150GHz C-band Flat top 32-Channel Athermal AWG, DWDM MUX DEMUX LC/UPC 1U RACK     Introduction   The 150GHz 32ch DWDM MUX DEMUX operate in C-band. And it meet the following specification over the operating temperature.   Definition Note:    All specifications should be guaranteed at the worst-case polarization state and over the entire operating environmental condition and end of life. The Insertion Loss of a device is defined as the maximum loss at a defined wavelength, taking into account the worst-case polarization state over the full operating temperature range. The Insertion Loss Uniformity of a device is the difference between the insertion loss of the best-case and worst-case channels. The Polarization Dependent Loss of a device is the maximum insertion loss difference between all polarization states at the defined wavelength. The Reference Passband is defined as a band of wavelengths around each center wavelength. It is used in the definition of crosstalk. The Adjacent Isolation of channel is the maximum insertion loss difference from the mean transmission at the ITU grid wavelength to the highest power over the all polarization and the ITU band of two adjacent channels. The Non-adjacent Isolation of channel is the maximum insertion loss difference from the mean transmission at the ITU grid wavelength to the highest power over the all polarization and the ITU band of the non-adjacent channels. The Total Crosstalk of channel is the total cumulative insertion loss difference from the mean transmission at the ITU grid wavelength to the highest power over the all polarization and the ITU band of all other channels including adjacent and non-adjacent channels. The Wavelength Accuracy is defined as the maximum difference between the defined wavelength and the center of measured 3dB passband.   Product Penal                           150GHz DWDM MUX DEMUX 32CH 1U Rack Technical Parameter   Parameter Specification Units Notes Min Type Max Channel Spacing 150 GHz   Nos of Channel 32 Ch   Channel Frequencies ITU Grid THz   Available Channel Frequency Range 191.2   196.7 THz   Channel Passband -60   +60 GHz   -0.48   +0.48 nm   Center Wavelength Accuracy -0.05   +0.05 nm   -6.25   +6.25 GHz   Insertion Loss     5.5 dB @Center Wavelength     6.0 dB Full Bandwidth Passband Ripple     0.6 nm Full Bandwidth Bandwidth @1.5dB 135     GHz   Bandwidth @3.0dB 160     GHz   Bandwidth @20dB     310 GHz   Insertion Loss Uniformity at ITU     1.50 dB   Polarization Dependent Loss     0.5 dB   Adjacent Channel Isolation 13 15   dB   Non-Adjacent Channel Isolation 30 35   dB   Total Cross Talk 11 13   dB   Directivity 50     dB   Return Loss with connectors 40 45   dB   Chromatic Dispersion -20   +20 ps/nm   PMD     0.5 ps   Optical Power Handling of Common Port     24 dBm     Operating Conditions   Parameter   Min Max Units Temperature   -5 70 ℃ Humidity Non-condensing 0 90 % R.H.   Storage Conditions   Parameter   Min Max Units Temperature   -40 85 ℃ Humidity Non-condensing 0 90 % R.H.   Channel Plan 32Port AWG - On grid   The AWG operate in C-band.

As emerging technologies like 5G, the Internet of Things (IoT), and cloud computing develop at a fast pace, there is a steady rise in bandwidth demand. To keep up with this demand, Passive Optical Network (PON) technologies are advancing as well. Currently, the primary PON technologies in use include GPON, XGS-PON, and NG-PON2; meanwhile, OTDR (Optical Time Domain Reflectometer) serves as a tool for diagnosing network faults and carrying out maintenance work. By leveraging 4CH WDM (Four-Channel Wavelength Division Multiplexing) technology, these various technologies can coexist on a single fiber—this not only boosts the network’s bandwidth but also improves its flexibility.
