5G Compact CWDM Solution
VSunlight’s CWDM series multi-channel filters are used to increase/decrease several sets of CWDM optical wavelengths, of which the wavelength is 1271,1291......1611 nm in the CWDM ITU grid (20 nm spacing), the number of common channels is 4CH, 8CH,18CH. This series of filters are generally used for module packaging. All versions are designed for outdoor using with temperatures ranging from -40 ℃ to +85 ℃.
Athermal AWG
VSunlight’s AWG is a spring passive device based on planar waveguide technology that requires no additional power or other power supplies. It has the advantages of low loss, high integration, good uniformity and so on. A variety of channels, encapsulation modes and extended ports are available. Widely used in MAN,WDM Transmission, Optical Add/Drop Multiplexing and so on. P grade are designed for use in an outdoor environment within a temperature range of –40 ℃ to +85 ℃.
CEx Module
A WDM module or coexistence element is designed to enable the implementation of gigabit passive optical network (GPON) evolutions to XGS- PON and NG-PON2. Engineered for scenarios where services are already guaranteed using GPON but the deployment of different FTTH access technologies is desired, including Optical Time Domain Reflectometer (OTDR) signal too. In other words, CoEx elements enable the convergence of multiple services over a common access network, allowing flexibility while saving on costs.
CWDM Device
VSunlight’s CWDM series single-channel CWDM are three-port filters that are used to add/drop a CWDM wavelength to/from a set of CWDM optical wavelengths, where the wavelengths are 1271, 1291. . . . . .1611 nm on the CWDM ITU grid (20 nm spacing). The filters are available in different versions of packaging, like SUS tube or glass tube only. All versions are designed for using in an outdoor environment within a temperature range of –40 ℃ to +85 ℃.

DWDM Device
VSunlight’s DWDM series single-channel DWDM are three-port filters that are used to add/drop a DWDM wavelength to/from a set of DWDM optical wavelengths, where the wavelengths are CH20, CH21. . . . . . CH62 on the DWDM ITU grid (0.4 nm or 0.8 nm spacing). The filters are available in different versions of packaging, like SUS tube or glass tube only. All versions are designed for using in an outdoor environment within a temperature range of –40℃ to +85℃.
DWDM Solution
