Description
1x2 CWDM Device (3-port)
The CWDM multiplexes optical signals of different wavelengths into a single optical fiber for transmission, and decompose them into signals of different wavelengths at the receiving end. Because of the advantages of CWDM's wide band and low requirements for system equipment, it has occupied an important position in the access layer of the metropolitan area network. Vsunlight's 1x2 CWDM Device(3-Port), Operating Wavelength:1260-1620nm,Passband IL0.6dB, Reflection IL0.3dB, T-ISO 30dB. All devices fully comply with the Telcordia GR-1209-CORE/ GR-1211-CORE standard and meet the PCT 168 hour .

 | Lower insertion loss
Low insertion loss make CWDM devices have lower signal attenuation when used in wdm systems,which reduces the power requirement for signal transmitters. |
High Isolation The high isolation makes 3port CWDM device use in the WDM system to isolate the signals adequately when transmitting multiplesignals, and effectively prevent the signal from being distorteddue to the crosstalk between the signals. |  |
 | Mature Production Process Vsunlight CWDM device has a mature production process.Theoptical path is made by non-glue and semi-automatic conditionpackaging. It has stable and reliable performance. It supports thework in the harsh environment of -40 ~+85℃, and ensures thestable transmission of signals. |

Optical Circulator
An optical circulator is a unidirectional three-port device with irreversible transmission that allows light to travel in a specific direction. According to their physical principles, circulators can be divided into non-polarization-maintaining circulators and polarization-maintaining circulators.
