diverse range of Fiber Optic Gyroscopes(FOG) applications. These SLEDs can operate over demanding temperature ranges, increased shock/vibrations levels, and have verified long lifetimes due to their use in defense and space environments.

Manual Fiber Polarization Controllers is made by the principle of birefringence generated by optical fiber under the action of external force. The three rings are equivalent to λ/4, λ/2 and λ/4 wave plates respectively. The light wave passes through the λ/4 wave plate and is converted into linearly polarized light, and then the polarization direction is adjusted by the λ/2 wave plate. The polarization state of the linearly polarized light is changed to an arbitrary polarization state via a λ/4 wave plate. The delay effect caused by the birefringence effect is mainly determined by the cladding radius of the fiber, the radius of the fiber surround and the wavelength of the light wave.

The DWDM DFB Butterfly analog Laser Diode For CATV Application is a Dense Wavelength-Division Multiplexing (DWDM) laser for analog applications. It features a distributed feedback chip that has been designed specifically for Radio Frequency (RF) applications. The DWDM DFB Butterfly analog Laser Diode has a wide temperature range for reliable performance in harsh node environments and narrow transmitter designs. It also features low adiabatic chirp to maximize signal quality in short and long lengths of fiber. The laser’s excellent inherent linearity minimizes degradation of the broadcast signals caused by quadrature amplitude modulated (QAM) channels. The versatile DWDM DFB Butterfly analog Laser Diode reduces cable network architecture fiber needs and lessens equipment requirements in the hub.
