PWDM is similar FWDM,they are all run wavelengths 1310/1490/1550nm,specification also similar,but the different is PWDM pass end with one PD,FWDM pass end with one connector usually is SC/APC.PWDM PD generally fix on circuit board to use.
1)Low insertion loss
2)Broadband transmission
3)High isolation
4)High stability and reliability
1)Metro network
2)WDM system
3)Fiber optical amplifier
4)5G FrontHaul
