CWDM (1×2) Packed with Rich Features

Toronto, Canada – GAO Tek Inc. ( has rolled out its coarse wavelength division multiplexer (CWDM) appropriate for use in WDM networks, telecommunications, cellular applications, fiber optic amplifiers and access networks. The multiplexer utilizes thin film coating technology and is characterized by low insertion loss, high channel isolation, wide passband, low sensitivity to temperature and an epoxy free optical path.
This coarse wavelength division multiplexer maximizes existing fiber optic infrastructure by transmitting multiple wavelength signals through the same fiber optic cable. It operates over a wavelength range of 1510 to 1610nm with 20nm channel spacing. The CWDM enables a dual fiber strand to support multiple network topologies and data rates to exponentially increase bandwidth capacity. It also enables immediate flexibility by increasing the capacity of existing fiber infrastructure, eliminating the need to lay new fiber at full capacity locations. This coarse wavelength division multiplexer is encapsulated within a non-flux metal bonding micro optic packaging and offers highly stable performance even in demanding environments.
