Function
● 40 channel DWDM optical signal multiplexed into one fiber
● 40 channel optical signal de-multiplexer to single-wavelength signals
Highlight
● 40 Channel Multiplexer and Demultiplexer (MUX & DEMUX)
● Plug and play: requires no configuration
● Green product: completely passive, needs no power and no cooling
● Low insertion loss, insertion loss ≤6dB, typ 4.5dB
● Uniform insertion loss variation over the 40-channels - less than 1dB (typical 0.6dB)per MUX or DEMUX
● High channel isolation
Adjacent isolation ≥25dB
Non-adjacent isolation ≥35dB
● High reliability, MTBF of 100 years
