The PM FWDM series wavelength division multiplexer provides wavelength division multiplexing while maintaining signal polarization. These components are based on environmentally stable thin film filtering technology and have the characteristics of high extinction ratio, low insertion loss, and high return loss. They are very suitable for high-speed WDM network systems.
High extinction ratio: The minimum extinction ratio of PM FWDM series is usually above 20dB, which means they can effectively suppress unwanted polarization states, thereby improving signal quality and reliability
.
Low insertion loss: Insertion loss is an indicator of the loss of optical signals when passing through a device. The typical insertion loss of the PM FWDM series is between 0.3 and 0.6dB, with a maximum insertion loss not exceeding 0.8dB, which helps minimize the power loss of the signal during transmission
.
High return loss: The minimum return loss of the PM FWDM series is usually above 50dB, which means they can minimize the optical signal reflected back to the light source, thereby reducing interference and noise in the network
.
High isolation: The minimum isolation of the PM FWDM series is between 12 and 30dB, which helps ensure independence between signals of different wavelengths and prevent interference between signals
.
Environmental stability: The thermal stability of the PM FWDM series is usually below 0.005dB/ºC, which means that the performance of the equipment changes very little at different environmental temperatures, ensuring the stability and reliability of the network
.
Maximum optical power processing capability: The PM FWDM series can handle up to 300mW of continuous wave optical power, making them suitable for high-power applications
.
Maximum tensile load: The PM FWDM series has a maximum tensile load of 5N, which means they have good mechanical stability during installation and use
.
Working temperature range: The PM FWDM series has a working temperature range of -5 to+70 ºC, while the storage temperature range is -40 to+85 ºC, which allows them to be used in a wide range of environmental conditions
