GEZHI offers a full range of DWDM Mux/Demux(Dense Wavelength devision multiplexer) and Optical Add Drop Multiplexer (OADM) units to suit all kinds applications and network solutions, such as: Gigabit & 10G Ethernet, SDH/SONET, ATM, ESCON, Fibre Channel, FTTx and CATV.
Here in the class of our DWDM Mux/Demux, we offer Filter type DWDM/OADM, Thermal AWG with power supply unit, Athermal AWG modules. 50G/100G/200G AWG as a most competitive series of GEZHI's product range, has been accepted and tested by the whole industry.
GEZHI standard filter type DWDM Mux Demux products provide up to 48 wavelengths Multiplexing on a single fiber while for AWG series, we offer up to 96 channles with 50G AWG module at C-Band. Standard DWDM Mux/Demux package type include: ABS box package, Special metal box, LGX pakcage and 19” 1U rackmount.
GEZHI AWG DWDM is by silica-on-silicon planar technology. The AWG chips GEZHI Photonics used for DWDM Mux/Demux are targeted for Long-Haul, Metro and access applications, where outstanding optical performance and low cost are paramount.
Athermal Arrayed Waveguide Grating (AAWG) DWDM Modules features of athermal packaging design require no electrical power, software or temperature control.
Thermal Arrayed Waveguide Grating (TAWG) DWDM Modules are designed for use within the C-band release of DWDM system. To decrease the power dissipation of the devices in different environmental conditions, the AWG package is special designed with selection of reliable thermal plastic with low thermal conduction, and the AWG operating temperature is controlled by using foil resist heater or Peltier TEC with thermistor temperature sensor.
The channel spacing for DWDM is 1.6/0.8/0.4 nm (200GHz/100 GHz/50 GHz grid). This small channel spacing allows to transmit simultaneously much more information
