1650nm Reflector LC/APC

The  fiber  brag  grating  reflector( FBG  Reflector)  is  a  low-cost  specific  band  reflector mounted on the optical network unit (ONU) side. It can reflect light pulses ( 1650 +/- 5 nm) from the OTDR on the fiber line terminal (OLT) side nearly 100%, while the working bands of the passive optical network (PON) are transmitted normally. The OTDR can determine whether the  fiber  line  is  normal  by  detecting  the  signal  reflected  by  the  fiber  grating reflector. When the reflected signal is lower than the normal value, the line loss is too large; when the reflection value is 0, the optical fiber line is broken 。Therefore, we can maintain the fiber line in time by the real-time monitoring of the fiber line.

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.
