Athermal AWG

  • 40/48 Channel 100 GHz DWDM combined Multiplexer and Demultiplexer (MUX & DEMUX)
  • Plug’n play: requires no configuration
  • Green product: completely passive, needs no power and no cooling
  • Uniform insertion loss variation over the 40-channels – less than 1dB (typical 0.6dB)per MUX or DEMUX
  • Compatible with 100GHz ITU Grid DWDM active transponders and transceivers from Fiberroad and other third parties
  • High reliability

Athermal AWG is a high performance DWDM mux/demux product based on silica-on-silicon planar technology (AWG or arrayed waveguide gratings). It has a unique athermal packaging design that achieves temperature compensation passively with no requirement on electrical control. It is a completely passive module that has high stability and reliability. Athermal AWG combines standard 100GHZ DWDM ITU grid channels 21 through 60, and Applies to FR-8000 chassis, occupying 2 service slots. The AAWG is ideal for increasing the fiber capacity between two sites without the need for installing or leasing additional fibers. The complete passive solution requires no power cabling and no configuration; it is a true plug and play solution. Athermal AWG enables separation of the active equipment from wavelength multiplexing components. It is used in conjunction with active optical devices applied in C or L-bands wavelength range with MAX expanding up to 48 channels.It offers a combination of low optical insertion loss and high channel isolation along with long term reliability and low cost per channel.

Q & A

Q: Will this DWDM Mux Demux provide customized sevices? A: Yes, we can customize your Mux perfectly tailored to your specific needs. Any wavelength, any connector, any housing and any special ports can be achieved.   Q: Passive CWDM vs DWDM – Which to choose? A: Generally, CWDM offers a convenient and cost-efficient solution for short distance, low capacity, sub-10G. While DWDM supports long haul applications with speed protocols of up to 100G/200G per channel.
