GAO Tek Launches CWDM for Fiber-Optic Amplifiers

GAO Tek, manufacturer of electronic measurement devices, has launched a coarse wavelength division multiplexer (CWDM) that is ideal for fiber-optic amplifiers, cellular applications, telecommunications and WDM networks.

The multiplexer features an optical path that is epoxy-free and is characterized by low temperature sensitivity, broad passband, high channel isolation and low insertion loss. The instrument uses a thin-film coating technology.

The CWDM enhances the present fiber-optic infrastructure by transporting several wavelength signals via the same optical fiber cable. It functions over a wavelength range from 1510 -  1610 nm with a channel spacing of 20 nm. The CWDM allows a dual fiber string to support numerous data rates and network topologies to enhance the bandwidth capacity.

The CWDM allows instant versatility by enhancing the capability of present fiber infrastructure. It removes the requirement to install new fiber at complete capacity locations. The CWDM is housed inside a metal bonding micro optic package and provides stable performance in adverse environments.
