Using our CE-1000 cabinet and plinth range, we can offer full or partial height 19″ rack frames with 90º or 180º opening. Our 19″ rack components allow a full range of options, which are suitable for heavy load fixing, fixed (>70 kg), removable and sliding shelves (>40 kg). What are 19 integrated racks? Integrated 19 in racks are complete rack systems that house electronics, power, cooling, and mechanical interfaces in a standardized 19-inch format — providing a pre-engineered platform for mounting and protecting equipment in control rooms, data centers, or rugged. That's why our industrial IT system integration service is based on one principle: no compromise on structure. Discover robust 19-inch cabinets, racks, and subrack systems from nVent SCHROFF, engineered to protect critical electronics in aerospace, defense, industrial, and telecom applications. These 19" frame enclosures are used to place computer servers, audio installations or networking equipment.

A Variable Optical Attenuator (VOA) is a controllable device used to reduce the optical power traveling through a fiber or free-space optical path. The optical fiber built into each device is single mode over the specified operating wavelength. We offer the industry's most extensive selection of fiber variable optical attenuators (VOAs), addressing all application scenarios with best-in-class performance and value. These operate by collecting and collimating light from an input fiber and then reflecting this light off of an ultra-stable and reliable, single-axis DiCon MEMS mirror.

As light in fibers often does not have a well defined polarization state, it is important that a fiber-optic attenuator exhibits only a minimum amount of polarization dependence. Generally, the obtained insertion loss has some dependence on the optical wavelength. For multimode devices, however, some loss difference is possible in conjunction with a mode dependence.

An optical attenuator, or fiber optic attenuator, is a device used to reduce the power level of an optical signal, either in free space or in an optical fiber. The basic types of optical attenuators are fixed, step-wise variable, and continuously variable. The power reduction is done by such means as absorption, reflection, diffusion, scattering, deflection, diffraction, and dispersion, etc.
